Is aero derailleur cages being worth their money a proven thing? Larger pulley wheels are sold under the claim that they save power through less chain articulation (which is true, but likely very negligible...).
With all the turbulence behind the rider you could likely have a bolt sticking out the derailleur by a few cm and not notice it drag wise.
Proven? No. But there is a legitimacy to the claim.
Because a road race is 6 hours, any insanely tiny gain of 0.01W CAN be perceived to be significant at the end of race.
If your competitor has to expend 3500 calories and you only 3450 calories to ride the same time that will add up over a tour of even 7 days, let alone 21 days.
In DH though, the bikes are already so draggy, the only aero to be made is the rider, and most if that is from body position anyway.

100% The rider must have a feel while using the rear brake they are trying to get. The was a rumor that Danny Hart was looking for something specific while riding this bike.
Valli on the new Tues with high pivot chain guide. I wonder if they will sell that as an add on.

I think it's a workaround for the relatively high levels of anti-squat on the new model. I was surprised to read the press release and how high the AS is on the new bike, but they also open their copy by talking about how their goal wasn't to make the fastest race bike, but something more versatile. I thought that was odd, but maybe YT made a conscious choice to subordinate their team riders desires for a more pedal-able, "poppy" bike for general population bike park use. YT riders have been using Ochain for a long time, and this idler looks like an attempt to solve the same problem.

could be, but kinda odd to make a „not so racey“ DH-race bike… to me the new tues is a total letdown. first the diaper to suggest something new and different is coming but the end result is basically a mullet version of the old bike with bumpstops added to the frame. geo is mostly the same except flipchip and on the conservative side.
look what others are doing like canyon, pivot, norco, even the new V10 is more different.

Does it looks like like oval chainstay is on Amaury’s frame compared to rectangle? Also an axle mount to chainstay option vs stock is mounted to seatstay.
Here's another thought on Amaury's steel oval-shaped chainstay. The obvious conclusion is that they're chasing a particular amount of flex that they couldn't get out of aluminum, but here's another idea: What if they already had the level of flex they wanted out of the old bike, but they were breaking aluminum chainstays left and right? It makes sense that the chainstay would be the weak point in a flexy rear end, because it's the direct line from the bottom bracket (aka where most of the rider's mass is transmitted to the rest of the chassis) to the rear axle (the primary load-bearing wheel in violent turns). Steel has a much, much higher fatigue life cycle than aluminum, and would allow the chainstay to flex and flex all day long without breaking, like a leaf spring or torsion bar. Obviously the steel one still has welds, but I'd wager a welded steel leaf spring has a much higher fatigue life cycle than a welded aluminum leaf spring.
This thread is great! Been following since page 100ish and so glad it’s reached 600! Great work, your collected knowledge has given me the edge several times, keep it up!

I would agree, except for the fact that the frames are replaced so regularly anyway because of fatigue and cracking everywhere. This isn't a dig at commencal but I'd imagine each rider would go through 4+ frames during a season. I know teams that have used 6+ and Neko admitted to cracking 12 frames in a season.
Now, not all the failures are going to happen on the chainstays, in fact most won't. So great theory, but it doesn't really make sense as they'll swap the whole rest of the bike regularly anyway.

What I'm suggesting is: what if a disproportionate, predictable, and inconvenient amount of failures are happening at the chainstay? For instance, imagine a rider going through 4 front triangles in a whole season but replacing 4 chainstays in a single weekend. I'm not suggesting that all those failures would be big, catastrophic, run-ending failures, but if there are cracks consistently forming at the welds over and over again throughout a weekend and you have to be swapping chainstays constantly, that's a major PITA for the riders and mechanics. And what if there was a simple way to fix that by switching materials? Carbon would also be good for flex/durability, but would go against the Commencal "all metal, all the time" ethos.
How long before Commencal throws away that ethos in pursuit of ultimate performance? They seem to be investing into the development of the platform (frame) a lot, one of the top 3 on the circuit?

Sorry I misunderstood before. That's a very valid theory.
I reckon it's still flex based, as they were testing pre steel stays with the adjustable seat stay bridge on the frame.
Someone posted a photo of the pivot moved to the seat stay a couple pages back too, that would totally change the entire suspension package.
The steel/alu/carbon flex characteristics are certainly the next frontier of MTB frames, gone are the days of stiffer is better.

going back to helmet rumors, many Alpinestars riders in Fort William are wearing the helmet that looks like the MX one. I guess it is indeed the nex DH version. Also, Canyon Pirelli riders are using what looks like a new helmet from Dainese. Chinguard looks very similar to the old AGV MX helmet.
I was watching Bruni's Gopro footage from Fort William practice, and something caught my eye. From the footage you can actually see when he switches between damping modes from the LEDs on his stem. It happens at least 3 times: 1) blue mode off the start till at least the wood section (I did not check if he switches anything in the upper section); 2) green mode in the wood section until the second turn/shark fin after the road gap; 3) back to blue mode for the new fast section; 4) red mode from the bridge before the motorway to the finish. I think this proves that it's not just a "firm mode" switch. I guess the RS flight attendant does the same thing, but automatically. I wonder how different the damping can be between the modes.

Really cool to see that he has 3 options, just wonder what changes those are doing.
While on the Loic topic, I noticed he’s running split lower clamps like motocross bikes. Could be flex character he likes or just more even clamping for the stanchions the way the torque is distributed.

Did you see the button in the right side of the bar, assuming going to the fork?
big fan of that markings on the bar and stem, makes setup super easy. why doesn‘t everyone deliver something like this?
I will never buy another set of deity bars because of this. So annoying.
Also shoutout to TAG metals for their all mountain stem having slots to mark your steer tube when you get that perfect alignment. Makes realigning so much faster.
so rad all the tech gizmos! (well i think so). in semi-finals today, troy, finn and loic top 3, all with electronics. separated by just .071 seconds. luca was 4th only .5 off first place. did he have flight attendant too?

Not sure if they have in-house Aluminum fab capabilities.
