Commencal has unveiled its new race bike for the 2021 season.
We've
spotted this bike at a few events this year and it seems our suspicions were correct about a new suspension design. Most of the frame tubing is apparently lifted from the current Supreme but it now uses a "Virtual High Pivot" system, a substantial departure from the high single pivot that the brand has used to so much success in the past few years.
PB tech editor Dan Roberts has sketched the above diagram to explain the new 6 bar system and will be doing a more in-depth analysis of it tomorrow. The purple link is essential otherwise the rear wheel would move around without the upper link (light green) moving and compressing the shock.
We also noticed that there’s plenty of adjustability in the system with the purple link being adjustable in length, which could enable Commencal to change the geometry and kinematic, and different mounting points on the upper link (light green) to further adjust how the kinematic behaves through its travel. The idler has now also moved from the swing arm to the mainframe thanks to large metal plate.
It’s worth saying these are just our best guesses from what we can decipher from the photos. Commencal didn’t provide us with non-drive side shots, which makes a proper analysis difficult, but we’ll be on the hunt for some clearer shots at Leogang this weekend.
Also interesting is that this may be a racer-only bike for the foreseeable future as Commencal says there is "no commercialisation on the cards yet".
Press Release: Commencal
We are proud to present our new Commencal Supreme!
It's a prototype, a lab bike that means we can try many new concepts under the most testing and extreme conditions.
In order to work with a minimum of unknowns, we use a lot of tubes from our current bikes and this allows us to ensure perfect management of stiffness as well as limiting the risks in terms of resistance. This Supreme features a brand new kinematic with a Virtual High Pivot. Through this system, we're always looking for more performance and liveliness, without compromising the capacity of our now renowned High Pivot Point.
There is no commercialisation on the cards yet, however it’s sure that this is the dawn of a new era for the future of Commencal DH.
You will be able to enjoy Amaury, Myriam, Thibault and Angel behind the handlebars for the whole season!
That's all the info we have for now but enjoy these photos of the team's race bikes ahead of the season opener this weekend.
Amaury Pierron's Supreme DHThe routing has been changed so that the cables now come out the top of the toptube/ seat tube area, drop through the new linkage and re-enter into the chainstays.

Would love to see a video of the suspension cycling though, this is definitely a confusing one!
*(wheel via seat-stay pushes rocker, rocker pulls dog bone, dog bone extends chain-stay)
I'm gonna hold out for the 7 bar extra high pivot system before I upgrade...
Interesting mx insurgent.
Quite surprised they didnt skip that and do an E.

Will be interesting this weekend with a few riders changing teams and commencal effectively changing bike.
It's what's going to make this weekend interesting. With Bruni having a wee injury, new Commencal, Hart Inna new bike, Homan coming Breeden finally injury free coming into a season and Inna new bike, the new Mondraker, Reece not showing his hand apart from on the golf course .. , etc
Commencal: "Hold my baguette".
Help yourself for God sake. Brits always find a good solution... for them indeed.
PS: since when does UK care about food (proper food)? (private harmless joke, sorry)
We have great curry houses, Chinese restaurants, sushi bars, Italian pizzerias, German smokehouses, French boulangeries...
This is quite like a horst-link version of the Equilink, which was somewhat like a linkage-driven "single-virtual-pivot", in that the wheel path is only defined by the short-links. As opposed to this new bike also having the horst-style chainstay pivot at the dropouts defining the path as well.
Interesting!
I cannot see a production Commencal with so many pivots in the frame.

Off course no other sport moves so much the dampers as downhill or enduro, and has way too shitty sprung to unsprung weight ratio of the equipment and lack of other things to add so it can be done.
But in my perception, adding linkage and pivots to move the wheel certain way is bullcrap. The only linkage that have beneficial impact is the shock linkage to tune how the bike will react to impacts. It's the beauty of the 2020 supreme, the beaty of the Evil, Kona, and some others.
Looks like a bike: Check
Rocks: Check
I hope not because I think most would appreciate that.
"Adjustable chainstays point to this being a prototype bike that will be dialled in over the season"
A big place the rearward path helps is a huck into a rock garden. Get that rearward action to extend the wheelbase right from the top of the travel as you touchdown in a bunch of jank, nice and stable. This opens up line choice since you worry less about getting hung up on anything in the landing zones.
Looks fussy to clean, blah blah blah lots of bearings blah blah blah FAST AF!!!!!!!!!
Commencalized?
150/157 is foolish for a DH race bike.
