Commencal Refines the Supreme DH V5.2 to Make It Faster Than Ever

The Supreme DH is the bike that built Commencal’s reputation — across its generations it has racked up 55 Elite World Cup victories, which the brand bills as the most successful downhill bike in the sport’s history. So when an update lands, the question is always how much to change. The answer with the V5.2 is: deliberately not much.

Rather than a clean-sheet redesign, Commencal kept the V5’s travel, mullet wheel format and adjustable race geometry and concentrated on the two things that decide a downhill run — how the suspension behaves over rough ground, and how it behaves under braking. As Bikerumor’s launch coverage put it, the goal was to make “one of the winningest downhill bikes faster than ever” rather than reinvent it.

The Supreme has long run a high-pivot, idler-pulley suspension layout Commencal calls HVCS — the High Virtual Contact System — a six-bar design that lets the rear wheel travel up and rearward through bumps for a planted, fast feel. For the V5.2 the engineers left the broad architecture alone but relocated the virtual pivot point near the rear axle from the chainstay to the seatstay.

That sounds like a small move, but it changes how the linkage builds support through the stroke. Commencal’s claim is more mid-stroke support and a more direct response on fast, smooth sections, while staying composed and comfortable when the track gets rough. The frame keeps its existing tuning tricks too: a flip-chip with four kinematic settings and a removable brace between the seatstays to dial rear-end stiffness.

The second big change is the rear brake. Commencal has moved the caliper mount to a new position — tucked between the chainstay and seatstay — specifically to work with the HVCS 2.0 kinematics so the suspension stays active while you’re hard on the brakes, reducing the weight transfer onto the front wheel that can wash a front tyre in a steep, rough corner. The frame takes rotors up to 223 mm.

Around that sit the housekeeping upgrades: the V5.2 adopts the UDH standard so it runs the latest drivetrains including SRAM’s XX DH T-Type; cable routing now enters through the head tube for a cleaner look, better sealing against water and dirt, and quicker race-weekend maintenance; and a new generation of dual-density “Silent Mode” chainstay and seatstay protectors aims to kill chain slap and drivetrain noise without affecting the suspension. The frame is aluminium and carries EFBE’s top gravity certification, with a lifetime warranty against manufacturing defects for the original owner.
