All builds
Fork, shock, shock size (eye-to-eye length × stroke) and rear travel, weight and price according to the manufacturer. Wheel size: MX.

How it compares
200 mm at the fork almost exactly matches the 200 mm median of the 16 bikes in the “downhill bike” category in our database. Front and rear both work with 200 mm of travel. Among Vitus’s mountain bikes, the Vitus Dominer is the model with the most fork travel. Vitus builds the frame from aluminium.
Vitus uses RockShox suspension throughout. The 297 build uses a coil shock (RockShox Super Deluxe Select R Coil), so SAG is set with the spring rate rather than air pressure.
Setup notes for this spec
- Fork (RockShox BoXXer Select): air goes in through the valve on top of the left leg. After every change, compress the fork firmly a few times before measuring SAG.
- Rebound: turn the red RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
- Coil spring (RockShox Super Deluxe Select R Coil): 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.
Target SAG for the Vitus Dominer
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 Vitus take priority.
200 mm fork, 72.5 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 34 mm | 24 % = 17.4 mm on the shock shaft |
| Trail | 20 % = 40 mm | 28 % = 20.3 mm on the shock shaft |
| Enduro / rough | 22 % = 44 mm | 30 % = 21.8 mm on the shock shaft |
| Bike park | 20 % = 40 mm | 27 % = 19.6 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
Basis: 2.50″ tyre width, tubeless, trail casing. If you run tubes, add about 0.2 bar (2.9 psi); with an insert, about 0.1 bar (1.5 psi) less is enough. Stock tyres: Maxxis Assegai / Maxxis Minion DHR II.
| 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 suitable starting pressure on the sticker on the fork stanchion (or on the shock) or in the suspension manufacturers’ setup charts. Our calculator gives you a starting value including rebound for your weight and riding style. What matters afterwards is the measured SAG from the table above.
