The Commencal Factory team were spotted racing a brand new downhill bike at the opening round of the 2021 World Cup Downhill series this weekend in Leogang. Second and third placed Thibault Daprela and Amaury Pierron were seen aboard the prototype Commencal Supreme with a rather complex-looking virtual high pivot suspension platform. Here’s what we know so far. Cory spotted the prototype in the pits at Leogang. Commencal Supreme Prototype DH Bike

Let’s start with the little that we do know about the prototype Supreme, before moving on to the realms of hypothesis and somewhat educated guesswork. It’s a mullet

It has an aluminium frame (for now)

Commencal have no immediate plans for production

You’ll notice that everything looks a bit clunky just now, with unrefined pieces of hardware dotted about the bike allowing the Commencal engineers to continually experiment with their take on a virtual high pivot suspension linkage.

There is a lot to get your head around here. And, without non-driveside images of the suspension linkage, we can do little more than guess at what exactly lies behind the CNC machined plate supporting the chain idler. But, we can tell you there are at least three sets of pivot bearings nestled in behind there.

Connecting that triad of pivots to the rocker is what looks to be a CNC machined brace plate that itself has two potential upper mounting points. These likely alter the leverage curve slightly and allow Commencal and their riders to experiment with different setups quickly […]
