Spotted: Amaury Pierron is Racing a Prototype Commencal DH Bike

Apr 12, 2021
by Daniel Sapp  

It appears that Commencal may have a new DH ride in the works judging by Loic Bruni's Instagram story this weekend from Spain at the 4 Rider's Bike Park. The bike was well covered up but it appears that the rear end has undergone some major updating.

Comparing the current Supreme DH and the bike Pierron is riding, the stays and linkage are different with the new seatstays running straight. Most telling, there's also now a pivot on the chainstay. Now, at first thought, the axle placement screams Horst link but, it does appear to be more of a conventional chainline than a high-pivot so it could be a bike park bike of sorts like Commencal's Clash, rather than a high-pivot race bike. We have heard that there's still an idler pulley but, it's a bit different placement and lower than the Supreme's.

Our best guess at the moment? It's still a single high-pivot system but with a shock more in a tunnel through the seat tube and the chainstays are one of the links that goes to compress the shock. One more bit of noteworthiness, the chainstay length appears to be adjustable at the axle.

Big differences between the current and prototype in the back end.

Another photo we found gives a better look at the chainstay style pivot and adjustable chainstay as Pierron is folding his rear tire over in a turn.

We've reached out to Commencal to see if they have any other details to share and we'll keep our eyes open and provide an update if and when more information emerges.

 How's it still gonna be a single pivot with the new pivot on the chainstays?
  • 9 1
 The main pivot could very well be on the seat stay. I am working on a bike like this, there are a couple renderings in my profile. Not claiming it is my idea, just can't think of any other bike with this setup right now...
  • 4 0
 @SleepingAwake: The Zerode G1 and G2 had that system. The later versions of the I-drive bikes were doing something similar to that also.
  • 3 1
 It's going to be a seat stay pivot, with the chain stay actuating the shock linkage like on a DeVinci Wilson. They might've run into some tuning limits of the old linkage. I'm surprised the brake is still mounted to the seat-stay as that continues with the very high anti-squat of the old bike. Mounting on the chain stay (again like the Wilson) would allow tuning of the anti-squat to lower values. Makes me wonder if anti-squat values >100% are the way of the future and part of the Supreme's secret sauce.

  • 3 0
 @justinc5716: I think you mean anti-rise (aka brake squat), but I totally agree with you on both fronts. I'm sure this design iteration is primarily based around how the linkage drives the shock, not the axle path. I'm betting it's still a high single pivot bike. I also think higher anti-rise numbers might just be the trend of the future.

 @CustardCountry: never actually ridden it. Was more to figure out if bladder Inflation moulding in composite moulds would work. Gonna make one for the diy mtb tho

 @grizzlyatom: Yes, anti-rise. Thanks for the catch.
  • 3 0
 It's like a linkage-driven single pivot, but upside down. Instead of the chainstays as the fixed swingarm and a pivot on the seatstays, the seatstays are the fixed swingarm to give a high pivot, and there is a pivot on the chainstays that drive the shock.
  • 1 0
 @SleepingAwake: Any particular reason why you chose to put the rear pivot concentric to the axle? Wouldn´t it be beneficial for packaging to put it in the seatstay like commencal has seemingly done? Shouldn´t effect suspension much, or am I missing something?
  • 2 0
 @F22: yes the idea is to make sure the brake torque does not influence the suspension movement. I already have a high amount of anti-rise with the high pivot design, and as I understand it this could to some degree be counteracted with a different pivot placement, but honestly the whole brake side of suspension is still somewhat of a black box and this neutral starting point made the most sense to me.

 @SleepingAwake: Holy crap! That looks amazing! Good work!!

 @SleepingAwake: thank you for designing actually wonderfully looking bikes. I applaud anybody doing something on their own but there’s a bit too much whacky steel tubing made by folks who claim their stuff is superior and it looks like it because there were no compromises taken when it comes to geometry and suspension action. Lousy excuse really. Bikes like Zerode Taniwha or Forbidden Druid are excellent examples of taking a unique approach and making it look really good in the process. Then you have BTR and Swarf who took time to make something appealing out of what normally would end up as an ugly duckling. Same with Kingdom Void, they really refined the design. It may be that Steam Punk is just not my thing.

Wonderful bike!

 Yall are off the mark. That thing is for big Aero gains , plus strong ground effect for extra grip. Next up is a big fast and furious spoiler on the rear axle.
Maybe turbofan wheels for brake cooling?

 So, it has chainstay pivot, but you still think it's a single pivot? Wtf?
  • 2 0
 It is if the main pivot acts on the seat stay and the chain stay drives the shock. Kind of like the split pivot Devinci Wilson but without the linkage being concentric to the axle.
  • 2 1
 Ever hear of the Devinci Wilson?
  • 2 1
 @ninjatarian: Devinci Wilson is a split-pivot. It has a pivot not on chainstay, but on the rear axle. It's something completely different.

I get that it might be that the main pivot is really on seatstay and it is kind of reversed faux-bar (single pivot with an extra link). But why would they do it?
