​@@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.

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.

[@RyonBeachner]

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!

[@kitten-inside]

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.

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.

[@lleweybyrne]

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!

[@lincolnlu9869]

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.

[@AGENDA_1938]

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...

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.

[@PeakTorque]

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.

[@glennoc8585]

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.

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.

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

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.

[@PeakTorque]

They're not uneven. I am looking at it right now, I think I'd know...

FIRST!

Nice bro

[@juanhidalgo7043]

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.

Can someone please donate some rovals as everyone says they’re the most aero wheels and I would love to test them

[@shawnsmith7009]

That intro, very below your best. Bring back Hambini. Everybody knows the rules.

Ugly and expensive

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!

[@PeakTorque]

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).
