How it compares

200–203 mm at the fork almost exactly matches the 200 mm median of the 16 bikes in the “downhill bike” category in our database. Among Commencal’s mountain bikes, the Commencal Supreme DH V5 is the model with the most fork travel. The frame is made of aluminium.

Depending on the build, fork and shock come from FOX and RockShox. The fork line-up ranges from the FOX 40 Performance to the ROCKSHOX Boxxer Ultimate. The Essential build uses a coil shock (FOX DHX 2 Performance Elite), so SAG is set with the spring rate rather than air pressure. Wheel sizes differ by build or frame size: 27.5 / MX.

Setup notes for this spec

Air fork (FOX 40 Performance): the air valve is on top of the left leg under a cap. Change pressure in small steps (about 5 psi (0.34 bar)) and cycle the fork a few times afterwards so the air chambers can equalise.
Rebound: turn the red FOX and RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
Coil spring (FOX DHX 2 Performance Elite): if SAG is off, only a different spring rate will fix it. Preload should just keep the spring from rattling; more preload makes the shock less supple.
Air shock (ROCKSHOX Super Deluxe Select R): measure SAG in your riding position, ideally with a helper holding the bike. Cycle the shock a few times after every pressure change.

Target SAG for the Commencal Supreme DH V5

SAG is the share of travel your weight already uses in the riding position. The table gives it straight in millimetres – read the O-ring on the stanchion and on the shock shaft and adjust the air pressure until it matches. Any figures from Commencal take priority.

203 mm fork, 75.0 mm shock stroke (Essential)

Riding style	Fork SAG	Shock SAG
XC / touring	17 % = 35 mm	24 % = 18.0 mm on the shock shaft
Trail	20 % = 41 mm	28 % = 21.0 mm on the shock shaft
Enduro / rough	22 % = 45 mm	30 % = 22.5 mm on the shock shaft
Bike park	20 % = 41 mm	27 % = 20.2 mm on the shock shaft

200 mm fork, 75.0 mm shock stroke (Ride, Ride, Ride 2026, XS 2026)

Riding style	Fork SAG	Shock SAG
XC / touring	17 % = 34 mm	24 % = 18.0 mm on the shock shaft
Trail	20 % = 40 mm	28 % = 21.0 mm on the shock shaft
Enduro / rough	22 % = 44 mm	30 % = 22.5 mm on the shock shaft
Bike park	20 % = 40 mm	27 % = 20.2 mm on the shock shaft

How to measure SAG is explained in our guide SAG setup.

Tyre pressure starting values

For 2.40″ wide tyres, tubeless with a trail casing. With an inner tube about 0.2 bar (2.9 psi) more, with an insert about 0.1 bar (1.5 psi) less. Stock tyres: Rear: MAXXIS DHR II - Front: MAXXIS Assegai; Rear: MAXXIS Minion DHR II - Front: MAXXIS Assegai.

Ready-to-ride weight	Front	Rear
60 kg	1.43 bar (21 psi)	1.63 bar (24 psi)
70 kg	1.55 bar (22 psi)	1.75 bar (25 psi)
80 kg	1.67 bar (24 psi)	1.87 bar (27 psi)
90 kg	1.79 bar (26 psi)	1.99 bar (29 psi)
100 kg	1.91 bar (28 psi)	2.11 bar (31 psi)
110 kg	2.03 bar (29 psi)	2.23 bar (32 psi)
120 kg	2.15 bar (31 psi)	2.35 bar (34 psi)

Air pressure in the fork and shock

You will find a guide value for air pressure on the fork sticker (or on the shock) or in the suspension makers’ charts. Our calculator also takes riding style and rebound into account. In the end, measured SAG is what counts.

Note: all values without guarantee. Specification can vary by model year, frame size and market – if in doubt, the type plate, the manual and Commencal’s information apply. Never exceed maximum pressures.
