Pretty impressed how PT mounts a camera and an Autocue onto the Giant, maintaining pace, while reading from of it flawlessly....
The reason for the Full-Suspension Hardtail Setup is that riders must use the same bike for both short track and olympic distance, which are very different courses.
That's what I'd heard too without trying trying to sound like an echo chamber for PT I can still a market albeit a small one maybe companies like Push or betd could probably make some money from the idea of lets call em "damper blankers" - actually, i might copyright that cha ching 💰 💰 💰
Seems having a rigid structure would put a ton of stress on the bolts and attachment points. This is where having an elastomer bushing would help
@@Velodictorian they're the same bolts that would hold the shock in place and the attachment points are designed to already take these loads, so as long as it's all torqued up properly it should be fine.
@@jonnythelegs2597it's not the same loading at all, since you've removed the spring/damper. A rigid link would pass vastly more peak load as well as overall loading would be increased
Wrote this in a few other replies - when the Chinese factories do the ISO/fatigue testing they use a rigid steel link in place of the shock. They never use a shock. So in theory the frame is validated for these higher peak loads.
Family business is CNC machining. Material costs have gone wild since COVID, and have since begun to return to normal.
We do OE production for a major japanese motorcycle manufacturer, and the vast majority of the expense of any of the items we produce is time, not really materials, so I have a hard time buying that major fluctuations in retail prices are due to material cost.
I could be, and probably am wrong though. Every part and application is different.
Great comment. In automotive i would 100% agree with you. Its time. But this is Campagnolo making niche bicycle parts. Vastly different volumes!
@@PeakTorque I can’t say too much, but we work with their factory race teams and then produce the final parts to production that are sold as aftermarket upgrades. Think a couple thousands units a year. I don’t pretend to know how many groupsets Campy sells at SR-EPS level, but it’s probably not massively off that?
We also produce chainrings for BMX bikes, albeit much smaller, we only use 2 different size of bar stock to cut blanks for a range of sizes.
Anyhow, who knows.
@@PeakTorque imo, all these bike companies are like, “People are paying $8000 for frames so let’s see what we can get away with charging” if nothing stays in stock, frankly, they can get away with it until people just decide that that’s crazy
About campy gear ratios … it seems that old 12 speed chianrings and cassettes can still be used with the new wireless group, and pro teams are actually using the old gear
i truly appreciate the hands up to passing cyclists, "this is the way"!
Its bizarre to hear the cycling industry countering their own arguments:
Don’t cross chain! - Go 1x
Bigger pulley wheels, less angle, less drag. - Go 50t-10t
Big improvement on the sound, cheers!
Good old high pass filter
@@PeakTorque As an audio engineer, I appreciate it big time
I concur.
@@beheermeneer Would you be an engineer without stating you are engineer?? 😝
@@jeremys2159 well, I can't be audio, can I
Since UAE ditched Campagnolo they haven't had a groupset sponsor to my knowledge, so they are just buying retail Shimano. I'd guess this is to enable precisely these kinds of non standard components. They've also used non-shimano carbon chainrings at some point. What's even stranger than these adapters, is that they use the Shimano power meter even though they don't have to.
Great stuff, looking forward to the tyre show
Campagnolo tested the losses between a 10/11 sprocket on a jig and decided the losses were negligible. Something like 0.1W I think they said. At least that’s what I remember anyway!
Thanks for the vid! I like the talking-while-riding format :)
I believe Roglic was using a 40T up front (40-44).
Where did you read 40t? I also read it was 46t on a Eurosport article but that can't be right.
I also appreciate he is filming and having both hands on the bars, rather than taking a hand off to film. It reminds me of those drivers we criticise for driving and holding their phones...
They decided not to use a mtb chainkeeper on that 1x, very risky and foolish to save 10g
Replacing the rear shock with a static piece is much less convenient than having a front+back lockout system, unless you are 100% certain there will be no rough patches. Sounds like a race-specific optimisation, since it removes a few grams on specific routes without the hassle of switching the bike.
There are suspension lockouts which cover the rear and the front using one lever. Scott and Cannondale offer such setups from the factory, and after-market splitters exist. Highly recommended if your MTB riding involves lots of pedalling sections, not just one climb to do one descent. The partial lockout position makes a full suspension bike feel like a hardtail (hello, gravel trail), and the full lockout is nice on any tarmac connectors.
Audio was on point! That bike makes some nice whoosh noises.
Deep wheels and the quite high pressures probably! Not ideal for everyday
@@PeakTorque it's creates a wonderful ride ambience, totally addictive.
@@manfrommontreal especially when there's little wind and its warm. A rare floaty dat!
Yaaaay! I feel like all the “bring back the truth show” comments I put under the old truth shows finally paid off hahaha!! Looking forward to more!
Btw, your right knee seems to be traveling side to side on top of the pedal stroke while your left looks stable. Could be interesting to see you analyze and tackle that on a video with your usual nonsense approach to things. ✌️
My bulky totem
Use regular Campy 12 speed mechanical, and then add the smaller cassette from the new groupset for flat races.
I think a 52/36 with 10-25 would be great for riding and racing in Florida. And then I can still throw on an 11-34 if I need to climb.
They are still supplying 12spd mechanical in rim brake. From what I’ve heard
would be really neat to see the semi flexible wishbone take place of a rear shock on bikes like that but i imagine it would be difficult to tune for rider weight
wow, incoming collaboration with bicycle RR sounds really cool
I take scrap to the scrapyard on my ebike, prices are down on all metals.
You can always find an example to prove your point but mostly they're selective. The 1w loss of smaller chainrings. Take into account also the 43g of added weight of the 11-34 DA cassette. I don't know what is faster or not but the four gel calculation picking a single variable is cartoonish.
The cervelo linklock is probably only there to turn the bike into a hardtail for the xcc race, as they are not allowed to use a different frame for the xcc compared to the xco.
Campagnolo just added three more batteries who's charging levels want to get monitored,
so YOU with your camera and mike would ahead of a ride now have to check:
- camera
- mike
- phone
- head-unit
- backlight
- frontlight (me, as I use to return in darkness)
- 3x Campa Super Record
= 9 items.
I converted most bikes to hub dynos with internal cables to front and backlight, have no head unit or camera
so have to care "only" for
- phone and
- emergency backlight.
I fail to have both of them charged properly always more often than not...
There will soon be a time, when the most hyped innovation in bike parts will be a groupset, with friction optimized mechanical drive, that you can feed through integrated stem/headsets, as is already possible with some patience today with a standard mechanical groupset and Nokon- hulls.
Argument:
"Just enjoy riding your bike"...
Campa will find a way to make it even more expensive...
"Just enjoy riding your bike"... Already do, the only battery on it is inside the Cateye thing that tells me how slow I'm going and how far I rode. No more batteries until they help make the bike go when my old legs are no longer up to big climbs....which is coming soon I'm afraid.
Shimano 105 and ultegra have limited chainring sizes to 52/36. The front derailleur doesn't support the 54/40, so while not as bad as sram or campag they are still limiting it below dura ace.
You can't officially use more than a 52, I use a rotor 53t and some friends of mine use a 54t and 55t it works just fine
@simonderoo9189 that's good to hear. Have you got new 12 speed chainrings? I've got a quarq 5 bolt power metre with 11 speed rotor 54/39 rings that I'd like to carry on using.
@@alexanderhardy971 yeah I have the new 12 speed rotor chainrings, not as good as the ultegra ones but they do the job. They shift fine, it's just not as lightning fast as the ultegra chainrings
Ultegra supports 54T. Conflicting info by Shimano. I’m using 54/40 with Ultegra 8150 FD.
you can tell the steel costs went down a lot recently because 12 speed chains went from 60 euros a pop to 20. Still can't find them at the local shop though...
No way this is solely because of material costs.
AG2R Citroën Team (BMC this year but Decathlon bike for 2024) is the only team with Campagnolo and looks like next year they will not use them. Is that a sign?
Yep, a sign that Vincenza no longer thinks pro team endorsements are worth the cost. Geez, teams will use "F___kin' SRAM" (to quote Mollema) if the checks are big enough so what does a pro team endorsement prove other than who writes the fattest checks? Meanwhile, if they have to buy it, pro teams will use Shimano: stuff works OK, is universally available and understood...it's now the standard that Campagnolo used to be. Times change.
Sound very impressive, particularly with the speed, what mic are you using- Dji? Much noise adjustment required n post-production?
would still love to see some detail on the mount youve made for the 360. cheers
Cervelo is owned by the same company that owns Santa Bikes, so the new Cervelo looks a lot like the Santa Cruz Blur 4....some say it's the same suspension geo, just a little different look
The Nylon-infused carbon rims seem pretty interesting. But I wonder if the "recyclability" aspect will make any difference at all in reality. They would need a special facility to recycle exactly these rims - right now I don't believe any company would invest in such a facility, it just wouldn't profitable. So they may very well end up in the same landfill as every other carbon rim.
I agree
I've always liked thermoplastic over thermoset. I wonder if TP rims have a more muted ride quality due to the slightly softer material?
That's exactly what all of those using the mountain bike equivalent of these wheels have said. The vibration seems to die out quicker.
They do claim that in their blurb i think. Slightly improved damping
After using the nylon rims on bmx as a kid they might be a more muted ride as from memory the Araya wheels weren't as harsh. That could be down to using the wider tyres of course
Do you think there's any structural risk when removing the suspension from a flex-stay linkage? I assume that failure on those is only a risk when pushed beyond their intended travel rather than facing undamped impacts. But, I figured that the reason we'll never see lockout shock replacements is because of the potential warranty nightmares companies would deal with when 200lb customers launch their XC bikes off huge features with a lockout bar installed.
Great point. I guess they won't offer it to the market. However, when the Chinese factories validate these frames on the fatigue rigs, they always use a fully rigid steel link (never a shock). So in theory they are validated to this kind of load.
If the mounting points are well engineered the should be no less able with a rigid interface strut. Some energy is absorbed with the suspension and transmitted in heat which would reduce transfer of energy through the frame but only marginal. Fatigue from torsion might be a concern if the strut is Inferior to purpose.im sure Cervelo have bench cycled the frame and strut with a decent margin.
Oh god I’m going to have to throw away my tyres to get ones 1.4w faster again aren’t I?
Can you comment on a Thermo plastic being used in conjunction with lignin based carbon fibres as a more recyclable/benign sustainable material for bikes as opposed to polyacrylonitrile based CF (PAN-CF).
I think the CK rims arent as bad, in terms if percormance, CK hubs are generally heavy. LB and FS sell wheels with CK hubs and those r heavier then dtswiss, carbon-ti, bitex or any inhouse hubs.
They claim a rim (44-30.5/25) weight of 435g
Almost equivalent LB rims:
AR 45 (45-30/21): standard: 460g, flyweight: 390g
WR 38 (38-32.4/25) : standard : 440g, flyweight: 395g
Flyweight rims has a 90kg max weight limit.
Almost equivalent FS rims:
Gravel series FS45/30g (45-30/25): 420g
Revo series 42CM-30T-SUD (42-30/24): 420g
For the record a Schmolke rim would be:
SL 42 clincher/tlr (42-29/22) 450g
On the other hand just like their hubs the rims also very expensive compared to chinese rims.
I was thinking the same thing CK hubs are quite heavy, so the total weight seems to be quite ok considering the hubs are so heavy. if they would use a hub that is as light as a dt 180 those wheels would be sub 1300g
Bont make an aero shoe, the Crono, that was banned by the UCI. Most noticeable difference is a very sculpted heel.
If they tell you something more "sustainable" you can bet that it actually is just about the manufacturing cost.
Ship by air freight n all 🎉
@@PeakTorque Sorry. I forgot that most of the time in the west the only thing they are actually manufacturing is labels (aka. "brands") and not the actual products.
meanwhile the Jumbo-Vismas learned to mount a chain guide while using a 1x12 drivetrain - the dark side aka MTB family knows this like for a while 😂
Why not just use a lockout on the rear shock? Then just a lever can stop the suspension working.
Actually, a french company has invented a process to recycle carbon fiber (or at least to ease up the process of chopping carbon parts and seperating epoxy and fibers).
Where do you find to cycle for so long without coming up against a mountain? I guess that explains the Strava 25km/h average cycling speed, whereas where I live (close to the Peak District) 25 average takes some serious hard work!
Well the front and rear derailleur battery are not interchangeable, therefore not infringing on the patent.
That is one part of the description but not an exclusive claim of sram llc, i think.
Most of the SRAM patents I've read are so specific they are easy to design around.
It seems they have a strategy (and probably staff incentives) to file lots of patents. Probably to ward off the trolls.
Any updates on the upcoming review for Elite Wheels gnar 29 wheelset?
7:00 "I left my bike in the car in Florida and when I went to ride, my Chris King wheels were ovals"
I've got campy carbon cranks on my best road bike and ive got chorus mechanical on my retro Italian classic snd i do like it I don't get the latest campy cassette offering its a bit limited imo. Can get around the cassette limitations but not the RRP
Batteries ain't exchangeable between front and rear . I think that's how they get around srams patent
Sound was fine
Are you riding flared bars or is that just the wide angle of the camera lens? If you are, I would love to know your thoughts of flared bars on a road bike.
Love your geekery man. Any chance you could get a Nich Cycling faith2 or legend4 frameset to check out/ review? Gaining ground here in Thai bit little beyond the borders as yet! Thanks mqn
The gear selection for the plebs always weirds me out, I had to resort to using a 2x GRX crank with my Campy setup because I prefer to spin to win on climbs.
Rotors and loose rivets: This is the first time I've heard of noise being a symptom and haven't had luck looking further. I'm wondering if this could be the cause of my loud SRAM Force rotors. Cleaning and new does not help. Did you talk in more detail about this at some point or can someone suggest what I should be searching for? Thanks!
Agree re Campagnolo. I've ridden Campagnolo for years...10spd record (which was amazing!) 12spd Chorus rim brake & Centeur - which at £600 or less & only 200 grams more than Chorus is amazing! (Again rim not disc). So Campagnolo have IMO cut out a big % of customers & made themselves more like SRAM which costs far less. If/when I go disc it would be hard to stay with Campagnolo given cost/option - remember riding santini gf 2017 & can say 34x29 up the Stelvio with 3000mtrs in the legs is ferkin hard work, would be but easier on a 32
I think Vincenza hit their peak with 9-speed Record though the 11-speed Centaur groupset (sadly no longer in production) I have is pretty damn good. But they're headed way too far in the "Shimagnolo" direction for my tastes though if someone dropped an EKAR-equipped gravel bike on my doorstep I'd happily ride it. Nothing lasts forever and I'm afraid Campagnolo is headed the wrong way with Shimano now in the "even if you have to buy it" category for pro teams as Campy was decades ago. SRAM? I'd walk before I'd use anything with their name on it.
you still can use the 12 speed 11-34 cassettes which from the previous groups - works just as fine
I have a question for the next Truth Show.
I’d argue that you’re the cycling TH-camr most concerned with heat and dissipation. So my question is this: is it safe to run a TPU tube in a rim brake carbon clincher?
Is that Sandside/ Arnside area?
Can you review the new Lwoot Chinese 12 speed electronic groupset it’s only 800$
You showed part of the description of the sram patent publication - the juicy parts are the claims though, they define the scope of protection the patent provides. Let me know if you need any help with the patent stuff in future (patent lawyer here)
Ha i know, but cheers. Inventor on a few patents this end! You'll probably like my next video!
Looking forward to it!
The patent specifies interchangeable batteries between the FD and RD. which the SR WL batteries aren’t. It also specifies a releasable retaining mechanism on the base member of the derailleur. The SR WL batteries themselves have the release, not the derailleurs. Furthermore since the batteries have external contacts for cable based charging, they could potentially be treated as permanently attached.
@@kidsafe great Information! Thank you
Inventor of the wheel and hot water here. I heard there is a patent expert pissing contest I would like to join.
ps: yoog explained it best.
More dyfi laps please... watching your knees is fine and all that... prefer the MTB.
what are you using to record audio and how is there minimal wind noise??
ah lapel mic, is it the rode one?
Lighter, stiffer, more aero... What evs, I was horrified to find the word: 'Campy' on my Ekar. No. Just no. CAMPAG CAMPAG CAMPAG! That horror aside, I've given up racing and have been amazed to find 1X13 does me for road and gravel... If I wanted to be a fussy sod, I'd have two sets of wheels with different cassettes and different tires. But I can't be ar5ed anymore. Loving' it.
Can you not use a chainset of any brand? Or even a regular Campag 53/39 or 52/36?. Also is this hub a new interface or a regular Campag hub
Claiming patent rights on an external battery is like trying to patent rubber brake hoods. Battery has to go somewhere, where’s the novel art of putting it on a derailleur?
Would be interesting to know what's more efficient. Bigger chainrings that naturally come with a lower average cadence or smaller rings but much higher average cadence. In Terms of being biomechanically efficient.
Not quite so. Cadence can be the same, its just a ratio thing front to back. In bigger teeth rings (for the same ratio) the chain tension is slightly lower, supposedly being more efficient.
Does chainline make a difference to efficiency. Using a 50t for the cadence and speed I ride I have a better chain line than being higher on the rear cassette with 53t
@@PeakTorque I see. Instead of having 50/34 and 11-34, it would be more efficient having 54/38 and 15-38. Would be interesting to see what a 105 derailleur with a wolf tooth Roadlink can handle in terms of cassette size.
@@The2808erik 54/15 would be very slow - equates to only 50/14 !!! You would need a 12-38 cassette with 54/38 to reach the same ratio as 11-34 with 50/34
Why not just use a lockout on the mtb? The sram lockout is rock solid and you don’t have to faff with swapping the linkage.
1. Weight?
2. Marketing. Draws attention to the new bike.
It was for a world cup, they're counting all the grams there. For mere mortals the lockout would be more than sufficient.
What microphone is that? Sounds crisp.
The shoes look interesting but they have a really, really narrow tapered toe ... I think this is likely to be less than ideal for the vast majority of people. If your feet are shaped like that, ok. But if not, using those shoes for aero gains is a really bad idea. Also, max size 47 ...
Some of the Pro Flex team did the same thing with rear shocks back in the 90's.
Bring back the flexstem😂
Prices have gotten completely out of hand
profit is not a sound argument for chainring size, as the extra material costs are in cents and a bit of machining extra is marginal
Still, 12.4% is 12.4%. What big corporate is going to say no to that?
@@PeakTorque 12,4% of a small portion of the costs, that's easily compensated by a few more sales
@@MichielvanderMeulen do you work in manufacturing? Because at this volume material cost is significant.
@@PeakTorque Printing machines, solar, injection moulding automation, admittingly not in production factories. But I know aluminum prices. Guess there's a euro or two of material in a chainring of 50 Euro's?
Boa won’t talk to you unless you can meet their 10000pc MOQ.
Engineering wise having a full suspension that doesn't move IS going to break the rear end with regular use. For a one off or for a team that replace bikes regularly then that's fine. But for use every day the rear stays are going to be over stressed and possible damage to bearing housing if they are carbon.
Re: campag prices. It's only marginally more expensive than Shimano Dura-ace (well ok almost a full K more) but cranks won't fall apart . All internals are replaceable and completely wireless with micro switches that are quite robust. Plus a full carbon crank. Upgrading to a carbon crank on a dura ace will mean spending an extra £600-700 on top of the dura ace price.
If you've ever spent some time in a carbon bike factory you'll know they do all the ISO testing and beyond with a fixed rigid steel token. Never a shock. So they're stronger than you think!
@@PeakTorque I haven't been in a factory but have spent 23 years repairing bikes and seen the damage done to carbon and alloy frame from frames not being used with correct shock lengths ect . Things shock mounts braking , bearing mounts becoming damaged ect. The swing arm may hold out fine its more the weak points like pivot and fixing points.
@@edmundscycles1 yeh i guess so. The bonded in hard points are a QC nightmare. I broke 2 Whyte swingarms that disbonded at the bearing seats. The higher end stuff (SC) have in moulded carbon seats which have almost no risk of debonding. In theory... I know the factory who makes that tech and they have very few issues.
You look like you're going 60 kph! What was your road bike 10 time??
Was wondering, as a smaller rider, how much can weight affect a flat TT? I figure having 10, 20, 30kg more weight must help from getting knocked around by gusts, and help maintain momentum? (Yes I'm trying to invent excuses).
I have a question. Can you still pull the brake levers with them angled in so much... It looks like it might be somewhat awkward in the drops😂
Dont ride in the drops on road bike TT. Throwing away watts 😊. But yes, i can, its fine.
@Peak Torque riding in drops on road bike is throwing watts away?
If you can get your forearms level on the hoods but not in the drops, hoods is more aero.
@@Dolmar-Rick yes. Forearms horizontal is 15w faster for me at 40kmh than in the drops. So i set this bike up for that. I don't ride it much apart from the odd race/TT at the moment mainly riding MTB. If i was doing big 100km+ days i might readjust but honestly I've got pretty used to this position now.
@@Dolmar-Rick Keep you shoulders tight together if you want to save energy.
Roglic used a 40 tooth chainring
On the front? Seems small even with a 10t
What's your source on that? I just read he may have used a 46t! But doesn't seem possible.
How is he filming this?
Velo Vetta : th-cam.com/video/XnwLfkp8x1c/w-d-xo.html
(Did not find it in the description as advertised).
Thanks, i forgot to add it!
Love these videos! Wonder if UAE are using center lock for quicker rotor changes?
Why would you need quick rotor changes?
Think its just because the enve hubs are centerlock.
@@MrBusunglueck I think for a small cadre of mechanics maintaining 40+ bikes and 3x as many wheels over a grand tour, it makes a difference.
And personally, removing and installing a lockring vs six tiny bolts, is much preferred when I need to work on my own wheels.
@@Dobiecx Yea but usually you dont have to change any brake rotors during a grand tour. Time is not an issue.
Yes if you're super strong on your bike you can climb anything on a 10 x 25 with a 50 tooth chainring 😂
Either your grips are not at the same Hight on your bars, or your camera is not centered. It looks like the drive side grip is lower.
what jersey is that mate
A black one
Spexcel on Ali E. Solid.
@@PeakTorque pretiate it big man
1) anyone else bugged by the fact that PT's handlebars look too wide? Could just be the camera angle though. 2) I suspect that the fact that the batteries aren't interchangeable and they clip on in a goofy way is how Campy skirts SRAM's patents
They're 38cm bruv 😂
@@PeakTorque yep. Camera angle then
A 50 - 10 LOOOOL I find an 11 already riding horrific. I stick to my mechanical shifting for a bit longer. F$@& this stupid developments (like one by).
34 - 34 = rimkiller
Campagnolo is outdated and overpriced.
Your hoods are uneven in height. Intentional?
Also do you have a source for the claim that YBN makes the Campy chains? I was under the impression Campy went in house starting with 10speed.
They're not uneven. I am looking at it right now, I think I'd know...
I think it was in the 10-speed era that I was at the Campagnolo HQ in Vicenza and saw the machines used to make chains. They made a big deal about changing from an outside maker (Rohloff?) at the time, but I have no clue as to what they're doing now...their cave-in to a quick-link makes me wonder what changed? They used to be rock-solid against such things. But their stuff didn't used to look like Shimano designed it either, so...
The carbon splined discs... Yeah! Put a cracking material where your braking is. What you have to do when you go for an inferior braking system.
If they wanted inferior braking system, they'd be using rim brakes
@@dainiusvysniauskas2049 Yeah. Superiority is the reason they got to apply the breaking force to an oversized hub and a too stiff fork and wheel at a disadvantageous lever inducing overheating problems, in a system which has the tendency to fail in catastrophic ways. The superiority of course is that now you can lock up your wheel twice as easy. But you solve some imaginary breaking problems in the wet of the classical time tested solution, which was far less costly more reliable and almost maintenance free. Why don't you just put lead weights on your bike? Sure.
@@rosomak8244 Careful, your inner durian rider is leaking, you should seek help before you turn into the guy full time.
Instead of random bullshit that you spew without any knowledge behind it, let's talk about facts:
1. Disc brakes have better modality.
2. Disc brakes do not require as much force applied on brake levers.
Are bikes with disc brakes heavier? Yes, by 300-400 grams. Is that weight significant in any way or form? No, unless all you literally do is climb 10%+ hills and then take a helicopter ride home.
Can disc brakes fail? Yes, but so can rim brakes, especially considering that rim brakes literally wear down your rims (unless you propose stopping all the time to clean brake pads).
Are disc brakes better in the wet? Yes, especially with carbon wheels.
Do disc brakes require maintenance? Yes, but so do rim brakes - pads and braking surface have to be cleaned periodically to prevent premature wear on the rims, cables and their housing get just as much as with mechanical disc brakes.
You're mentioning stiff forks, but let's not ignore stuff like rim brakes being a limiting factor when designing wheels
FIRST!
Nice bro
When you try to replicate bicyclerollingresistancecom's results on the road using the cda sensor, wouldn't you also measure the vibrational losses, which are probably not fully accounted for in their testing? I'd expect lower tire pressures to perform far better than higher ones, when compared to their testing. I also expect tires with harder/enforced casings to perform worse when compared to their testing. I'll be looking forward to the results!
Yes correct. Vibrational losses come in to play for sure, but for this test we'll try and iso that by using standard skin stress (pressure/cross section).
Ugly and expensive
It is about time exclusively drive train campy for the few! I am ordering 4 sets! 😊. Look I will say stop making judgements on chain rings and cogs. Let an actual pro rider use it and give a professional opinion. Other than that I wouldn’t believe what you said or others say. To my point your review has no valid point… I retired from cycling, but I think reviews should be left to professionals only.
"but I think reviews should be left to professionals only" And you would qualify/designate them how?
IMHO Hambini and Peak Torque might be as close as you're gonna get to "Consumer Reports" on cycling stuff.
Are there others out there with no axe to grind or secret profits to be made honestly reviewing cycling stuff? It's damn hard to tell.
That intro, very below your best.
Bring back Hambini.
Everybody knows the rules.
Can someone please donate some rovals as everyone says they’re the most aero wheels and I would love to test them
