Summary
The Commençal Supreme excels in downhill and enduro performance with its innovative HPP suspension system, providing exceptional bump absorption, stability, and grip on rough terrain. However, it can feel heavy and less efficient on flatter trails, with some models experiencing pedal kickback. It is praised for its value and race-ready capabilities but may not suit all riders due to its specialized nature.
Incredible bump taming and high-speed performance
Innovative HPP suspension design for stability and grip
Good value with solid components
Available in multiple wheel sizes for versatility
Ready for racing out of the box
Heavy and draggy when pedaling
Short reach and less playful handling
Pedal kickback in some models
Requires adaptation to maximize performance
Not suitable for all terrains or rider preferences
The capacity of the rear end to swallow up punishment is gob smacking.
It’s a bike that finds it easy to make up speed in rough areas all with unparalleled stability. It’s trademark: speed.
Charging into rough rock gardens and braking bumps is unreal - I tried a section in Pila faster and faster, and the Supreme was the first bike I have ever ridden that genuinely became easier to handle the harder I pushed it.Pinkbike

Jul 2018 · Paul Aston
The Supreme was ready to ride out of the box, I changed down a spring weight on the Fox DHX2 shock from 450lb to 400lb, pumped up the fork to 76psi, opened up most of the compression front and rear, and set the rebound on the fast side with a couple of extra clicks on the shock's HSR to for a little more control under big hits..
Unbeatable bump and high-speed performance
Ready to go racing out of the box
Great price and specification
Requires some adaptation to get the best out of the bike
Falls off chairlifts and shuttle trailers and might not fit in your car or garage
May make you ride too fast for your own safety

Commencal commits to 29, releasing the big wheeled version of their World Cup proven Supreme DH.

While most 180mm bikes are targeted towards the gravity racing realm, Commencal took a different approach with the new Supreme SX. - Mtbr.com

Mind blowing rough terrain performance, but it could do with a bit more length and a diet. Buy if you want to hit the roughest and toughest descents and don’t care about pedalling performance
Incredible bump taming performance with a solid parts package
Short reach, draggy when pedalling and rather hefty too
