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!

The 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.Angel Suarez's Supreme DH View a full gallery of both bikes, here
