Wolf Tooth Road Link is an amazing innovation. I'm 71 years old and still like to take my 1973 Peugeot PX10 out on the road every once in awhile. I just can't push a 42 X 26 up the 8% grades anymore and I refuse to get rid of the beautiful Stronglight 93 crankset. I put a Road Link on the frame, and using an the old Campy Record derailleur, I run a 11-36 9speed cassette. Works like a charm.
I putt a Wolf Tooth Road link on with a long cage ultegra derailleur. I now have a 11-42 cassette on the rear, and a compact on the front and can manage the Oman hills reasonably well.
The smile and the glazed look in Ollie's eyes as he stared out the window makes think he went into his happy dreamland when talking about building custom wheels.
Bought one of those hanger extenders for my Trek with Sram short cage and it is spot on - much cheaper than a new derailleur and other than a slight tweak to the derailleur alignment it's given me 3 years so far of hassle free use. Only went from 28T to 30T on a compact but clearly there's scope for more.
In response to the tubeless question. I have Dynaplug plugs for bicycle tyres. They seal with the tyre when inserted. They also come in 2 different size plugs. Some of the kits even come with a small knife to cut the excess off.
Same here. I carry a Dynaplug, a couple of spare plugs and a pump. That's it. If I can't solve a puncture with that I'll just call an Uber. No Ubers called yet.
As for catastrophic tubeless punctures, another great option I was told about when I had my first tire get sliced open was to bring a dollar bill with you. You fold the bill over a couple of times and use it on the inside of the tire between the tube and tire. The moisture from the sealant helps it stick in place. It works great for large slices up to a centimeter or so. I’m not sure how sturdy British paper money is, but American bills are quite tear resistant and ideal for covering large tears/cuts without letting a tube squeeze out through the hole. You guys rock, keep up all there great vids! My friends and I can’t get enough!
What I've noticed when customers have me install these extensions the derailleur will not shift very accurately on the whole range. It either works great on all the low climbing gears or the high gears, but not both.
Running tubeless. Park Tools TL 6.2 tire levers are a must in your repair kit, a proper size tube and a frame pump and CO2. Plugs are nice if your on a mountain bike however on road bikes they aren't as useful, your better off with a tube if the sealant don't seal it. Thing to do also is maybe have a small piece of old inner tube to make a boot if needed.
Wow 1 Year later and only now I find out that My Man Ollie replied to my calls :D Thanks for the video and for answering my BB Problems. I am now 1 step closer to being a home mechanic :D
#askgcntech I put my bike on my smart trainer, when riding sometimes - when I go hard and specifically out of the saddle, the headset bearing starts to make a disconcerting knocking/clicking noise which I can't, despite my best efforts, get rid of. The bike is a Canyon Ultimate CF-SL. Way to go Olly. Thanks James
regarding the first topic of the video I have two questions. First: aret there derailleur hanger extenders suitable for a Shimano Ultegra 11S SG? I heard something in the case of Wolf Tooth that it was not suitable for that model (RD-R8000-GS). And other solution I have been thinking of for the problem of pairing this rear derrailleur with a 11x40 cassette is to change the cage of the derrailleur. But the Ultegra only is manufactured with SS and SG cages. Would it be possible to install in the ultegra derrailleur a SGS cage from another Shimano model?. Please, advise my best option.
For BB30 removal I use Park Tool BBT-30.4. It's gentle on the bearings so you can reuse them. Also, that old "head set type" demonstrated here might press on the inner circlip on BB30 possibly. Bearings go out if I want to mess with the internal gear cables, for better access.
Can you tell me what a good replacement would be to replace my SRAM X-7 9 speed small cage rear derailleur , i can't find one anywhere all i find is X-5s and X-9 medium cage , I'm assuming the X-5 would be a step down so i assume the X-9 would be a step up ?
I don’t have bar tape but I have grips on my setup and I use isopropyl to clean it down every other ride. Also if you can throw a clean chain on there, as of now I’m using a towel to collect all the grease and crap that falls off the chain during my zwifting. I’m on a transition scout hooked up to a cycleops hammer2.
#AskGCNTech Does riding a bike with indoor trainer put more stress on the frame and bottom bracket? Warranty concern aside, is it better/safer to use metal bike with indoor trainer?
#askgcntech. Is it possible to purchase or custom build a rim brake wheel with a disk hub? I currently have a frame that can upgrade to disk brakes. But I also have frames that are rim only. I want interchangeable wheels to be compatible. Or would it be simpler and cheaper to have a set of dedicated disk wheels and rim wheels?
Great video once again. thx. Question - can you post a quick message about the mounting method used for the bike in the background? Want to do the same with mine, thx
On Friday I had my MTB running a SRAM Eagle 1 x 12 ( 32t front cog; 11-50 cassette ) converted to a 2 x 12 setup. The lbs mecahnic ( who generally prefers SRAM to Shimano ) did the conversion by adding Shimano components, viz. FD, front shifter and changed the SRAM 1x crankset to a Shimano 2x 36-26 ( 12s ) crankset. Works like a charm except I can't ride big-big. Would adding a goat link allow me to ride bib-big if it became necessary?
I recently changed to an 11-32 cassette and the bike shop installed an extender. I notice some of the shifting was not as smooth as before with the 11-27 and no extender. I was introduced to an alternative - the oversized jockey wheels. I bought a carbon replacement part on Ali-Express for my particular Dure-Ace derailleur and installed it in my bike. I did not need to change the length of the chain. The benefit is that the larger cassette can be accommodated but the distance between the jockey wheels and the cassette is not increased so shifting is supposedly less affected. The shifting, particularly in the mid range was improved over the extender but maybe still not as good as the original. I can’t add a picture here but will upload so you can see what I installed and how it looks on the bike. Perhaps you could check it out and let us know what you think as an alternative.
For darts or worms to fix your tubeless Tires you can clip them off about 5 to 7 mm from the tire with a pair of extra large nail clippers - are usually keep these in my pack ready for such an occasion and they were very quickly and efficiently
#AskGCNTech Hi there, does anyone know of any hacks to keep the legs of your bib shorts sticky? Essentially the gel bits on mine have stopped working, I presume through washing, and the legs keep riding up as I pedal. The rest of the bibshort is fine so I don't want to get a new pair. I would welcome any ideas! Thanks in advance
Hi Ollie love the show, I have Boardman endurance frame with a BB PF 30 bottom bracket, I run campagnolo super record chain set and would like to change the bottom bracket to something like the Token Ninga type ! I’m having difficulty in sourcing a company that produce this do you have any suggestions please.
At 0:44. Sram Force 10spd Short Cage derailleur www.modernbike.com/sram-force-10-speed-rear-road-derailleur looks like max 33T Chain Wrap Capacity, which is exactly what user "kamatiker" has on his Canyon. Chainset 50-34=16T plus cassette 28-11=17T is total 16+17=33T. Swapping to a larger cassette 36-12=24T will bring the total to 40T. Which is 7T too many for the short cage to maintain proper chain tension. Nothing a WolfTooth RoadLink will solve. Get a new derailleur with longer cage! Probably the same price as a WT RoadLink.
So I’m doing this same thing however my chainrings are 52-39 so I only have 13T upfront meaning I could probably do 11-32 with no issues? I have an 11-26 and can survive climbs since I’m pretty skinny
5:50 Paid promotion sign missing?...when Shimano battery is low, front mech shifts down to small ring and you can ride another 100km with rear derailleur working
They do push sram a lot. As I've just mentioned when Campy EPS starts to warn you to charge the battery it still has more life left than fully charged sram
Indeed! If you have the Di2 radio unit, you can also show the Di2 battery level on a Wahoo bike computer. Wahoo also shows the position of the gears on the screen, which I find very useful.
not paid promotion - note the orbea on the wall and my pinarello both have di2. i love Di2. however, an advantage of sram is that you rarely end up with both batteries flat. I have lots of experience with both.
I have enough electronic stuff with my powermeter and garmin device,also love the simple mechanical string pulled derailleur! With coated cables my Dura Ace 10 speed drive train with big ceramic wheels shifts definitely faster than DI 2...
#askgcntech a lot of new carbon bikes come with Shimano press fit bottom brackets. I prefer using SRAM, and if I did buy a new bike would want to change the groupset, including the cranks. Is it possible to fit a SRAM crankset to a pressfit frame, even though it has a gxp bb? Read a lot of stuff online but it’s all a tad confusing! Thanks, and love the show
#AskGCNTech I am currently planning to upgrade the groupset on my Specialized Allez Sport and therefore to use the bike as a daily training/club-riding bike. It has an Sora R3000 groupset, and I am planning to upgrade to an Ultegra. Do you think it is a good time for me to go for the R8000, or should I wait until the next generation releases. What do you think the major improvement of the next generation of Ultegra is going to be, and by how much is the improvement going to be?
#ASKGCNTECH: I recently removed my rear sprocket to give it a good cleaning. Upon remounting it and applying some lubricant, I went on my first ride and noticed a jingling sound from the sprocket. Upon checking the various gears, I noticed that there was a little play with the single gears. I used a chain whip and the Shimano tool to tighten up the locking ring, and the ring is quite tight. Is it okay that the individual gear rings have a little play? Or, should they be snug up against the spacers between them? Could the spacers be worn such that they need replaced? I don't recall this noise prior to the cleaning.
I think I must have short toes because I use Look Keo pedals and I can never get the cleat forward enough. I have tried a few makes of shoes and I find Diadora shoes are drilled maybe a few millimetres nearer the toe than others. It has suggested that the slots can be lengthened with a round file but that would be a bodge. Do you know of a solution?
Fast Forward make an excellent deep section wheel set which are rated for 145kg so they can handle heavier riders. These also happen to be amazing wheels with great hubs so it's win win.
#askgcntech I ride a gravel bike for everything I do from commuting when I can to actually gravel. The tire I have currently are almost mountain bike tires which are great for the loose sandy "gravel" rides here in New Mexico. I want something more efficient tire for the paved areas like the tervail ramparts. My question is should I get two wheel sets for my bike or can I switch the tires on the one wheel set? Which is the better option with tubeless setups?
#AskGCNTech Good day! Just wondering what is THE BEST for a bigger cassette a derailleur hanger extender or a long cage rear mech. Thanks and stay safe. SHOUT OUT: BIKE TO WORK NURSES IN THE PHILIPPINES.
Long cage rear mech, i've used the extender and while it works it makes bending the mech hanger on the frame very easy (extra leverage) had to reset (bend) mech hanger very often
#AskGCNTech Hi I have been wondering if i could use a Shimano 105 crankset with a 8 speed shifters, cassette, chain and derailleur. Would it be worth it or should i go for something what suits my bike. Thanks.
#askGCNtech Debating upgrading my bike to Di2 & adding clip on bars to make it a TT bike as well as a road bike. Is the process of plugging & unplugging the Di2 shifters at the end of the aero bars into the 5 port under-the-stem junction box an easy thing? I've been told I would need to reprogram the Di2 every time I plug & unplug but would like verification from you guys! Is there anything I need to know about using Di2 in this way? I want to get into TTs and adding Di2 & aerobars to my road setup is a lot cheaper than buying a full TT bike.
#askgcntech I am having issues with the second largest and 3rd from largest sprockets indexing. It’s Campagnolo record 12 speed 11-32 on a Wilier cento1air Small frame. I have checked the hanger alignment several times, my daughter did knock the bike over lightly, prior to that it was shifting ok.
Hey Ollie I think you guys should do a show on different methods of displaying your bike on the wall ... would love to know the method you use for your Orbea!
The good thing about Campagnolo EPS is that it gives you days of warning before the battery dies so once you get the warning that the battery needs to be recharged you still have more riding time than you do with fully charged sram
#AskGCNTech. Hi GCN Tech. Can you recommend a tool or method to evaluate combinaisons of cassette and chain ring sizes? I just bought a new Specialized Tarmac Comp Disk equiped with a 52/36 chain ring and an 11/30 cassette. I would like to compare alternate options to get closer to a customized combo for my taste and... ahem, capability. Should I go compact with an 11/32? What steps will I miss, etc. Much thx.
Hey Ollie!Great program as ever. Question. What about taking an extra full battery with you in your saddlebag or any other place? what could be the disadvantages? thanks!
#AskGCNTech Should i leave my chain on the easy gears (small front, big rear) after I am done riding a smart trainer? If I leave the chain on the small-small combo, it is tough to start on the next day but if I don’t, the chain, RD and FD will wear out sooner, true?
#askgcntech I have a old bike which has 9 speed campag mirage and I was looking to upgrade the wheels. which wheel manufacturers have the best compatability with the freehub body or or are the easiest to change the freehub body to the correct one
I just purchased my first indoor Wahoo trainer, which is backordered, and I have a shimano 11-32 10 speed cassette on my bike. As you know, the Wahoo trainer comes with an 11 speed cassette, but allows me to put a 10 speed cassette on it. I purchased a shimano 11-28 cassette to put on the trainer, as it was cost effective. My question is will I have any major limitations in my gear ratio going forward on Zwift for example, remember I am going to be new to all of this. Thanks in advance for you advice.
Short answer is nothing to worry about. If by chance you ever do find the loss of your easiest gear troublesome on a particular ride, you can either turn down the resistance (see zwift.com/eu/video/how-to-cycling/adjust-smart-trainer-difficulty ) or use it for motivation to push a wee bit harder :)
#AskGCNTech I am looking to upgrade my bike and training with a power meter. I currently have a full Shimano Claris groupset, would I be able to replace my crankset with either ultegra or dura ace, without having to change anything else?
Yes you can. According to bike.shimano.com , Claris is spec'd with the Tiagra BB, which is a Hollowtech-II type as well as105, Ultegra and Dura-Ace. No need to change the left STI for the FD. (Originally I even started out 2x8 on a flat bar with a 3x shifter before realising I preferred riding in the drops than on bar ends) I changed my FD with the cranks as I switched from 3x to 2x, so I can't tell if the 2x Claris FD would work. (Any official advice would most surely be not to mix and match - no surprises there to be expected - I've heard it so often, though so much more worked for me.) But for fun's sake, I'd tech trial first before swapping the FD as well. BUT the tighter tolerances of the 11speed system required a slim 11s chain in the front. Works like charm with my 8s in the back! (And I like the look of the hollow bolts in Dura-Ace chain ;) Enjoy the DIY time! Park tool videos will most surely help. P.S. My next personal upgrade will be 2x11s, but also hydraulic (instead of my mechanical) discs as well since I'll have to swap at least the right STI, I'm going for the pair and hydr. calipers. (Imo 11s is worth the trouble: Finer gear steps AND more cassette options, esp. with longer cages or hanger extender. MTB RD works with a STI lever using gadgets like the Wolftooth Tanpan.)
#AskGCNTech Ahoy from Slovakia, great show! I wanna ask if it is possible to mix different models of Di2 STI-levers - left and right one, if both are 2x11-speed compatible. For example: left lever would be ultegra st-r8050 and right one would be dura-ace st-9070 etc. I assume e-tube is must in this case? Thanks a lot!
#AskGCNTech HI! I'm looking to upgrade the stock wheels that came with my specialized allez. Looking at the vision team 30 (you used on the cheap to superbike) and team 35, they both weight about the same and cost about the same, the difference is mainly in the dimensions. The t30s have 25mm outer width and t35s have 21mm. What are the pros and cons of wider/skinnier rims? Im going to be running some 28c tubeless tires for the extra comfort, so can it even be more aerodynamic to have the wider but shallower rims as it makes smoother transition between rim and tire? Thanks.
#askGCNtech : How can you tell when the disc in a disc brake system needs to be replaced? Assuming it’s still straight and not warped. I’m installing my second set of brake pads on my road bike tomorrow. Ollie your camera man is the best!
#AskGCNTech Dear GCN Tech. I curious, is it possible to convert a road bike with a disc brakes to gravel, by using 26 inch wheels with wide tires? Is it good idea? Thanks.
Why go down to 26 inch wheels when 650b would be small enough? I converted a 700c disc brake cyclocross bike, whose rims wouldn't take a tire wider than 28 mm, into a gravel bike with 650b wheels that could take 38 mm tires.
#AskGCNtech Good evening! I recently purchased a set of Fulcrum Racing 7 DB as a second wheelset to put on my 2016 Trek Crockett. After fitting my Avid BB5 brake calipers to the new wheels, I find myself in a pickle. My old Bontrager TLR front wheel (front wheel only, rear wheel is ok) disc rotor is not fitting anymore in the caliper. Are there any shims or spacers I can use on the centerlock hub to space out the rotor? Should I try to use a centerlock to 6 bolt adapter to use 6 bolt disc spacers? Any other tips other than refitting the caliper every time I want to swap wheels? Thank you!
Probably all you need to do is loosen the bolts holding the calipers to the fork and chainstays. Then, pull the brake levers and the calipers will likely center. Tighten while holding the brake lever. I have to do this when swapping wheels.
#askgcntech my hanger is straight, RD is fine and set up correctly, Cassette and chain is fine, cables still smooth, the brifter feels smooth, but most of the time i need a few mm extra pull on the lever after the click when go up the cassette so it went in perfectly.. i try play around with tension but the symptoms that i got are just like a bent hanger (either easy up late down or vice versa), the shop guy checked with paktool DAG and find no problem. i run sora 3400 brifter with acera shadow rd, this also happened with sora rd and feel little bit worse than acera shadow. any idea?
I'd love to see an episode dedicated to heavy riders. I'm 320 lbs and routinely do century rides on a cafe bike ... because I know it won't break under strain. I fear going with lighter or more efficient bikes because I don't know what will support me.
I would love to see an episode focused on the bigger guys and gals as well. I used to weigh in at 360lbs, got a touring bike with a some very strong wheels. Am now 260lbs thanks to a few good decisions in life and the bike as well. Am interested in moving towards more endurance road bikes as I get a bit lighter, which was the reason for my question. Know that most frames support my weight as is, but the weak point will probably be the wheel hence the question. I of course ride tubeless to avoid pinch flats and fit a 29"x2.2" tire on my touring rig but longing for a bit more speed. I would very much appreciate an episode focused on larger cyclists. Clothing choices, bike fit, proper equipment to use for a stronger bike etc...
#askgcntech...do road shoes come with cleats...which ones to buy...btwin 500 or shimano rc7(for double the price) and..tyres on Triban RC 520... Are they tubeless... because the wheels are and in their conversation kit..they don't mention tyre...so??Also, I have a leak where the valve is glued to the inner tube...how can I fix it..
1)go for the Shimano shoes (speaking of experience) 2) the tires arent tubeless. But the rims are. Youll just need tires, valves and sealant 3) just put a regular patch on the leak and it should fix it. If it's completely against the valve, change the tube
#askgcntech Hi GCN! I am planning to upgrade my rear derailleur from a Shimano 105 R5800 Short Cage to a Shimano Ultegra RX800 Long Cage. My cassette is a 11T to 18T. May I ask if I would need to change my chain length of it will just be fine? Cheers and stay safe :-D
#AskGCNTech my secondhand 2003 Trek 5200 doesn’t have a derailleur hanger. It mounts directly to the metal bracket that the wheel/frame mounts to. Should a hanger be added as a sacrificial bracket to avoid the frame or derailleur being damaged?
#askgcntech The outside plate of my new ultegra front derailleur rubs on side of chain when in Biggie smalls. Even with cable removed and limit screw backed out. What the heck?
#askgcn Hi guys my freewheel on my bike has started to have a gritty sound and feel to it and sometimes stops functioning I was just wondering what the best thing is to do. The actual wheel bearings are fine I think it’s the freewheel. The wheel is a specialized axis. Great show thanks a lot.
#AskGCNTech Why might someone still choose 23c tires, unless their frame limits them to this choice? Full disclosure, I have a few NOS 23s, and don’t know what to do with them. Trainer tires?
A few days ago, I rode my rebuilt steel road bike for the first time in 20 years (25mm tyres, wider tyres won't fit). A-M-A-Z-I-N-G. I probably will build me a bike for travelling around and I know now: it will be a steel bike.
@gcntech How do i convert a rear thru-axle hub to 9mm quick release? The issue I'm running into is the width. They sell those adapters you just run through it but the issue is that the width with the george-endcappy's of the hubs are too wide for a 9mm quick-release frame. What the heck does a guy do? Where do i get them sweet sweet parts to make this happen? (without just grinding it down.. (done that once :-/ )) FYI, I have threaded axles on a set of "OVAL" wheels. www.ovalconcepts.com/road/wheels/928-disc-wheelset
Ollie the amateur cyclist that does 20 min at 31 mph? That’s what 53x15 at 113rpm is. You should really give yourself some more credit, you may not be a ex pro but you’re pretty fast.
#AskGCNTech - Love the show (you nailed the broadcast from home!!) I got some rollers for the covid lockdown but after ‘mastering’ them they shredded my nearly new gatorskin 25c tyres after just an hour - is this inevitable, do you have any hacks or do I need to abandon them and get a turbo trainer?
I'd recommend putting on some older and worn tires if riding on rollers. You can also buy rollerspecific tires (kinda cheap, +-20 euros I think), that are a lot more durable for rollers (don't ride them on the road though) and will save you quite a bit in the long run. it is inevitable because rollers wear out your tires a lot more because of higher friction, heat and a very small contactpoint. :)
I put a dish towel over my bar tape and change the towel with every ride. It has kept my white bar tape pristine over 3K miles on the trainer. No need to wear gloves, either.
#askGCNtech Hi guys, loving the show, keep up the good work and all of that. I have an early 90' CILO SWISS and I'm doing a resto/mod on it, but I'm on a budget. It is a mish mash of parts but mostly Shimano 105 from the 5700 series.I was thinking of using some Microshift R10 shifters. Do you have any info on the build quality? I've been finding some oposit comments on the net. Thanks in advance! Branko from Zagreb, Croatia :)

The bike is a Canyon Ultimate CF-SL. Way to go Olly. Thanks James
Take out the crank and grease the bearing hub and crank arm. I had the same issue and this fixed it right up
As for on the ride flat fix. Slime has a tire patch kit that works fine. I’ve used it on my tube but it should work for the inside of a tubeless.
regarding the first topic of the video I have two questions. First: aret there derailleur hanger extenders suitable for a Shimano Ultegra 11S SG? I heard something in the case of Wolf Tooth that it was not suitable for that model (RD-R8000-GS). And other solution I have been thinking of for the problem of pairing this rear derrailleur with a 11x40 cassette is to change the cage of the derrailleur. But the Ultegra only is manufactured with SS and SG cages. Would it be possible to install in the ultegra derrailleur a SGS cage from another Shimano model?. Please, advise my best option.
For BB30 removal I use Park Tool BBT-30.4. It's gentle on the bearings so you can reuse them. Also, that old "head set type" demonstrated here might press on the inner circlip on BB30 possibly. Bearings go out if I want to mess with the internal gear cables, for better access.

I don’t have bar tape but I have grips on my setup and I use isopropyl to clean it down every other ride.
Also if you can throw a clean chain on there, as of now I’m using a towel to collect all the grease and crap that falls off the chain during my zwifting. I’m on a transition scout hooked up to a cycleops hammer2.
#AskGCNTech
Does riding a bike with indoor trainer put more stress on the frame and bottom bracket? Warranty concern aside, is it better/safer to use metal bike with indoor trainer?
David Lam Good question!
With the rear derailleur extender, do you end up with the same chain length or was the tension OK? anybody experience on this? Thanks!!
#askgcntech. Is it possible to purchase or custom build a rim brake wheel with a disk hub? I currently have a frame that can upgrade to disk brakes. But I also have frames that are rim only. I want interchangeable wheels to be compatible. Or would it be simpler and cheaper to have a set of dedicated disk wheels and rim wheels?

On Friday I had my MTB running a SRAM Eagle 1 x 12 ( 32t front cog; 11-50 cassette ) converted to a 2 x 12 setup. The lbs mecahnic ( who generally prefers SRAM to Shimano ) did the conversion by adding Shimano components, viz. FD, front shifter and changed the SRAM 1x crankset to a Shimano 2x 36-26 ( 12s ) crankset. Works like a charm except I can't ride big-big. Would adding a goat link allow me to ride bib-big if it became necessary?
I recently changed to an 11-32 cassette and the bike shop installed an extender. I notice some of the shifting was not as smooth as before with the 11-27 and no extender. I was introduced to an alternative - the oversized jockey wheels. I bought a carbon replacement part on Ali-Express for my particular Dure-Ace derailleur and installed it in my bike. I did not need to change the length of the chain. The benefit is that the larger cassette can be accommodated but the distance between the jockey wheels and the cassette is not increased so shifting is supposedly less affected. The shifting, particularly in the mid range was improved over the extender but maybe still not as good as the original. I can’t add a picture here but will upload so you can see what I installed and how it looks on the bike. Perhaps you could check it out and let us know what you think as an alternative.
Hey Ollie, how do you have your bike mounted on the wall behind you?
Where can you get custom paint jobs and how much would they cost?
For darts or worms to fix your tubeless Tires you can clip them off about 5 to 7 mm from the tire with a pair of extra large nail clippers - are usually keep these in my pack ready for such an occasion and they were very quickly and efficiently
Great quality for a self-shot vid! You even managed to place your product sponsor in the shot!
#AskGCNTech Hi there, does anyone know of any hacks to keep the legs of your bib shorts sticky? Essentially the gel bits on mine have stopped working, I presume through washing, and the legs keep riding up as I pedal. The rest of the bibshort is fine so I don't want to get a new pair. I would welcome any ideas! Thanks in advance
SO impressed with this home working setup! Nice one Ollie!
Hi Ollie love the show, I have Boardman endurance frame with a BB PF 30 bottom bracket, I run campagnolo super record chain set and would like to change the bottom bracket to something like the Token Ninga type ! I’m having difficulty in sourcing a company that produce this do you have any suggestions please.
At 0:44. Sram Force 10spd Short Cage derailleur www.modernbike.com/sram-force-10-speed-rear-road-derailleur looks like max 33T Chain Wrap Capacity, which is exactly what user "kamatiker" has on his Canyon. Chainset 50-34=16T plus cassette 28-11=17T is total 16+17=33T. Swapping to a larger cassette 36-12=24T will bring the total to 40T. Which is 7T too many for the short cage to maintain proper chain tension. Nothing a WolfTooth RoadLink will solve. Get a new derailleur with longer cage! Probably the same price as a WT RoadLink.
So I’m doing this same thing however my chainrings are 52-39 so I only have 13T upfront meaning I could probably do 11-32 with no issues? I have an 11-26 and can survive climbs since I’m pretty skinny
5:50 Paid promotion sign missing?...when Shimano battery is low, front mech shifts down to small ring and you can ride another 100km with rear derailleur working
They do push sram a lot. As I've just mentioned when Campy EPS starts to warn you to charge the battery it still has more life left than fully charged sram
Indeed! If you have the Di2 radio unit, you can also show the Di2 battery level on a Wahoo bike computer. Wahoo also shows the position of the gears on the screen, which I find very useful.
not paid promotion - note the orbea on the wall and my pinarello both have di2. i love Di2. however, an advantage of sram is that you rarely end up with both batteries flat. I have lots of experience with both.
I have enough electronic stuff with my powermeter and garmin device,also love the simple mechanical string pulled derailleur!
With coated cables my Dura Ace 10 speed drive train with big ceramic wheels shifts definitely faster than DI 2...
#askgcntech a lot of new carbon bikes come with Shimano press fit bottom brackets. I prefer using SRAM, and if I did buy a new bike would want to change the groupset, including the cranks. Is it possible to fit a SRAM crankset to a pressfit frame, even though it has a gxp bb? Read a lot of stuff online but it’s all a tad confusing! Thanks, and love the show
Is rd extender gonna make the shifting performance smooth
#AskGCNTech I am currently planning to upgrade the groupset on my Specialized Allez Sport and therefore to use the bike as a daily training/club-riding bike. It has an Sora R3000 groupset, and I am planning to upgrade to an Ultegra. Do you think it is a good time for me to go for the R8000, or should I wait until the next generation releases. What do you think the major improvement of the next generation of Ultegra is going to be, and by how much is the improvement going to be?
#ASKGCNTECH: I recently removed my rear sprocket to give it a good cleaning. Upon remounting it and applying some lubricant, I went on my first ride and noticed a jingling sound from the sprocket. Upon checking the various gears, I noticed that there was a little play with the single gears. I used a chain whip and the Shimano tool to tighten up the locking ring, and the ring is quite tight. Is it okay that the individual gear rings have a little play? Or, should they be snug up against the spacers between them? Could the spacers be worn such that they need replaced? I don't recall this noise prior to the cleaning.
I think I must have short toes because I use Look Keo pedals and I can never get the cleat forward enough. I have tried a few makes of shoes and I find Diadora shoes are drilled maybe a few millimetres nearer the toe than others. It has suggested that the slots can be lengthened with a round file but that would be a bodge. Do you know of a solution?
Fast Forward make an excellent deep section wheel set which are rated for 145kg so they can handle heavier riders. These also happen to be amazing wheels with great hubs so it's win win.
What kind of drawbacks of using a extender to increase the capacity of a rear derailuer
#askgcntech I ride a gravel bike for everything I do from commuting when I can to actually gravel. The tire I have currently are almost mountain bike tires which are great for the loose sandy "gravel" rides here in New Mexico. I want something more efficient tire for the paved areas like the tervail ramparts. My question is should I get two wheel sets for my bike or can I switch the tires on the one wheel set? Which is the better option with tubeless setups?
#AskGCNTech
Good day! Just wondering what is THE BEST for a bigger cassette a derailleur hanger extender or a long cage rear mech. Thanks and stay safe.
SHOUT OUT: BIKE TO WORK NURSES IN THE PHILIPPINES.
Long cage rear mech, i've used the extender and while it works it makes bending the mech hanger on the frame very easy (extra leverage) had to reset (bend) mech hanger very often
#AskGCNTech
Hi
I have been wondering if i could use a Shimano 105 crankset with a 8 speed shifters, cassette, chain and derailleur.
Would it be worth it or should i go for something what suits my bike.
Thanks.
#askGCNtech Debating upgrading my bike to Di2 & adding clip on bars to make it a TT bike as well as a road bike. Is the process of plugging & unplugging the Di2 shifters at the end of the aero bars into the 5 port under-the-stem junction box an easy thing? I've been told I would need to reprogram the Di2 every time I plug & unplug but would like verification from you guys! Is there anything I need to know about using Di2 in this way? I want to get into TTs and adding Di2 & aerobars to my road setup is a lot cheaper than buying a full TT bike.
Ollie, I would like to upgrade my tyres what do you think is then best option?
#askgcntech I am having issues with the second largest and 3rd from largest sprockets indexing. It’s Campagnolo record 12 speed 11-32 on a Wilier cento1air Small frame. I have checked the hanger alignment several times, my daughter did knock the bike over lightly, prior to that it was shifting ok.
With the Deralleur extender, should you add more links to your chain or none needed?
Hey Ollie I think you guys should do a show on different methods of displaying your bike on the wall ... would love to know the method you use for your Orbea!
The good thing about Campagnolo EPS is that it gives you days of warning before the battery dies so once you get the warning that the battery needs to be recharged you still have more riding time than you do with fully charged sram
#AskGCNTech. Hi GCN Tech. Can you recommend a tool or method to evaluate combinaisons of cassette
and chain ring sizes? I just bought a new Specialized Tarmac Comp Disk equiped with a 52/36 chain ring and an 11/30 cassette. I would like to compare alternate options to get closer to a customized combo for my taste and... ahem, capability. Should I go compact with an 11/32? What steps will I miss, etc. Much thx.
Hey Ollie!Great program as ever. Question. What about taking an extra full battery with you in your saddlebag or any other place? what could be the disadvantages? thanks!
#AskGCNTech Should i leave my chain on the easy gears (small front, big rear) after I am done riding a smart trainer? If I leave the chain on the small-small combo, it is tough to start on the next day but if I don’t, the chain, RD and FD will wear out sooner, true?
#askgcntech I have a old bike which has 9 speed campag mirage and I was looking to upgrade the wheels. which wheel manufacturers have the best compatability with the freehub body or or are the easiest to change the freehub body to the correct one
I just purchased my first indoor Wahoo trainer, which is backordered, and I have a shimano 11-32 10 speed cassette on my bike. As you know, the Wahoo trainer comes with an 11 speed cassette, but allows me to put a 10 speed cassette on it. I purchased a shimano 11-28 cassette to put on the trainer, as it was cost effective. My question is will I have any major limitations in my gear ratio going forward on Zwift for example, remember I am going to be new to all of this. Thanks in advance for you advice.
Short answer is nothing to worry about. If by chance you ever do find the loss of your easiest gear troublesome on a particular ride, you can either turn down the resistance (see zwift.com/eu/video/how-to-cycling/adjust-smart-trainer-difficulty ) or use it for motivation to push a wee bit harder :)
#AskGCNTech I am looking to upgrade my bike and training with a power meter. I currently have a full Shimano Claris groupset, would I be able to replace my crankset with either ultegra or dura ace, without having to change anything else?
Yes you can. According to bike.shimano.com , Claris is spec'd with the Tiagra BB, which is a Hollowtech-II type as well as105, Ultegra and Dura-Ace. No need to change the left STI for the FD. (Originally I even started out 2x8 on a flat bar with a 3x shifter before realising I preferred riding in the drops than on bar ends) I changed my FD with the cranks as I switched from 3x to 2x, so I can't tell if the 2x Claris FD would work. (Any official advice would most surely be not to mix and match - no surprises there to be expected - I've heard it so often, though so much more worked for me.) But for fun's sake, I'd tech trial first before swapping the FD as well. BUT the tighter tolerances of the 11speed system required a slim 11s chain in the front. Works like charm with my 8s in the back! (And I like the look of the hollow bolts in Dura-Ace chain ;)
Enjoy the DIY time! Park tool videos will most surely help.
P.S.
My next personal upgrade will be 2x11s, but also hydraulic (instead of my mechanical) discs as well since I'll have to swap at least the right STI, I'm going for the pair and hydr. calipers. (Imo 11s is worth the trouble: Finer gear steps AND more cassette options, esp. with longer cages or hanger extender. MTB RD works with a STI lever using gadgets like the Wolftooth Tanpan.)
#AskGCNTech
Ahoy from Slovakia, great show! I wanna ask if it is possible to mix different models of Di2 STI-levers - left and right one, if both are 2x11-speed compatible. For example: left lever would be ultegra st-r8050 and right one would be dura-ace st-9070 etc. I assume e-tube is must in this case? Thanks a lot!
For the chain ring part, not all bikes that have shimano parts have the shimano cranks on them
#AskGCNTech HI! I'm looking to upgrade the stock wheels that came with my specialized allez. Looking at the vision team 30 (you used on the cheap to superbike) and team 35, they both weight about the same and cost about the same, the difference is mainly in the dimensions. The t30s have 25mm outer width and t35s have 21mm. What are the pros and cons of wider/skinnier rims? Im going to be running some 28c tubeless tires for the extra comfort, so can it even be more aerodynamic to have the wider but shallower rims as it makes smoother transition between rim and tire? Thanks.
#askGCNtech : How can you tell when the disc in a disc brake system needs to be replaced? Assuming it’s still straight and not warped. I’m installing my second set of brake pads on my road bike tomorrow. Ollie your camera man is the best!
Antimicrobial bar tape works great!
#AskGCNTech Dear GCN Tech. I curious, is it possible to convert a road bike with a disc brakes to gravel, by using 26 inch wheels with wide tires? Is it good idea? Thanks.
Why go down to 26 inch wheels when 650b would be small enough? I converted a 700c disc brake cyclocross bike, whose rims wouldn't take a tire wider than 28 mm, into a gravel bike with 650b wheels that could take 38 mm tires.
#AskGCNtech
Good evening!
I recently purchased a set of Fulcrum Racing 7 DB as a second wheelset to put on my 2016 Trek Crockett. After fitting my Avid BB5 brake calipers to the new wheels, I find myself in a pickle. My old Bontrager TLR front wheel (front wheel only, rear wheel is ok) disc rotor is not fitting anymore in the caliper. Are there any shims or spacers I can use on the centerlock hub to space out the rotor? Should I try to use a centerlock to 6 bolt adapter to use 6 bolt disc spacers? Any other tips other than refitting the caliper every time I want to swap wheels?
Thank you!
Probably all you need to do is loosen the bolts holding the calipers to the fork and chainstays. Then, pull the brake levers and the calipers will likely center. Tighten while holding the brake lever. I have to do this when swapping wheels.
@@bleckb Thank you! Yes I know that technique, but i want a more permanent and less inconvenient way to swap my wheels easily. :)
#askgcntech
my hanger is straight,
RD is fine and set up correctly, Cassette and chain is fine,
cables still smooth,
the brifter feels smooth,
but most of the time i need a few mm extra pull on the lever after the click when go up the cassette so it went in perfectly..
i try play around with tension but the symptoms that i got are just like a bent hanger (either easy up late down or vice versa),
the shop guy checked with paktool DAG and find no problem.
i run sora 3400 brifter with acera shadow rd, this also happened with sora rd and feel little bit worse than acera shadow.
any idea?
Please include on your description time for each theme. More easy for users
how about 650b wheels? fixes the tire clearance problems, maybe....
What is the best way to clean my direct drive indoor trainer cassette without damaging the trainer or getting the cassette off #ASKGCNTech
I use baby wipes to clean my bartape after every other ride. Easy to use and effective.
I'd love to see an episode dedicated to heavy riders. I'm 320 lbs and routinely do century rides on a cafe bike ... because I know it won't break under strain. I fear going with lighter or more efficient bikes because I don't know what will support me.
staff0flag Good deal my friend. Cycling is the best for exercise, easy on the knees and less strees
I would love to see an episode focused on the bigger guys and gals as well. I used to weigh in at 360lbs, got a touring bike with a some very strong wheels. Am now 260lbs thanks to a few good decisions in life and the bike as well. Am interested in moving towards more endurance road bikes as I get a bit lighter, which was the reason for my question. Know that most frames support my weight as is, but the weak point will probably be the wheel hence the question. I of course ride tubeless to avoid pinch flats and fit a 29"x2.2" tire on my touring rig but longing for a bit more speed.
I would very much appreciate an episode focused on larger cyclists. Clothing choices, bike fit, proper equipment to use for a stronger bike etc...
#askgcntech...do road shoes come with cleats...which ones to buy...btwin 500 or shimano rc7(for double the price) and..tyres on Triban RC 520... Are they tubeless... because the wheels are and in their conversation kit..they don't mention tyre...so??Also, I have a leak where the valve is glued to the inner tube...how can I fix it..
1)go for the Shimano shoes (speaking of experience)
2) the tires arent tubeless. But the rims are. Youll just need tires, valves and sealant
3) just put a regular patch on the leak and it should fix it. If it's completely against the valve, change the tube
Pedals come with cleats, not shoes but you can buy cleats separately
@ A question for Oliver. Which bike rack do you use in your room? Looks real tidy and I'm looking for something like that.
Henrik Ørum answered in this weeks tech show!
#askgcntech Hi GCN! I am planning to upgrade my rear derailleur from a Shimano 105 R5800 Short Cage to a Shimano Ultegra RX800 Long Cage. My cassette is a 11T to 18T. May I ask if I would need to change my chain length of it will just be fine? Cheers and stay safe :-D
#AskGCNTech my secondhand 2003 Trek 5200 doesn’t have a derailleur hanger. It mounts directly to the metal bracket that the wheel/frame mounts to. Should a hanger be added as a sacrificial bracket to avoid the frame or derailleur being damaged?
No.
Depends. Are you planning to crash a lot? ;-)
Chris Ko My thighs pack a lot of thunder, that’s my primary concern.
If the bar tape is soaked after cleaning use the fan to dry it .
Can the extender also be used for campagnolo rear mech?
yes definitely. I believe there is a specific campagnolo one on the Wolftooth website. They are really good at answering your questions.
#askgcntech The outside plate of my new ultegra front derailleur rubs on side of chain when in Biggie smalls. Even with cable removed and limit screw backed out. What the heck?
What are unless tyres???
#askgcntech can you use a wolf tooth without a hanger? I am doing up a vintage Raleigh Equipe probably from the 80’s the 80’s!
For a tyre boot use an old
inner tube
for smell - baking soda. might help
#askgcn Hi guys my freewheel on my bike has started to have a gritty sound and feel to it and sometimes stops functioning I was just wondering what the best thing is to do. The actual wheel bearings are fine I think it’s the freewheel. The wheel is a specialized axis. Great show thanks a lot.
#AskGCNTech Why might someone still choose 23c tires, unless their frame limits them to this choice? Full disclosure, I have a few NOS 23s, and don’t know what to do with them. Trainer tires?
Very lightweight people?
T30 on the chainring bolts. I had to buy a whole set to get one for my torque wrench grrr....
T27??? Does that even exist?
Guido Spanoghe yes there is one in my set haha
Vibration damping? 32mm Tyres and steel frame. :) No problem.
A few days ago, I rode my rebuilt steel road bike for the first time in 20 years (25mm tyres, wider tyres won't fit). A-M-A-Z-I-N-G. I probably will build me a bike for travelling around and I know now: it will be a steel bike.
@gcntech How do i convert a rear thru-axle hub to 9mm quick release? The issue I'm running into is the width. They sell those adapters you just run through it but the issue is that the width with the george-endcappy's of the hubs are too wide for a 9mm quick-release frame. What the heck does a guy do? Where do i get them sweet sweet parts to make this happen? (without just grinding it down.. (done that once :-/ )) FYI, I have threaded axles on a set of "OVAL" wheels. www.ovalconcepts.com/road/wheels/928-disc-wheelset
Ollie the amateur cyclist that does 20 min at 31 mph? That’s what 53x15 at 113rpm is. You should really give yourself some more credit, you may not be a ex pro but you’re pretty fast.
Here's a question for gcn tech. Where's Jon?
#AskGCNTECH whats the difference between B-link and direct mount derailleur hangers?
Great video don't sell yourself short
#AskGCNTech - Love the show (you nailed the broadcast from home!!)
I got some rollers for the covid lockdown but after ‘mastering’ them they shredded my nearly new gatorskin 25c tyres after just an hour - is this inevitable, do you have any hacks or do I need to abandon them and get a turbo trainer?
I'd recommend putting on some older and worn tires if riding on rollers. You can also buy rollerspecific tires (kinda cheap, +-20 euros I think), that are a lot more durable for rollers (don't ride them on the road though) and will save you quite a bit in the long run. it is inevitable because rollers wear out your tires a lot more because of higher friction, heat and a very small contactpoint. :)
Arne - thanks so much!
Use it anytime you have a cassette bigger than 34t
Ollie = best Jon replacement option. Search over?
I put a dish towel over my bar tape and change the towel with every ride. It has kept my white bar tape pristine over 3K miles on the trainer. No need to wear gloves, either.
10:38 oh, Ollie randomly pulls a pair of top-end cranks... Bet everyone would wish to have that stuff lying around just like socks
Can i use 11 speed crankset on 10 speed drivetrain? #AskGCNTECH
#askgcntech What happened to Jon?
#askGCNtech
Hi guys, loving the show, keep up the good work and all of that. I have an early 90' CILO SWISS and I'm doing a resto/mod on it, but I'm on a budget. It is a mish mash of parts but mostly Shimano 105 from the 5700 series.I was thinking of using some Microshift R10 shifters. Do you have any info on the build quality? I've been finding some oposit comments on the net. Thanks in advance! Branko from Zagreb, Croatia :)
