ah sorry looks like maybe an editing error in my rush - i put a clip in twice and missed the lead in clip! Have i mentioned i am terrible at YT and social media...
3 years going with an emersion waxing my mtb chain with no perceivable wear. No greasy marks on my leg. No expensive degreaser and still on the same silica wax. Let the haters hate!!
it is such a strange thing to hate on!! I totally get that if its not for someone, then fine - all groovy and normal. but to hate on that option for others to enjoy the benefits - thats just whackadoodle land! Strange hill to fight from.... but it is a strange ol world these days..... Many things make me feel very sane and normal which is nice hahahahaha
@@justinfournier1285 Love the Abbey chain tool, but it looks like it's a bit of a waste of money. With no chain wear, who needs it?! Then again, the tool can be used to confirm all the bonuses of immersion waxing. And with all the money you'll save on chains, cassettes and chain rings, might as well splurge on the Abbey Tools beauty!
The other day I did my first immersion waxing of my MTB chain (aux bain Marie with plain candlewax (parafin)) and it performed awesome. 358 km in a week of (dry) gravel without a hitch. I did add squirt lube at the end of the week (after 300 km) but I doubt it was necessary. Thank you for showing me how easy it is.
One of the biggest reasons I went with Shimano 12speed mechanical grx was cost of ownership. I’ll keep testing to the .5 wear point. So far I’m hitting over 10,000km with hot wax with little to no wear. And the chain rings look great.
hahahaha yes indeed! oh my lordy it is going to be something alright, but..... its ok, for all the abuse soon to be coming my way, i might be able to open the eyes of the not yet scientologied followers. There are still those with functioning thinking brain out there in his followers vs just H coolaid cult followers where the ability to actually assess any information on merit has left the station awhile ago... your situation was pretty nuts. But hold my beer - wait to you see this all unfold!
Did you see Cyclowax were testing an on-bike immersion wax machine at the TDF? Can't post link because YT... article was on bikeradar "Spotted | Lidl-Trek using prototype automatic chain waxing machine at the Tour de France". My guess is it might work for this specific scenario - where the chain will get re-waxed frequently. But probably won't be as good as traditional potting. At 30 minutes per chain, it definitely is not as efficient - I mean couldn't the mechanic remove, immerse, dry and re-install an entire team's worth of chains in 1 hour? Curious to know what you think of this, maybe you could tell us in this week's vid?
Yes indeedy - that is something for sure. Whether it proves practical / of benefit or not - i am yet to be convinced, but i will always give kudo's to small new player like CW having the courage to invest and try to drive innovation in a particular space. There would be quite a lot of hurdles for that product- i actually think the hurdles are much bigger in the pro peleton that a fancy home workshop set up / user. A pro team would need a lot of them, and thats a lot to carry round, and they are no doubt pretty expensive, and especially until absolutely dialed and reliable - could there be a risk one didnt do what it was supposed to have done and left a rider on a big stage without a lot of lubricant. Pulling ones chain out of the wax pot after swishing - one knows what they are getting. Vs say popping circa 10 chains off a bike (10 mins), and putting 10 chains into a large pot to re wax all at once, then re install after set - would that be more labour time than getting 10 x bikes into wax machine? what maintenance does the wax machine itself need etc etc - but - who knows - like all v1 products maybe this one is a bit clunky, but the learnings from this one mean v2 is a lot better, and v3 rips. There is only one way to go from hmm im not sure to oh baby you rock my world and that is to have the courage and drive to get v1 out there, so i really like their innovation, investment and having a grand ol crack - im not personally convinced yet, but i am open to be, and i wish them every success. I have spoken to CW a number of times on a number of things over the last few years and they really are very passionate about the customer and customer experience, so as a company i like them a lot and i think overall they made a lot of great moves already with training wax and race wax tablets, the pot and stand that was copied to a large degree by silca (a big player copying you is a good compliment!) and more.
Yep my plan at the moment is to dominate master 10 category. Hence i am currently carb loading and putting on some kg's for my "strength building" phase - which is planned for the next some decades to get proper strong ready for the "complete and utter domination phase" in my 90's and 100's. I've found most people only have 5 year or 10 year plans. Suckers.
The Reginald Scot vid " Hambini Wants To Fight Me! " says it all ! DR might be distracted now with the ultimate narcissistic act ? Maybe he's trying to be the Ron J of the cycling world ?
DRs whole sub base (and the world) bursts into laughter when he states he coaches world tour riders, any riders for that matter.. Cant imagine Pog getting on the phone to talk sugar water, rim brakes and only fans porn while getting ready for the tour. 🤣🤣🤣
A few Halo observations that don't need an answer, please read with a very sarcastic tone. Let's hope you get some answers soon until then. Here is a comment to up your video engagement :) Since Finish Line would never put abrasive additives in their products I am doing a mental run of the single application longevity test. Let's take the Halo drip lube in block 1. I have read comments on your videos and you have said that the wear is pretty even through the block. That would indicate that drip lube would hit the 20% wear at 100km. You then divide that number by 3 to get the real world adjusted wear rate jump point estimate. This leaves the clean dry conditions adjusted rate at ~33km for 20% and 167km for 100% wear. Finish Line should take that kind of data and start marketing it. Can you imagine the TRUE statement "A single application of our lubricant will last the life of your drivetrain." I might have to take some of this testing into my own hands. 167km seems like a reasonable distance for a normal person to check in the real world. I will get on it when my current chain wears out. Currently my hot melt waxed chain has ~4000km on it, and my shiny new Abbey chain checker says 0% wear. Thanks for the recommendations, Adam. I believe you did not take the testing far enough. I am quite sure that block 4 is where this "lubricant" would shine. I believe block 4 performance would have shown better performance than block 1. I am sure that the cleansing effect of water and dirt might remove the additives causing the issue. The block 4 improvement would be a positive test result for Finish Line. You must really have a grudge with Finish Line to not continue the testing. That would mean that the Halo products may have been the first lubricant to improve with contamination. Can you imagine the marketing Finish Line could put up around that claim.
Ha that is all very good!! If we dont get to the bottom of things, and re test when i get my hands on more commercially obtained halo if things are still similar i may check with you re royalties on that marketing line! On re test i will consider going well past the normal 0.5% stop point (i did with the drip wax, that went to 1% just in block 1 anyway omg) - but will depend a bit on how many tests banked up and also at a point it does get risky, and if we have already assessed that a product is bad there is just not too much point using valuable test time to keep confirming what we already know -but.... maybe if it is a truly historic wear occasion again like testing round 1....
Thank you for the work you do. It's amazing that the industry still makes so much garbage product and the bike shops continue to stock and sell it. Edit: I just subscribed
Good on you for your (fairly lofty) fitness goals! I wore out my resolve over nearly 40 years of road racing, with only mediocre shading to barely competent results (2 years in club/combine A-Grade/regular open racing was enough for my sanity & overall health) to show for it. I enjoy touring and gravel riding much more now, with only the next hill to conquer, and the next view to enjoy. I still like riding my road bike, but won't compete on the littlest hill, nor the most insignificant town-sign sprint. I've just lost the desire to 'beat' people. It's a phrase with aggressive, public-school rugby-playing roots.
I do barely any road racing these days although that was where i started - but i cant sprint worth a damn (i might be one of the first people whose sprint and FTP are nearly indistinguishable) and so dropping wheel suckers who can sprint, who dont work or when they do their turns its worse than if they just kept wheel sucking (ie - the crystal shoes syndrome) - and in general the road race scene - at least it was here - is generally pretty tense. its like most people and officials have done a course on how to be / act / seem more tense. The mtb / gravel / cx scene is just SO MUCH more relaxed and really friendly. I dont do it for the competitive aspect at all - its still fun if i jag a decent result, its still fun if i am miles off. There are just lots of cool friendly peeps out there been now racing with for years, often the courses are great, and its just a fun morning / day out. And with gravel theres groovy events that many dont race at all, they just use it for a grand ride day with friends or solo supporting a groovy event - so even for the least competitive, some of those are worth a look just for fun! But of course if one is enjoying how they are riding, stay the course- one persons pleasure can be anothers nightmare. Ie i have friends who love crits hahahahaha
everything is replaced in almost all instances - so new rings, cassette, pulleys (clean mech cage) and of course new chain. The instances where this is not done are if just testing similar base for mfg where we are doing much shorter tests (ie just block 1 vs full test or just one part of single application longevity test)
@@Lacking_something yes its also part of why the testing isnt cheap for paid private tests (although labour time is the biggest cost still by far), but it does add up for little ZFC for the tests done for open knowledge / league table.
@@zerofrictioncycling992 Yes, makes sense you would have to and I have also wondered about this (Inc bottom bracket, and trainer calibration too I bet) So many parts...no wonder you have your own shop. You need accurate comparisons and I bet some of the companies that haven't performed well would be looking for reasons to discredit results.
@@colinl2908 Bottom brackets thankfully last AGES. And i mean 100,000 / 150,000km + ages - things are just much less stress for motor driven vs pedal driven - so BB's are easy. Freehub bearings are the main maintenance as they take pedalling load (chain load in this case) and are small bearings -but i remove the spacer and run 5 of them vs 2 so get much longer intervals otherwise they need replacing every 2 to 3 tests vs circa 10 tests. And yes some do - but very quickly find they simply have no way to do so - the chain is simply being run on a bicycle drivetrain - and so to date no mfg i know has raised anything against the zfc test.
Btw, update on my fully refined paraffin wax: going to re-wax tonight after around 200 km. I think it could go another 100 km, but I have a feeling it would benefit doing it sooner rather than later. The new chain I started with is a cheap one (brand named Fluir from China). I went with 4 or 5 turps baths and 3 meth baths to be safe, but not sure it got everything out. Thinking of getting another chain and adding stearic acid to the wax and seeing if I can do a diy version of Silca's grease converter blocks.
It would be nice if commenters could add one bit of crucial information: road or mountain? Pretty big difference between the two. Knowing how bad conditions are where I ride, I'd expect a road chain to last 5X to 10X the miles of a mountain bike chain. And a track chain? 20X+! But that's a totally unsubstantiated guess. Either way, please specify!!!
@@dudeonbike800 Sure - the answer is neither! I guess road/track is the answer you're looking for; I only ride on the trainer because riding on the road in South Africa is suicidal. Trainer and bike are kept on a balcony and a bike cover is placed over them when not in use to reduce exposure to dust. The trainer is an Elite Suito. On the trainer I'm currently doing 'moderate' rides for an hour, trying to maintain 125 watts. Sometimes I'll throw in some 1 minute intervals at 200 watts. I'm also not sure I needed to re-wax so soon. I wasn't hearing any squeaking or grinding. It just 'felt' like shifting wasn't as smooth as it should be - but still totally rideable. I kind of enjoy the re-waxing process and my hands stay clean through out. So really don't mind doing it once or twice a month. The initial waxing is much less enjoyable, hence the curiosity to try stearic acid to reduce the amount of solvent stages for prepping a new chain.. I'm also running a relatively cheap drive train (Shimano Claris) and as mentioned a cheap chain (Fluir). Since it's under $10, I've ordered a second chain to experiment with. Jury is still out on how long it lasts (regardless of lube). Hope that was specific enough.
Just saw a German drivetrain brand called Enduo with some pretty wild claims that their chainrings and sprockets double chain life. Most interestingly they miss out every other tooth on the chainring! If it works then great.. but I can't help be feel a bit sceptical about the claims. I would love to hear you discuss this product and potentially test if its really a wonder product. They are actually offering samples.
yes that one is fascinating. I have had a chat with them, and it is possible they may look to book some testing to prove the increased longevity of chains / parts of that system. I dont want to shoot down any of their theories without a) better understanding and b) testing - however on first blush i do have, lets say, some doubts. I did run through some of the questions / doubts on the call, but i admit i was not able to get to an understanding of how their theory and system workings would improve longevity - but it is of course possible i simply lack the ability to understand their concepts. As i have a simple brain, some things i just keep bringing back to basic principles. The pedalling load must be taken by the chain. The load is going to be transferred through the link plates and pins, and these parts are going to move against each other as they articulate under load causing wear like all moving parts under load. If you half the number of links, you would essentially double the load on the ones remaining. They are aiming to counteract that load by locking it in the from the opposite direction as well from the pedalling force - which is a novel idea - but i struggle to grasp that we have directional load pedalling the bike forwards that is effectively locked static between the teeth / links on the ring and cassette. I think i get their theory / approach, but when i run that through watching the vids - it is just not how i see it playing out. If it did work, there would such a massive longevity jump as they have effectively neutralized the load on the moving link parts that it would have already been extremely easy demonstrate, and it would certainly be easily demonstrated in testing here - i would simply run one chain with control lube on normal chain ring and cog, and repeat with new chain same model same lube on Enduo, and see a very very big difference in chain lifespan. This is something they could have already easily replicated the resources to motorise a smart trainer are pretty small, and a drop compared to what has already been invested. Considering how such a night and day test result would help their marketing, i dont know why that hasn't yet been done. Quite a number of lubricant mfg's now have test set up same / similar to zfc for their own in house testing - it really is a low capex bar for mfg to verify performance - i must say the lack of this at this time is confusing for me. If i was me and i was looking to compete in the segment they are trying to compete it (which is largely vs belt drive) - as their chain system is single speed with hub / gearbox for cargo / commuting - I would simply go big. Increase the chainring size and corresponding cog size to the largest practical so that rider load / wear load is spread over as many links and teeth possible which will reduce load per link and tooth and also across a greater number of teeth and links for a large jump in wear life, and you also get an efficiency bump vs smaller. To me that is a vastly easier solution and one doesnt need proprietary rings, cogs and chains. Such a system with sram hardchrome treated chain - that is going to go far, cheaply and easily. i had plans to cover this briefly in a low friction news update - maybe this week now you have reminded me - but hope the above helps give you some extra thoughts on the system on top of your own
@@zerofrictioncycling992 Thanks for the detailed reply. Your thoughts are pretty much along the line or what I was thinking too. A related thought that just crossed my mind whilst reading your reply is that chain wear loads would be most reduced if it were possible to avoid any articulation of a chain within the section under load. In reality this would probably be very mechanically complex to do, but running larger cogs would reduce the amount of articulation needed as it wraps around the cog and therefore reduce the wear. I imagine that 10 tooth cassette cogs must wear the chain significantly more than even 11 or 12 tooth ones as there is an increasing large articulation within the chain under load as the diameter reduces. It's an interesting topic.
@@andyarchitect Yes its been well tested and covered by the likes of jason smith in the past and its why we see for TT's such massive chain rings being used as they are watts more efficient. Basically we have 3 aspects all adding up. Larger chainring = less chain tension for a given power. Ie the tension load in the chain for a 170mm crank on a 32t chainring is much higher than on a 60t chain ring. With a 60t chain ring the torque / leverage loss at the crank you gain at the back wheel with a correspondingly much larger cog for the same gear inches which has greater torque leverage to turn the wheel. And of course power = torque x speed = a 60t at 90 cadence has a much greater chain speed - so lower torque / tension in chain x greater chain speed = 250w power is still 250w power - but with a large chain ring and cog, that power is transferred with much lower tension load in the chain. And then the chain is articulating less at the chain ring, and for a given gear inches, articulating less over the larger rear cog. So we have less articulation, occurring at lower tension loads at both ends of the drivetrain which is a) more efficient and b) less wear. And then for this case we also have that wear being shared over more teeth on both ends, and likely more links of a chain as longer chain. So for race bikes larger rings is done for efficiency, but for the commuter / cargo space - it should be done for parts longevity. There might want to be some design tweaks perhaps on some bikes to enable much larger than current typical chain rings and cogs - but surely that has to be an overall simpler and easier path vs a proprietary new rings / cogs / chain with longevity extension physics that are going to be to most .... i have to take your word for it that it works like that. With big ring / cog - the basic mechanics / physics of torque / tension, lesser articulation, and more parts sharing the lower load - that is easy for most to understand in about 60 seconds. The reality is simply a cargo bike with a gear hub moving from a 40t ring and a say 17t cog to a 60t ring and (without using a calculator) i am guessing approx 25 to 28t cog is going to see a significant jump in wear life of all 3 components. If i was me and i was enduo i would be making enduo cranks matched to enduo 60t chainrings made from tool steel, and enduo tool steel cogs, and using sram hardchrome treated chains. They would have amazing long life cargo drivetrains, and i think a much easier sell as this basic physics is a) basic and b) absolutely simple reality of larger vs smaller for potential customers understand and enjoy. I think their path is problematic on many fronts re attaining commercial success. If they dont gain sufficient market traction - sooner or later seed capital investment funds will have to run out. So now if i was them and all they have invested, i would do both - stay the course with the theory, but make the big. At least one of things going on will absolutely give the customers a great longevity boost, and if both do, yeehaa
@@zerofrictioncycling992 Good points there. I hadn't thought about the fact that a larger rear cog will reduce the tension on the chain due to the extra leverage. You made some really sound points there for increasing durability of a drivetrain. Seems like Enduo may be reinventing the wheel without addressing all the basics first. Maybe you should change for consultancy work on this topic 😄
@@andyarchitect Ha! yeah i do the odd bit of advice indeed to some mfg re lubricants, but for companies like Enduo - if you are stepping into the space of innovating bicycle drivetrains - the above is pretty entry level info really, i feel certain they would have to be across all that as its been covered for a good while and to an engineer that would all be very obvious. However my guess is that it is simply to basic and boring a path to base a new exciting start up business on and get investment capital. A revolutionary new system like Enduo stands them apart as an exciting new innovation to drum up investment etc -where as just "umm - shouldnt we just go bigger?" it is unlikely to get any of those who like to invest in exciting new start ups heart racing. Alas even though sometimes the solution is obvious, its too boring. If you want to be an entrepreneur and launch an exciting and innovating new business in a space, you need something that looks exciting and innovating. Sometimes a products performance matches that, and sometimes..... its just all fluff and a dud vs much simpler and more obvious paths / solutions. Which one enduo really is will be exciting to find out one day if we can... But yeah - if i was me, i would just go bigger. Or if enduo's works as marketed, i would do that as well as go bigger :)
Hi Adam... Or Hambini fans. Before I watch this video. I have to tell you, Hambini is not living in China carbon composite industry. He called himself an engineer, but he don't know too much about composite materials.
Great information as usual, Adam. Congrats again on the 300th race. It really is astounding. And 2nd place at that! Well done. I also appreciate a little of your background. I find those things interesting. I followed Hambini for a little while several years ago but had to unsubscribe just because of what I consider to be a toxic personality. I know a lot of people like that and everyone is different. As for me, I just couldn't take it any more. I'll just see this as an opportunity for you to get even more good information to his viewers. Very much the same for DR. I watched several of his videos early on, mostly looking for vegan cyclists, but stopped fairly quickly. I can only speak for me, but I don't think you need to talk about him unless you need to defend yourself. Giving him any more oxygen than that just serves him. It's not worthy of your time. I sure don't need to know about it. That said, if you feel like it's important to bring up, then definitely do that. All of that said, gross. Have a great weekend my friend.
Thanks Cat! And ha yes correct i mostly try to avoid DR as despite the temptation to counter so much of his made up attacks on me / zfc - it does just give him what he looks for. But that news was just too omg to leave out, especially following on the from imminent H update as i believe those two are pretty buddy buddy (birds of a feather flock together as they say.... - i imagine both are graduates of Andrew Tates Hustle academy). Strange ol world out there...
ha yeah maybe, it is honestly not the best path to follow if we dont want to eat out some expensive and magnificent cassettes and chain rings, so it will be good to get the official thought paths from sram!
Added to the probability that SRAM wears the most, when you consider that campagnolo wears in, where shimano wears out, and campagnolo is the least popular- I use all 3.
@@richardhayward4537 Hmm tell me more about campy wearing in..... with regards to chain and drivetrain component wear - campy is not setting itself apart in any way as the parts are subject to the same challenges as all others. Their chains have very normal wear life, and same with cassettes and chain rings. From a chain / cassette and chain ring perspective, they most certainly don't wear in as others wear out. In fact there are some overall issues re campy in general such as.... > Their stance for a very long time against master links and removing chain for proper maintenance, in general leading to increased wear rates vs chains where the mfg is perfectly fine with you removing chain for waxing / proper flush clean maintenance. > Products that really benefit from such - as in ekar - the master links are $29.90!!!! And one really wants to keep the chain low friction and wear due to the cost of ekar cassette... > the super slick cabling to keep 12 / 13 spd mechanical systems shifting well again costs north of $100 aud, and like all cabling if used for normal volumes should be done circa annually. i could go on and on (such as the waste of including a 123 page instruction book in EVERY chain - have they not yet heard of the internet - what is cost and waste of that over say the last decade?) why do their eps batteries cost many hundreds when they are essentially exactly the same battery as axs which cost circa $100 - and yep - it never ends, and its all this stuff where they do not understand that it is simply driving them to probably be smaller drivetrain mfg that TRP in the future from what was once sheer market dominance. You dont go from market dominance to concerns of death whilst competitors grow ever stronger from great decision making and products. They have trended to where they are due to poor decision making, and a difficult prices to justify for comparative performance. I really want campy to live, and oh man i really wanted to put ekar on my gravel / cx bike - but i just couldnt, it just didnt / doesnt stack up to the competition - again, and things like $30 master links and $100+ cabling just means that i have to shake my head and sigh sadly, again, and go with a competitor...
@@zerofrictioncycling992 tour of timanfaya I used to work in a bike shop for a few years and learnt that campagnolo lasts so much longer, it was common for people to say campagnolo wears in shimano wears out, from middle aged cyclists and from the shop itself from colleagues. One thing you didn’t mention is the structural molecular build of campagnolo materials. I have 10 speed that I’ve had since 2010, I use 11 speed shimano ultegra and reluctantly recently bought a BMC 01 road machine with sram force (I bought because of the frame) at a great price. Using KMC chains is probably just as good as campy, but the other parts should outlast by at least twice. It’s a shame that campy has gone full EPS with no other options, but I will still persevere with 10 Speed and I’ve been getting some real bargains on eBay with chainsets I’ve recently bought, £70 for record chainset, and £100 for 11 speed SR(cross compatibility with 10 speed), hardly used condition. I can’t, for the life of me, imagine that campagnolo would downgrade the molecular construction, unless shimano and SRAM would up their materials, I suppose you could compare equivalent in 10 and 11 speed for lastability, and when you mention SRAM chain wear checker is only measured past worn point you can see their intentions. I cannot comment on 12 speed eps as I don’t have one, but may upgrade in time. I think campagnolo will have to change again because they have narrowed their own market which was already a niche one.

Interested to see what Hambini says as it's hard to debate facts. I watched a few of his videos a couple of years ago, but his shock jock style/banging his hairdresser rubbish put me off.
Just watch Hambini's headset replacement video to see how much of a hack he really is. Also Hambuni wouldn't know a thing about testing protocols. Josh at Silca in one of the marginal gains episodes (cant remember which one) proved Hambini could have never done all that aero wheel testing he claimed to have done. Might be worth having a chat to Josh to get the specifics for any response video 😜
thats a good idea thanks! Yeah he has a pretty massive amount of aero testing, which aside from the time and huge cost (who is covering that?) does seem rather difficult to do from ones lubricant factory.
sorry feedbackloopz if you feel that way - but yeah it is all quite extraordinary re a) the claims and tech apparently being used and b) the test results - i mean we have a latest gen lubricant and IM wax that appears to be actively abrasive as the wear rates are worse than no lubricant, something i never thought would see really. So it is all rather something in the little focus of lubricants, and i want to give FL the best opportunity to help us all understand. As i get further info (ie call with FL hopefully next week, the analysis results from the science lab, re test when i can get more product) - it will continue to be followed up and updates covered for a little bit yet i think - but if not of further interest it will be time stamped so you can skip it :)
@@zerofrictioncycling992 oh no, I will definitely not skip that part when they come up with some new excuse or unrealistic claim ;) I mean, it's your time and your channel after all, you decide how to use it
Is it any accident that SRAM are erring on the side of sloppy with their 0.8% replacement recommendation for chains, in the same little while that they have released the Red AXS XPLR groupset, the cassette of which retails for USD $649 (AUD ~ $1000!!!)? Which, if you don't wax and swap the chain (USD $70, AUD $130-150) regularly, and replace it/them at 0.5%, could have a lifespan as short as 5000-8000 kms? Who am I to question the wisdom of hegemonic US corporations, and their fleecing of impressionable idiot MAMIL/MAMIBs, with my mechanical 10 speed SLX/old Dura-Ace/Ultegra/Stronglight cheap-as-chips mullet gravel/CX/ghetto-trash drivetrain?
yes this is the very big concern, and honestly a chains performance itself starts to really deteriorate after 0.5% (refer silca velo vid on chain stretch done recently), as well as just guaranteeing will need new DT components. Yes their hardchrome chains are very wear durable, and yes their chain rings and cassettes (most models) are also hardy and wear durable - but 0.8% will simply ensure they are eaten out too much to take another new chain. And - as durable as their hardchrome chains are - that is still no match for how poor many commonly sold lubricants are by some big name brands - the ones most often stocked by LBS. So it can be big, big ouch basically annually for many - which is not cool. This call is apparently going to happen (not sure if this week....) but trust me i will be going hard on the above to get their take / reasoning!!
"All information contained on this website are fans’ personal views and/or findings that were collected over time and are not scientifically validated. " HAMBINI might be a liar, or not, but sharing links, to personal pictures, and shit.... its stupid sad and coward. Sad very sad

People should be aware as a start re SOME of the concerns of H, which will help me when it comes to responding to a malicious bullying attack. I would first ask why that website exists in the first place, and then ask who is the bigger victim - H, or the followers of information presented as fact and believed as such. If you disagree, i understand - not all will be agreeing with me on this, but... i reserve the right to defend against such an incredible internet bully of rather questionable honesty with all ammunition available to me.
You and Hambini do have a few things in common. The best thing is that you both want the best for the consumer. Calling companies out for failing on this.
Thanks mark! And yes it would be brilliant if things could have been different - ie you see how shane miller and DC rainmaker both help make the cycling information space better. I was really surprised, and very disappointed - when years back some basic clarifications on the steel vs ceramic bearing test and information were so quickly met with some rude words and to basically go F myself. I am sure outlook still has the email chains i can publish if i feel the need in my response. And simply since that i was on the shit list. Which i admit, i didnt help when for his initial years i found a number of his videos quite shocking re a) what i felt were very misogynistic, and b) just simply extremely bullying and very personal attacks on people. These video's are now deleted - he deleted i think about 2 years worth i think to keep his channel, as many of them really were just..... well there is highlighting concerns, or difference of opinion, or calling out - and then there is just flat out massively abusive bullying for shock value - and that is very much not me, and so when someone would link me with hambini - i would comment to the effect of please do not do that due to the above. This will have no doubt moved me much further up the shit list. But im not sure if you remember the one he did on xavier disley at aerocoach (who mind you has since proven very correct vs H re his aero work and products). H was SLAYING him abusive, calling him Mr Vagina Head, and probably out there riding a "Fat bottomed Womens bike", as well of course as the never ending use of the C word. One could say clever marketing to build channel through sheer shock value and drama - as well as of course generating as many lawsuits as possible again for shock and drama for channel growth - lets just say we are very different characters. And i think that approach attracts a lot of a certain type of follower, and they are not necessarily using their thinking brain, but will jump on ANYTHING he says - whether or not on that particular occasion it is merited. If he is annoyed by a product or company - his personal opinion is presented as fact, and very attacking, and people / companies are then on the receiving end of abuse they do not deserve. Going to be fascinating what he attacks me on, i am obviously going to be seen as biased here - but aside from being an overly verbose terrible presenter / talker on YT - i just dont know what about me / zfc there is to attack unless he is going to go durianrider style and just maliciously make shite up. We shall see! :)
@zerofrictioncycling992 Shane and DC should be almost compulsive reading. DC really does go into alot of detail writing his reviews up. Since your review on Muc off I binned their products and haven't looked back. Waxing is so much better. Keep on doing what you're doing 👏
"The boss has been on leave" give me a break. If your business is at risk, you reply (at the very least) asap. Will be so interesting to see what they say. Any update on the lab tests?
ah its ok - i get if on annual leave you go work incommunicado. FL wont be at risk due to little ol zfc having concerns - they sell around 20,000 units a month of FL dry just on amazon alone - they are doin alright thanks to legacy brand name (and remember from that they have massive penetration into LBS). And not yet - i have a feeling it will take awhile - it should have arrived there this week / early next week - so will start chasing up results in another week or two. I will hope to get the next call with FL this coming week though if possible and see how i go understanding these tungsten spheres and also what questions / concerns they have re zfc test.
I am incredibly disappointed in you for linking in your description that Hambini doxxing site created by AbsoluteBlack employees. How would you feel if the same if Finishline etc was equally upset with you for a negative review and decided to hire private detectives to follow you around taking pictures of you going to work in some petty attempt to discredit you and then referenced by other content creators on youtube who disagree with you. I'm sure you would be throwing a tantrum, making 20 videos about it, threatening lawsuits. Come on man think for two seconds about the potentIal ramifications of you doing this. It's disgusting behaviour and you should be ashamed to steep so low, for what? To get ahead of a video he *might* make? If science is on your side why would you resort to this...
Seems fair to me. If you stand up and publicize yourself, then you are there to be shot at. Cannot blame ZFC at all. I for one had never heard of this guy before, so all information is well received.
1. Where's the evidence that Absolute Black employees are responsible for the site in question? 2. Is the information on that site true or false? 3. Does Hambini have a responsibility to represent himself honestly when it comes to his CV and technical credibility? 4. If the stuff on the aforementioned is true, what does that say about Hambini's analysis of anything? What does it say about his slagging of aero claims? It's worth noting that Reynold's numbers for turbine blades in operation are a few orders of magnitude greater than those of bike rims and tires and bike frame elements. 5. A PhD in science or engineering implies knowledge of how to criticize someone else's work. Given that, why hasn't Hambini contacted ZFC to discuss questions or concerns with ZFC's processes and data? It's worth noting that when ZFC has such questions about claims, data, processes, et al, those questions are asked of the manufacturers. Hambini's refusal to do as much certainly raises doubt about his PhD, doubt which seems justified by the above website. How do you feel about the junior high school level slagging that Hambini relies on?
oh and sorry one last point - you say if science is on my side why would i resort to this? (And by this you mean me highlighting VALID questions and concerns...) - we sadly live in an age where facts rarely matter. To cult like H fans, no matter what he says and how i counter- it will be gospel truth by him, and yeah right re anything i present back, no matter how concrete. Like i mention in the vid - for far too many emotional thinking rules, facts apparently can go fish. If facts actually counted - then we wouldnt have politics like we do in the world, or debate about climate change. there wouldnt be abject corruptions on supreme courts, and congress share trading. Or major companies bankrupting the tax payer. Or i could type for about 3 days. So, sadly - facts will count i think a lot for ZFC followers. They will count for near naught for a lot of H followers, same as facts can go F themselves for Durian rider followers - many of both of those just want the drama, they want the bullying, they want the "take down" even if all the info in the take down is made up - they dont care, they are happy to just run with it and go yeah - look at them holding accountability to the industry! Not caring at all they are being made as suckers as they have no idea when what is being present might be factual, or just outright made up. Alas - science and facts doesnt save anyone from the likes of H or D. If it did, i wouldnt be on the receiving end of anything from them other than good referrals to zfc for the best information in the chain lubricant space.
I gather you think im the latter? let me know what i am being contrarian about and how, and whats click bait vs substance - that will help me understand your thoughts
It's worth remembering that being an engineer or scientist does not make one's claims true. Empirical data is needed to prove claims true. Curiously, Hambini's videos are curiously free of data. Yes, when he measures wonky BB shells, he provides measurements, but beyond that he doesn't really provide any data or even any hint as to how he calculated his "values" or came to his "conclusions". It's also worth noting that doing a project on the aerodynamics of jet turbine blades (high Reynolds number) does not make one an expert on the aerodynamics of bike wheels and tires (low Reynolds numbers). There's a reason why bike wheels are tested in low-speed wind tunnels and jet engine turbine blades aren't. That all begs the question: if you're a real engineer and you provide zero information about any calculations done and the assumptions made while doing so AND you rely on playground insults, should anyone give what you claim any credibility at all?
@@robinseibel7540 that is all most brilliantly said. Just you wait for when i cover his steel vs ceramic bearing test, and how that went when i asked him, very nicely - for more information on that test. And then we have a veritable orgy of evidence against that "data" being correct. And to say there are questions about the aero data by - and lets just say i am on a highly populated island on that one - is an understatement. The sheer amount - at what cost, (how is that being covered) and the amount of time, by multiple people needed, and where and is it suitable, and what protocols - and ooh this is just the entree. It astounds me that he is lining me up to question what i have no idea - when all of my test protocol is open, when he would have to know that rather than me start drama - it just gives me the green light to rip of the band-aid of tip toeing around doing vids on good bearing information, hints and tips in case it triggered Mr H. Im not sure how he thinks this is all going to go, but my mantuition is telling me it aint going to go how he thought it would when added that part to his vid last week. Going to be interesting what he tries to make up re me, but no one has to make up anything to ask a lot of very good questions re his "data" indeed. And correct speaking of qualifications. You should see a recent vid by sabine hossenfelder covering the extreme inaccuracy and embarrassment being brought to the scientific community by a nobel prize winning scientists absolutely whackadoodle climate change theories (which he poses as obvious fact). I cant include link here as YT will delete comment. Oh and also over the last decade the nobel prize winner john goodenough (now passed away) - inventor of the lithium ion battery - high credentials indeed - well, lets just say there is a fair bit of continued issue around his work in his later years on a glass battery that would break the laws of thermodynamics. It is still being worked on and so maybe we will all be proved wrong - but its not looking grand at the moment; "The initial publication in December 2016 was met with considerable skepticism by other researchers in battery technology, with several noting that it is unclear how a battery voltage is obtained given that pure metallic lithium or sodium exists on both electrodes, which should not produce a difference in electrochemical potential, and therefore give no cell voltage.[3] Any energy stored or released by the battery would therefore violate the first law of thermodynamics. Goodenough's high reputation was enough to deter the strongest criticism however, with Daniel Steingart of Princeton University commenting, "If anyone but Goodenough published this, I would be, well, it's hard to find a polite word" A LOT of money has been invested based on his credentials into glass batteries - i wonder if they are expectant of an ROI.. So as you say, qualifications are one thing, but all work presented must stand on its merit, and be open to scrutiny. Judging by the response to basic questions in the past, i would say open to scrutiny is not Mr H preferred way of operating
@@zerofrictioncycling992 , I do not understand how he responds to criticism. In grad school, we were questioned about our assumptions, our methods, and our data and the analysis of that data. Sometimes it could be harsh, but none of us got in a huff about it. Instead, we took that criticism onboard, and then we revisited our methods, assumptions, and analysis. That's how science and engineering go. It's not a process about pride but rather it's a process designed to get reliable data from which we can make justified conclusions. That's how we advance our knowledge and tech. When pride gets in the way and when people start assuming that their status gives their claims credibility--like that Nobel laureate--well, that's when things go awry. My office in grad school was two doors down from a Nobel laureate in physics. He was a nice man, a humble man. Contrast him with someone like Hambini who seems to have some pathetic need to criticize others and feel superior, all while using his "CV" as evidence that what he's doing and claiming is unimpeachable. He's got issues.
Shit no. There’s yourself Josh and Leuschertech (forgive my spelling) on the side of reasonable fact based conclusions. And then there’s the everything’s shit there all against you populist dickheads, Hambini, Durianrider and Oz Cycle.
ah sorry looks like maybe an editing error in my rush - i put a clip in twice and missed the lead in clip! Have i mentioned i am terrible at YT and social media...
3 years going with an emersion waxing my mtb chain with no perceivable wear. No greasy marks on my leg. No expensive degreaser and still on the same silica wax.
Let the haters hate!!
it is such a strange thing to hate on!! I totally get that if its not for someone, then fine - all groovy and normal. but to hate on that option for others to enjoy the benefits - thats just whackadoodle land! Strange hill to fight from.... but it is a strange ol world these days..... Many things make me feel very sane and normal which is nice hahahahaha
I bought the Abbey Tools chain wear tool and found closing in on the last quarter my first season across 3 T-Types no measurable wear either.
@@justinfournier1285 Love the Abbey chain tool, but it looks like it's a bit of a waste of money. With no chain wear, who needs it?! Then again, the tool can be used to confirm all the bonuses of immersion waxing. And with all the money you'll save on chains, cassettes and chain rings, might as well splurge on the Abbey Tools beauty!
The other day I did my first immersion waxing of my MTB chain (aux bain Marie with plain candlewax (parafin)) and it performed awesome. 358 km in a week of (dry) gravel without a hitch. I did add squirt lube at the end of the week (after 300 km) but I doubt it was necessary.
Thank you for showing me how easy it is.
One of the biggest reasons I went with Shimano 12speed mechanical grx was cost of ownership.
I’ll keep testing to the .5 wear point. So far I’m hitting over 10,000km with hot wax with little to no wear. And the chain rings look great.
Love to hear it!
In my personal experience…
Expect a lot of insults and a lot of lies from Hambini.
Hambini is 100% a cult.
hahahaha yes indeed! oh my lordy it is going to be something alright, but..... its ok, for all the abuse soon to be coming my way, i might be able to open the eyes of the not yet scientologied followers. There are still those with functioning thinking brain out there in his followers vs just H coolaid cult followers where the ability to actually assess any information on merit has left the station awhile ago...
your situation was pretty nuts. But hold my beer - wait to you see this all unfold!
Did you see Cyclowax were testing an on-bike immersion wax machine at the TDF? Can't post link because YT... article was on bikeradar "Spotted | Lidl-Trek using prototype automatic chain waxing machine at the Tour de France".
My guess is it might work for this specific scenario - where the chain will get re-waxed frequently. But probably won't be as good as traditional potting.
At 30 minutes per chain, it definitely is not as efficient - I mean couldn't the mechanic remove, immerse, dry and re-install an entire team's worth of chains in 1 hour?
Curious to know what you think of this, maybe you could tell us in this week's vid?
Yes indeedy - that is something for sure. Whether it proves practical / of benefit or not - i am yet to be convinced, but i will always give kudo's to small new player like CW having the courage to invest and try to drive innovation in a particular space.
There would be quite a lot of hurdles for that product- i actually think the hurdles are much bigger in the pro peleton that a fancy home workshop set up / user. A pro team would need a lot of them, and thats a lot to carry round, and they are no doubt pretty expensive, and especially until absolutely dialed and reliable - could there be a risk one didnt do what it was supposed to have done and left a rider on a big stage without a lot of lubricant. Pulling ones chain out of the wax pot after swishing - one knows what they are getting.
Vs say popping circa 10 chains off a bike (10 mins), and putting 10 chains into a large pot to re wax all at once, then re install after set - would that be more labour time than getting 10 x bikes into wax machine? what maintenance does the wax machine itself need etc etc - but - who knows - like all v1 products maybe this one is a bit clunky, but the learnings from this one mean v2 is a lot better, and v3 rips. There is only one way to go from hmm im not sure to oh baby you rock my world and that is to have the courage and drive to get v1 out there, so i really like their innovation, investment and having a grand ol crack - im not personally convinced yet, but i am open to be, and i wish them every success.
I have spoken to CW a number of times on a number of things over the last few years and they really are very passionate about the customer and customer experience, so as a company i like them a lot and i think overall they made a lot of great moves already with training wax and race wax tablets, the pot and stand that was copied to a large degree by silca (a big player copying you is a good compliment!) and more.
@@zerofrictioncycling992 Thanks for your detailed reply! Very good points about innovation etc. Let's see.
Shot for the stars! You can put your focus on the hour record - in the 105-110 bracket!
Yep my plan at the moment is to dominate master 10 category. Hence i am currently carb loading and putting on some kg's for my "strength building" phase - which is planned for the next some decades to get proper strong ready for the "complete and utter domination phase" in my 90's and 100's.
I've found most people only have 5 year or 10 year plans. Suckers.
I added a comment to Hambini’s video saying ZFC does not deserve the criticism or regular abuse from Durianrider. But he deleted it.
that sounds on point. Maybe keep that window open and re add it each day hahaha
smh I remember reading it.
Poor old Durian... struggling just to stay relevant
The Reginald Scot vid " Hambini Wants To Fight Me! " says it all ! DR might be distracted now with the ultimate narcissistic act ? Maybe he's trying to be the Ron J of the cycling world ?
@@clintmichigan9112 He lost me a long time ago because of lack of relevance. I heard his message but it never got passed all the rants.
Well done on the 300 and great video
DRs whole sub base (and the world) bursts into laughter when he states he coaches world tour riders, any riders for that matter.. Cant imagine Pog getting on the phone to talk sugar water, rim brakes and only fans porn while getting ready for the tour. 🤣🤣🤣
A few Halo observations that don't need an answer, please read with a very sarcastic tone. Let's hope you get some answers soon until then. Here is a comment to up your video engagement :)
Since Finish Line would never put abrasive additives in their products I am doing a mental run of the single application longevity test. Let's take the Halo drip lube in block 1. I have read comments on your videos and you have said that the wear is pretty even through the block. That would indicate that drip lube would hit the 20% wear at 100km. You then divide that number by 3 to get the real world adjusted wear rate jump point estimate. This leaves the clean dry conditions adjusted rate at ~33km for 20% and 167km for 100% wear. Finish Line should take that kind of data and start marketing it. Can you imagine the TRUE statement "A single application of our lubricant will last the life of your drivetrain."
I might have to take some of this testing into my own hands. 167km seems like a reasonable distance for a normal person to check in the real world. I will get on it when my current chain wears out. Currently my hot melt waxed chain has ~4000km on it, and my shiny new Abbey chain checker says 0% wear. Thanks for the recommendations, Adam.
I believe you did not take the testing far enough. I am quite sure that block 4 is where this "lubricant" would shine. I believe block 4 performance would have shown better performance than block 1. I am sure that the cleansing effect of water and dirt might remove the additives causing the issue. The block 4 improvement would be a positive test result for Finish Line. You must really have a grudge with Finish Line to not continue the testing. That would mean that the Halo products may have been the first lubricant to improve with contamination. Can you imagine the marketing Finish Line could put up around that claim.
Ha that is all very good!! If we dont get to the bottom of things, and re test when i get my hands on more commercially obtained halo if things are still similar i may check with you re royalties on that marketing line!
On re test i will consider going well past the normal 0.5% stop point (i did with the drip wax, that went to 1% just in block 1 anyway omg) - but will depend a bit on how many tests banked up and also at a point it does get risky, and if we have already assessed that a product is bad there is just not too much point using valuable test time to keep confirming what we already know -but.... maybe if it is a truly historic wear occasion again like testing round 1....
Thank you for the work you do.
It's amazing that the industry still makes so much garbage product and the bike shops continue to stock and sell it.
Edit: I just subscribed
thanks vybekat!
Good on you for your (fairly lofty) fitness goals! I wore out my resolve over nearly 40 years of road racing, with only mediocre shading to barely competent results (2 years in club/combine A-Grade/regular open racing was enough for my sanity & overall health) to show for it. I enjoy touring and gravel riding much more now, with only the next hill to conquer, and the next view to enjoy. I still like riding my road bike, but won't compete on the littlest hill, nor the most insignificant town-sign sprint. I've just lost the desire to 'beat' people. It's a phrase with aggressive, public-school rugby-playing roots.
I do barely any road racing these days although that was where i started - but i cant sprint worth a damn (i might be one of the first people whose sprint and FTP are nearly indistinguishable) and so dropping wheel suckers who can sprint, who dont work or when they do their turns its worse than if they just kept wheel sucking (ie - the crystal shoes syndrome) - and in general the road race scene - at least it was here - is generally pretty tense. its like most people and officials have done a course on how to be / act / seem more tense.
The mtb / gravel / cx scene is just SO MUCH more relaxed and really friendly. I dont do it for the competitive aspect at all - its still fun if i jag a decent result, its still fun if i am miles off. There are just lots of cool friendly peeps out there been now racing with for years, often the courses are great, and its just a fun morning / day out.
And with gravel theres groovy events that many dont race at all, they just use it for a grand ride day with friends or solo supporting a groovy event - so even for the least competitive, some of those are worth a look just for fun! But of course if one is enjoying how they are riding, stay the course- one persons pleasure can be anothers nightmare. Ie i have friends who love crits hahahahaha
How do you clean/reset the drive chain between tests, i.e. to prevent previous lube/contamination getting on to the next chain?
everything is replaced in almost all instances - so new rings, cassette, pulleys (clean mech cage) and of course new chain. The instances where this is not done are if just testing similar base for mfg where we are doing much shorter tests (ie just block 1 vs full test or just one part of single application longevity test)
@@zerofrictioncycling992 wow that's amazing... And a lot of effort/cost.
@@Lacking_something yes its also part of why the testing isnt cheap for paid private tests (although labour time is the biggest cost still by far), but it does add up for little ZFC for the tests done for open knowledge / league table.
@@zerofrictioncycling992 Yes, makes sense you would have to and I have also wondered about this (Inc bottom bracket, and trainer calibration too I bet) So many parts...no wonder you have your own shop. You need accurate comparisons and I bet some of the companies that haven't performed well would be looking for reasons to discredit results.
@@colinl2908 Bottom brackets thankfully last AGES. And i mean 100,000 / 150,000km + ages - things are just much less stress for motor driven vs pedal driven - so BB's are easy. Freehub bearings are the main maintenance as they take pedalling load (chain load in this case) and are small bearings -but i remove the spacer and run 5 of them vs 2 so get much longer intervals otherwise they need replacing every 2 to 3 tests vs circa 10 tests.
And yes some do - but very quickly find they simply have no way to do so - the chain is simply being run on a bicycle drivetrain - and so to date no mfg i know has raised anything against the zfc test.
Btw, update on my fully refined paraffin wax: going to re-wax tonight after around 200 km. I think it could go another 100 km, but I have a feeling it would benefit doing it sooner rather than later. The new chain I started with is a cheap one (brand named Fluir from China). I went with 4 or 5 turps baths and 3 meth baths to be safe, but not sure it got everything out. Thinking of getting another chain and adding stearic acid to the wax and seeing if I can do a diy version of Silca's grease converter blocks.
It would be nice if commenters could add one bit of crucial information: road or mountain?
Pretty big difference between the two. Knowing how bad conditions are where I ride, I'd expect a road chain to last 5X to 10X the miles of a mountain bike chain. And a track chain? 20X+! But that's a totally unsubstantiated guess.
Either way, please specify!!!
@@dudeonbike800 Sure - the answer is neither! I guess road/track is the answer you're looking for; I only ride on the trainer because riding on the road in South Africa is suicidal. Trainer and bike are kept on a balcony and a bike cover is placed over them when not in use to reduce exposure to dust.
The trainer is an Elite Suito.
On the trainer I'm currently doing 'moderate' rides for an hour, trying to maintain 125 watts. Sometimes I'll throw in some 1 minute intervals at 200 watts.
I'm also not sure I needed to re-wax so soon. I wasn't hearing any squeaking or grinding. It just 'felt' like shifting wasn't as smooth as it should be - but still totally rideable.
I kind of enjoy the re-waxing process and my hands stay clean through out. So really don't mind doing it once or twice a month.
The initial waxing is much less enjoyable, hence the curiosity to try stearic acid to reduce the amount of solvent stages for prepping a new chain..
I'm also running a relatively cheap drive train (Shimano Claris) and as mentioned a cheap chain (Fluir).
Since it's under $10, I've ordered a second chain to experiment with. Jury is still out on how long it lasts (regardless of lube).
Hope that was specific enough.
@@avibank thanks for that. I'd classify you as "track."
Just saw a German drivetrain brand called Enduo with some pretty wild claims that their chainrings and sprockets double chain life. Most interestingly they miss out every other tooth on the chainring! If it works then great.. but I can't help be feel a bit sceptical about the claims. I would love to hear you discuss this product and potentially test if its really a wonder product. They are actually offering samples.
yes that one is fascinating. I have had a chat with them, and it is possible they may look to book some testing to prove the increased longevity of chains / parts of that system.
I dont want to shoot down any of their theories without a) better understanding and b) testing - however on first blush i do have, lets say, some doubts. I did run through some of the questions / doubts on the call, but i admit i was not able to get to an understanding of how their theory and system workings would improve longevity - but it is of course possible i simply lack the ability to understand their concepts.
As i have a simple brain, some things i just keep bringing back to basic principles. The pedalling load must be taken by the chain. The load is going to be transferred through the link plates and pins, and these parts are going to move against each other as they articulate under load causing wear like all moving parts under load. If you half the number of links, you would essentially double the load on the ones remaining. They are aiming to counteract that load by locking it in the from the opposite direction as well from the pedalling force - which is a novel idea - but i struggle to grasp that we have directional load pedalling the bike forwards that is effectively locked static between the teeth / links on the ring and cassette. I think i get their theory / approach, but when i run that through watching the vids - it is just not how i see it playing out. If it did work, there would such a massive longevity jump as they have effectively neutralized the load on the moving link parts that it would have already been extremely easy demonstrate, and it would certainly be easily demonstrated in testing here - i would simply run one chain with control lube on normal chain ring and cog, and repeat with new chain same model same lube on Enduo, and see a very very big difference in chain lifespan. This is something they could have already easily replicated the resources to motorise a smart trainer are pretty small, and a drop compared to what has already been invested. Considering how such a night and day test result would help their marketing, i dont know why that hasn't yet been done. Quite a number of lubricant mfg's now have test set up same / similar to zfc for their own in house testing - it really is a low capex bar for mfg to verify performance - i must say the lack of this at this time is confusing for me.
If i was me and i was looking to compete in the segment they are trying to compete it (which is largely vs belt drive) - as their chain system is single speed with hub / gearbox for cargo / commuting - I would simply go big. Increase the chainring size and corresponding cog size to the largest practical so that rider load / wear load is spread over as many links and teeth possible which will reduce load per link and tooth and also across a greater number of teeth and links for a large jump in wear life, and you also get an efficiency bump vs smaller. To me that is a vastly easier solution and one doesnt need proprietary rings, cogs and chains. Such a system with sram hardchrome treated chain - that is going to go far, cheaply and easily.
i had plans to cover this briefly in a low friction news update - maybe this week now you have reminded me - but hope the above helps give you some extra thoughts on the system on top of your own
@@zerofrictioncycling992 Thanks for the detailed reply. Your thoughts are pretty much along the line or what I was thinking too. A related thought that just crossed my mind whilst reading your reply is that chain wear loads would be most reduced if it were possible to avoid any articulation of a chain within the section under load. In reality this would probably be very mechanically complex to do, but running larger cogs would reduce the amount of articulation needed as it wraps around the cog and therefore reduce the wear. I imagine that 10 tooth cassette cogs must wear the chain significantly more than even 11 or 12 tooth ones as there is an increasing large articulation within the chain under load as the diameter reduces. It's an interesting topic.
@@andyarchitect Yes its been well tested and covered by the likes of jason smith in the past and its why we see for TT's such massive chain rings being used as they are watts more efficient.
Basically we have 3 aspects all adding up. Larger chainring = less chain tension for a given power. Ie the tension load in the chain for a 170mm crank on a 32t chainring is much higher than on a 60t chain ring. With a 60t chain ring the torque / leverage loss at the crank you gain at the back wheel with a correspondingly much larger cog for the same gear inches which has greater torque leverage to turn the wheel. And of course power = torque x speed = a 60t at 90 cadence has a much greater chain speed - so lower torque / tension in chain x greater chain speed = 250w power is still 250w power - but with a large chain ring and cog, that power is transferred with much lower tension load in the chain.
And then the chain is articulating less at the chain ring, and for a given gear inches, articulating less over the larger rear cog. So we have less articulation, occurring at lower tension loads at both ends of the drivetrain which is a) more efficient and b) less wear. And then for this case we also have that wear being shared over more teeth on both ends, and likely more links of a chain as longer chain.
So for race bikes larger rings is done for efficiency, but for the commuter / cargo space - it should be done for parts longevity. There might want to be some design tweaks perhaps on some bikes to enable much larger than current typical chain rings and cogs - but surely that has to be an overall simpler and easier path vs a proprietary new rings / cogs / chain with longevity extension physics that are going to be to most .... i have to take your word for it that it works like that. With big ring / cog - the basic mechanics / physics of torque / tension, lesser articulation, and more parts sharing the lower load - that is easy for most to understand in about 60 seconds.
The reality is simply a cargo bike with a gear hub moving from a 40t ring and a say 17t cog to a 60t ring and (without using a calculator) i am guessing approx 25 to 28t cog is going to see a significant jump in wear life of all 3 components. If i was me and i was enduo i would be making enduo cranks matched to enduo 60t chainrings made from tool steel, and enduo tool steel cogs, and using sram hardchrome treated chains. They would have amazing long life cargo drivetrains, and i think a much easier sell as this basic physics is a) basic and b) absolutely simple reality of larger vs smaller for potential customers understand and enjoy.
I think their path is problematic on many fronts re attaining commercial success. If they dont gain sufficient market traction - sooner or later seed capital investment funds will have to run out. So now if i was them and all they have invested, i would do both - stay the course with the theory, but make the big. At least one of things going on will absolutely give the customers a great longevity boost, and if both do, yeehaa
@@zerofrictioncycling992 Good points there. I hadn't thought about the fact that a larger rear cog will reduce the tension on the chain due to the extra leverage. You made some really sound points there for increasing durability of a drivetrain. Seems like Enduo may be reinventing the wheel without addressing all the basics first. Maybe you should change for consultancy work on this topic 😄
@@andyarchitect Ha! yeah i do the odd bit of advice indeed to some mfg re lubricants, but for companies like Enduo - if you are stepping into the space of innovating bicycle drivetrains - the above is pretty entry level info really, i feel certain they would have to be across all that as its been covered for a good while and to an engineer that would all be very obvious.
However my guess is that it is simply to basic and boring a path to base a new exciting start up business on and get investment capital. A revolutionary new system like Enduo stands them apart as an exciting new innovation to drum up investment etc -where as just "umm - shouldnt we just go bigger?" it is unlikely to get any of those who like to invest in exciting new start ups heart racing. Alas even though sometimes the solution is obvious, its too boring. If you want to be an entrepreneur and launch an exciting and innovating new business in a space, you need something that looks exciting and innovating. Sometimes a products performance matches that, and sometimes..... its just all fluff and a dud vs much simpler and more obvious paths / solutions.
Which one enduo really is will be exciting to find out one day if we can... But yeah - if i was me, i would just go bigger. Or if enduo's works as marketed, i would do that as well as go bigger :)
Hi Adam... Or Hambini fans. Before I watch this video. I have to tell you, Hambini is not living in China carbon composite industry. He called himself an engineer, but he don't know too much about composite materials.
After his service video, he blamed bolt stuck into the top cap as top cap being threaded 😁byha makes no sense.
I feel that what Hambini is is a rage merchant. He seems to appeal to people who mostly hate everything about the sport and industry of cycling
That button is distracting me !😢
sorry mike what button? i will try to un distract next video!

Great information as usual, Adam. Congrats again on the 300th race. It really is astounding. And 2nd place at that! Well done. I also appreciate a little of your background. I find those things interesting.
I followed Hambini for a little while several years ago but had to unsubscribe just because of what I consider to be a toxic personality. I know a lot of people like that and everyone is different. As for me, I just couldn't take it any more. I'll just see this as an opportunity for you to get even more good information to his viewers.
Very much the same for DR. I watched several of his videos early on, mostly looking for vegan cyclists, but stopped fairly quickly. I can only speak for me, but I don't think you need to talk about him unless you need to defend yourself. Giving him any more oxygen than that just serves him. It's not worthy of your time. I sure don't need to know about it. That said, if you feel like it's important to bring up, then definitely do that. All of that said, gross.
Have a great weekend my friend.
Thanks Cat! And ha yes correct i mostly try to avoid DR as despite the temptation to counter so much of his made up attacks on me / zfc - it does just give him what he looks for. But that news was just too omg to leave out, especially following on the from imminent H update as i believe those two are pretty buddy buddy (birds of a feather flock together as they say.... - i imagine both are graduates of Andrew Tates Hustle academy).
Strange ol world out there...
@@zerofrictioncycling992 Strange ol world indeed!
Sram solution to slow sales is to shift the point recommend max wear for their chain's.
ha yeah maybe, it is honestly not the best path to follow if we dont want to eat out some expensive and magnificent cassettes and chain rings, so it will be good to get the official thought paths from sram!
Added to the probability that SRAM wears the most, when you consider that campagnolo wears in, where shimano wears out, and campagnolo is the least popular- I use all 3.
@@richardhayward4537 Hmm tell me more about campy wearing in..... with regards to chain and drivetrain component wear - campy is not setting itself apart in any way as the parts are subject to the same challenges as all others. Their chains have very normal wear life, and same with cassettes and chain rings. From a chain / cassette and chain ring perspective, they most certainly don't wear in as others wear out. In fact there are some overall issues re campy in general such as....
> Their stance for a very long time against master links and removing chain for proper maintenance, in general leading to increased wear rates vs chains where the mfg is perfectly fine with you removing chain for waxing / proper flush clean maintenance.
> Products that really benefit from such - as in ekar - the master links are $29.90!!!! And one really wants to keep the chain low friction and wear due to the cost of ekar cassette...
> the super slick cabling to keep 12 / 13 spd mechanical systems shifting well again costs north of $100 aud, and like all cabling if used for normal volumes should be done circa annually.
i could go on and on (such as the waste of including a 123 page instruction book in EVERY chain - have they not yet heard of the internet - what is cost and waste of that over say the last decade?) why do their eps batteries cost many hundreds when they are essentially exactly the same battery as axs which cost circa $100 - and yep - it never ends, and its all this stuff where they do not understand that it is simply driving them to probably be smaller drivetrain mfg that TRP in the future from what was once sheer market dominance. You dont go from market dominance to concerns of death whilst competitors grow ever stronger from great decision making and products. They have trended to where they are due to poor decision making, and a difficult prices to justify for comparative performance.
I really want campy to live, and oh man i really wanted to put ekar on my gravel / cx bike - but i just couldnt, it just didnt / doesnt stack up to the competition - again, and things like $30 master links and $100+ cabling just means that i have to shake my head and sigh sadly, again, and go with a competitor...
@@zerofrictioncycling992 tour of timanfaya
I used to work in a bike shop for a few years and learnt that campagnolo lasts so much longer, it was common for people to say campagnolo wears in shimano wears out, from middle aged cyclists and from the shop itself from colleagues. One thing you didn’t mention is the structural molecular build of campagnolo materials. I have 10 speed that I’ve had since 2010, I use 11 speed shimano ultegra and reluctantly recently bought a BMC 01 road machine with sram force (I bought because of the frame) at a great price. Using KMC chains is probably just as good as campy, but the other parts should outlast by at least twice. It’s a shame that campy has gone full EPS with no other options, but I will still persevere with 10 Speed and I’ve been getting some real bargains on eBay with chainsets I’ve recently bought, £70 for record chainset, and £100 for 11 speed SR(cross compatibility with 10 speed), hardly used condition. I can’t, for the life of me, imagine that campagnolo would downgrade the molecular construction, unless shimano and SRAM would up their materials, I suppose you could compare equivalent in 10 and 11 speed for lastability, and when you mention SRAM chain wear checker is only measured past worn point you can see their intentions.
I cannot comment on 12 speed eps as I don’t have one, but may upgrade in time. I think campagnolo will have to change again because they have narrowed their own market which was already a niche one.

Interested to see what Hambini says as it's hard to debate facts. I watched a few of his videos a couple of years ago, but his shock jock style/banging his hairdresser rubbish put me off.
The end of the video 😂
Just watch Hambini's headset replacement video to see how much of a hack he really is. Also Hambuni wouldn't know a thing about testing protocols. Josh at Silca in one of the marginal gains episodes (cant remember which one) proved Hambini could have never done all that aero wheel testing he claimed to have done. Might be worth having a chat to Josh to get the specifics for any response video 😜
thats a good idea thanks! Yeah he has a pretty massive amount of aero testing, which aside from the time and huge cost (who is covering that?) does seem rather difficult to do from ones lubricant factory.
@@zerofrictioncycling992 in the meantime if you want a laugh
th-cam.com/video/FTwa8Q9UVh0/w-d-xo.htmlsi=UwlH--qQwU14WQL6
Why is Finish Line still in the focus? Even last week it was too much already. You just giving them more publicity
sorry feedbackloopz if you feel that way - but yeah it is all quite extraordinary re a) the claims and tech apparently being used and b) the test results - i mean we have a latest gen lubricant and IM wax that appears to be actively abrasive as the wear rates are worse than no lubricant, something i never thought would see really.
So it is all rather something in the little focus of lubricants, and i want to give FL the best opportunity to help us all understand.
As i get further info (ie call with FL hopefully next week, the analysis results from the science lab, re test when i can get more product) - it will continue to be followed up and updates covered for a little bit yet i think - but if not of further interest it will be time stamped so you can skip it :)
@@zerofrictioncycling992 oh no, I will definitely not skip that part when they come up with some new excuse or unrealistic claim ;)
I mean, it's your time and your channel after all, you decide how to use it
Is it any accident that SRAM are erring on the side of sloppy with their 0.8% replacement recommendation for chains, in the same little while that they have released the Red AXS XPLR groupset, the cassette of which retails for USD $649 (AUD ~ $1000!!!)? Which, if you don't wax and swap the chain (USD $70, AUD $130-150) regularly, and replace it/them at 0.5%, could have a lifespan as short as 5000-8000 kms? Who am I to question the wisdom of hegemonic US corporations, and their fleecing of impressionable idiot MAMIL/MAMIBs, with my mechanical 10 speed SLX/old Dura-Ace/Ultegra/Stronglight cheap-as-chips mullet gravel/CX/ghetto-trash drivetrain?
yes this is the very big concern, and honestly a chains performance itself starts to really deteriorate after 0.5% (refer silca velo vid on chain stretch done recently), as well as just guaranteeing will need new DT components. Yes their hardchrome chains are very wear durable, and yes their chain rings and cassettes (most models) are also hardy and wear durable - but 0.8% will simply ensure they are eaten out too much to take another new chain.
And - as durable as their hardchrome chains are - that is still no match for how poor many commonly sold lubricants are by some big name brands - the ones most often stocked by LBS.
So it can be big, big ouch basically annually for many - which is not cool.
This call is apparently going to happen (not sure if this week....) but trust me i will be going hard on the above to get their take / reasoning!!
"All information contained on this website are fans’ personal views and/or findings that were collected over time and are not scientifically validated. "
HAMBINI might be a liar, or not, but sharing links, to personal pictures, and shit.... its stupid sad and coward.
Sad very sad
sorry you feel that way alves - and i do get your concern for sure. Alas - i have someone with a cult following who is no doubt about to make up a whole lot of shite about me/ zfc. I hate bullies and will stand up them. I hate corruption and dishonesty and will stand up against that. If in this case it means i have to glove up and wade into the shite, i shall.
If a dishonest bully is going to maliciously make up shite to attack me, i aint just going be bend over. People should be aware as a start re SOME of the concerns of H, which will help me when it comes to responding to a malicious bullying attack.
I would first ask why that website exists in the first place, and then ask who is the bigger victim - H, or the followers of information presented as fact and believed as such.
If you disagree, i understand - not all will be agreeing with me on this, but... i reserve the right to defend against such an incredible internet bully of rather questionable honesty with all ammunition available to me.
You and Hambini do have a few things in common. The best thing is that you both want the best for the consumer. Calling companies out for failing on this.
Thanks mark! And yes it would be brilliant if things could have been different - ie you see how shane miller and DC rainmaker both help make the cycling information space better. I was really surprised, and very disappointed - when years back some basic clarifications on the steel vs ceramic bearing test and information were so quickly met with some rude words and to basically go F myself. I am sure outlook still has the email chains i can publish if i feel the need in my response. And simply since that i was on the shit list. Which i admit, i didnt help when for his initial years i found a number of his videos quite shocking re a) what i felt were very misogynistic, and b) just simply extremely bullying and very personal attacks on people. These video's are now deleted - he deleted i think about 2 years worth i think to keep his channel, as many of them really were just..... well there is highlighting concerns, or difference of opinion, or calling out - and then there is just flat out massively abusive bullying for shock value - and that is very much not me, and so when someone would link me with hambini - i would comment to the effect of please do not do that due to the above. This will have no doubt moved me much further up the shit list.
But im not sure if you remember the one he did on xavier disley at aerocoach (who mind you has since proven very correct vs H re his aero work and products). H was SLAYING him abusive, calling him Mr Vagina Head, and probably out there riding a "Fat bottomed Womens bike", as well of course as the never ending use of the C word. One could say clever marketing to build channel through sheer shock value and drama - as well as of course generating as many lawsuits as possible again for shock and drama for channel growth - lets just say we are very different characters. And i think that approach attracts a lot of a certain type of follower, and they are not necessarily using their thinking brain, but will jump on ANYTHING he says - whether or not on that particular occasion it is merited. If he is annoyed by a product or company - his personal opinion is presented as fact, and very attacking, and people / companies are then on the receiving end of abuse they do not deserve.
Going to be fascinating what he attacks me on, i am obviously going to be seen as biased here - but aside from being an overly verbose terrible presenter / talker on YT - i just dont know what about me / zfc there is to attack unless he is going to go durianrider style and just maliciously make shite up. We shall see! :)
@@zerofrictioncycling992 some really thought out points raised. I'll think I'll look at the points raised.
@zerofrictioncycling992
Shane and DC should be almost compulsive reading. DC really does go into alot of detail writing his reviews up.
Since your review on Muc off I binned their products and haven't looked back. Waxing is so much better.
Keep on doing what you're doing 👏
"The boss has been on leave" give me a break. If your business is at risk, you reply (at the very least) asap. Will be so interesting to see what they say. Any update on the lab tests?
ah its ok - i get if on annual leave you go work incommunicado. FL wont be at risk due to little ol zfc having concerns - they sell around 20,000 units a month of FL dry just on amazon alone - they are doin alright thanks to legacy brand name (and remember from that they have massive penetration into LBS).
And not yet - i have a feeling it will take awhile - it should have arrived there this week / early next week - so will start chasing up results in another week or two.
I will hope to get the next call with FL this coming week though if possible and see how i go understanding these tungsten spheres and also what questions / concerns they have re zfc test.
I am incredibly disappointed in you for linking in your description that Hambini doxxing site created by AbsoluteBlack employees. How would you feel if the same if Finishline etc was equally upset with you for a negative review and decided to hire private detectives to follow you around taking pictures of you going to work in some petty attempt to discredit you and then referenced by other content creators on youtube who disagree with you. I'm sure you would be throwing a tantrum, making 20 videos about it, threatening lawsuits. Come on man think for two seconds about the potentIal ramifications of you doing this. It's disgusting behaviour and you should be ashamed to steep so low, for what? To get ahead of a video he *might* make? If science is on your side why would you resort to this...
The question is are the informations on this site all lies ?
Seems fair to me. If you stand up and publicize yourself, then you are there to be shot at. Cannot blame ZFC at all. I for one had never heard of this guy before, so all information is well received.
1. Where's the evidence that Absolute Black employees are responsible for the site in question?
2. Is the information on that site true or false?
3. Does Hambini have a responsibility to represent himself honestly when it comes to his CV and technical credibility?
4. If the stuff on the aforementioned is true, what does that say about Hambini's analysis of anything? What does it say about his slagging of aero claims? It's worth noting that Reynold's numbers for turbine blades in operation are a few orders of magnitude greater than those of bike rims and tires and bike frame elements.
5. A PhD in science or engineering implies knowledge of how to criticize someone else's work. Given that, why hasn't Hambini contacted ZFC to discuss questions or concerns with ZFC's processes and data? It's worth noting that when ZFC has such questions about claims, data, processes, et al, those questions are asked of the manufacturers. Hambini's refusal to do as much certainly raises doubt about his PhD, doubt which seems justified by the above website.
How do you feel about the junior high school level slagging that Hambini relies on?
oh and sorry one last point - you say if science is on my side why would i resort to this? (And by this you mean me highlighting VALID questions and concerns...) - we sadly live in an age where facts rarely matter. To cult like H fans, no matter what he says and how i counter- it will be gospel truth by him, and yeah right re anything i present back, no matter how concrete. Like i mention in the vid - for far too many emotional thinking rules, facts apparently can go fish. If facts actually counted - then we wouldnt have politics like we do in the world, or debate about climate change. there wouldnt be abject corruptions on supreme courts, and congress share trading. Or major companies bankrupting the tax payer. Or i could type for about 3 days.
So, sadly - facts will count i think a lot for ZFC followers. They will count for near naught for a lot of H followers, same as facts can go F themselves for Durian rider followers - many of both of those just want the drama, they want the bullying, they want the "take down" even if all the info in the take down is made up - they dont care, they are happy to just run with it and go yeah - look at them holding accountability to the industry! Not caring at all they are being made as suckers as they have no idea when what is being present might be factual, or just outright made up.
Alas - science and facts doesnt save anyone from the likes of H or D. If it did, i wouldnt be on the receiving end of anything from them other than good referrals to zfc for the best information in the chain lubricant space.
i fully agree with that and found that quite disgusting, but he removed the link from the description now
I really like the way there are 2 camps on YT. Real engineers talking with knowledge and experience v's click bait contrarianism.
I gather you think im the latter? let me know what i am being contrarian about and how, and whats click bait vs substance - that will help me understand your thoughts
It's worth remembering that being an engineer or scientist does not make one's claims true. Empirical data is needed to prove claims true. Curiously, Hambini's videos are curiously free of data. Yes, when he measures wonky BB shells, he provides measurements, but beyond that he doesn't really provide any data or even any hint as to how he calculated his "values" or came to his "conclusions".
It's also worth noting that doing a project on the aerodynamics of jet turbine blades (high Reynolds number) does not make one an expert on the aerodynamics of bike wheels and tires (low Reynolds numbers). There's a reason why bike wheels are tested in low-speed wind tunnels and jet engine turbine blades aren't.
That all begs the question: if you're a real engineer and you provide zero information about any calculations done and the assumptions made while doing so AND you rely on playground insults, should anyone give what you claim any credibility at all?
@@robinseibel7540 that is all most brilliantly said. Just you wait for when i cover his steel vs ceramic bearing test, and how that went when i asked him, very nicely - for more information on that test. And then we have a veritable orgy of evidence against that "data" being correct. And to say there are questions about the aero data by - and lets just say i am on a highly populated island on that one - is an understatement. The sheer amount - at what cost, (how is that being covered) and the amount of time, by multiple people needed, and where and is it suitable, and what protocols - and ooh this is just the entree.
It astounds me that he is lining me up to question what i have no idea - when all of my test protocol is open, when he would have to know that rather than me start drama - it just gives me the green light to rip of the band-aid of tip toeing around doing vids on good bearing information, hints and tips in case it triggered Mr H.
Im not sure how he thinks this is all going to go, but my mantuition is telling me it aint going to go how he thought it would when added that part to his vid last week. Going to be interesting what he tries to make up re me, but no one has to make up anything to ask a lot of very good questions re his "data" indeed.
And correct speaking of qualifications. You should see a recent vid by sabine hossenfelder covering the extreme inaccuracy and embarrassment being brought to the scientific community by a nobel prize winning scientists absolutely whackadoodle climate change theories (which he poses as obvious fact). I cant include link here as YT will delete comment. Oh and also over the last decade the nobel prize winner john goodenough (now passed away) - inventor of the lithium ion battery - high credentials indeed - well, lets just say there is a fair bit of continued issue around his work in his later years on a glass battery that would break the laws of thermodynamics. It is still being worked on and so maybe we will all be proved wrong - but its not looking grand at the moment;
"The initial publication in December 2016 was met with considerable skepticism by other researchers in battery technology, with several noting that it is unclear how a battery voltage is obtained given that pure metallic lithium or sodium exists on both electrodes, which should not produce a difference in electrochemical potential, and therefore give no cell voltage.[3] Any energy stored or released by the battery would therefore violate the first law of thermodynamics. Goodenough's high reputation was enough to deter the strongest criticism however, with Daniel Steingart of Princeton University commenting, "If anyone but Goodenough published this, I would be, well, it's hard to find a polite word"
A LOT of money has been invested based on his credentials into glass batteries - i wonder if they are expectant of an ROI..
So as you say, qualifications are one thing, but all work presented must stand on its merit, and be open to scrutiny. Judging by the response to basic questions in the past, i would say open to scrutiny is not Mr H preferred way of operating
@@zerofrictioncycling992 , I do not understand how he responds to criticism. In grad school, we were questioned about our assumptions, our methods, and our data and the analysis of that data. Sometimes it could be harsh, but none of us got in a huff about it. Instead, we took that criticism onboard, and then we revisited our methods, assumptions, and analysis. That's how science and engineering go. It's not a process about pride but rather it's a process designed to get reliable data from which we can make justified conclusions. That's how we advance our knowledge and tech.
When pride gets in the way and when people start assuming that their status gives their claims credibility--like that Nobel laureate--well, that's when things go awry.
My office in grad school was two doors down from a Nobel laureate in physics. He was a nice man, a humble man. Contrast him with someone like Hambini who seems to have some pathetic need to criticize others and feel superior, all while using his "CV" as evidence that what he's doing and claiming is unimpeachable.
He's got issues.
Shit no. There’s yourself Josh and Leuschertech (forgive my spelling) on the side of reasonable fact based conclusions.
And then there’s the everything’s shit there all against you populist dickheads, Hambini, Durianrider and Oz Cycle.
