How it compares
With 200 mm at the fork, the Commencal FRS sits above average: across the 12 bikes in the “freeride bike” category in our database, the median is 180 mm. Front and rear both work with 200 mm of travel. Among Commencal’s mountain bikes, the Commencal FRS is the model with the most fork travel. Commencal builds the frame from aluminium.
Depending on the build, fork and shock come from FOX and RockShox. The fork line-up ranges from the ROCKSHOX BOXXER Base to the FOX 40 Factory. The Park 2026 build uses a coil shock (ROCKSHOX VIVID Coil Base), so SAG is set with the spring rate rather than air pressure.
Setup notes for this spec
- Air fork (ROCKSHOX BOXXER Base): 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 shock (ROCKSHOX VIVID Coil Base): SAG is determined by the spring rate. Only add enough preload to stop the spring from rattling.
- Air shock (FOX Float X2 Factory): 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 FRS
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.
200 mm fork, 75.0 mm shock stroke (Park 2026, Ride, Rockshox 2026, Signature 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
The values apply to 2.50″ wide tubeless tyres with a trail casing. With an inner tube add about 0.2 bar (2.9 psi), with an insert take off about 0.1 bar (1.5 psi). Stock tyres: Rear : SCHWALBE Tacky Chan - Front : SCHWALBE Magic Mary; Rear: MAXXIS DHR II - Front: MAXXIS DHR II; Rear: MAXXIS Minion DHRII - Front: MAXXIS Assegai; SCHWALBE Magic Mary.
| 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.
