Commencal’s new Downhill mountain bike comes in mullet form with a 29″ wheel up front and a 27.5″ wheel out back. Before we say anything about it, please allow Amaury Pierron’s shredding to do the talking. This man’s bike riding aboard the Commencal Supreme Mullet is truly something to behold. No music required, no fancy camera work; just pure unadulterated insane shredding in the “Sound of Supreme Speed”.

Commencal’s new downhill mountain bike comes in mullet form with a 29″ wheel up front and a 27.5″ wheel out back. Following the 2018 change in the UCI regulations for downhill mountain biking wheel sizes, Commencal got to work on the development of a mullet downhill bike.

Commencal were definitely not stoked on their first attempt. It simply could not compete with the refined 27.5″ or 29″ Supreme bikes. For the 2019 season, Commencal’s race teams put the idea of a mullet bike on the back-burner, concentrating instead on optimizing the efficiency of the existing platforms. The Commencal engineers continued development behind the scenes.

In November 2019, Commencal gave the first Supreme 29/27 bikes to Commencal/Muc-Off team riders. Their feedback was this: “The bike was more stable and faster than a 27.5-inch, and more agile and dynamic than a 29-inch”.

Several months of lap times and data acquisition on a multitude of different tracks later, Commencal came to the conclusion the Supreme Mullet (even if it is perhaps not suitable for all sizes of rider) seemed to be the ideal bike for many of their pro racers. Amaury Pierron being one of them.

The result

The Commencal Supreme Mullet DH bike rocks 200 mm of rear wheel and fork travel. The bike sees new kinematics and a new main pivot point built around the mixed wheel sizes. The idler pulley also changes position to allow for increased pedaling efficiency.

The Commencal Supreme Mullet runs a 63.5° head angle and a 67° seat tube angle. Seat tubes measure up at 400 mm across the S-XL frame size range. The chainstay measures 448 mm in Small, but the Medium, Large and XL frames all have a chainstay length of 456 mm.

Reach extends from 435 mm in Small up to 505 mm in XL. The BB drops 9 mm from the rear wheel axle on the small frame, but only 4 mm for the larger frame sizes.

not only a high pivot system works great, but it also has a certain reminiscence to those old Vouilloz bikes, engineered by Olivier Bossard, right after the Sunn times. Glad to see a high pivot in Commencal bikes now, glad to see a small brand fighting against big dogs like specialized and santa. Would be great to have in on a commencal trail bike. Also would be great if commencal bikes were a tiny bit lighter.
