How it compares
On travel, the Vitus Sommet is right where the “enduro bike” category usually is: 170 mm up front against a median of 170 mm from 41 bikes. On travel, it slots in between the Vitus Escarpe and the Vitus Dominer in the Vitus range. The frame is made of carbon.
For suspension, Vitus combines components from FOX and RockShox. The fork line-up ranges from the RockShox Domain RC to the RockShox Zeb Ultimate. Wheel sizes differ by build or frame size: 29 / MX.
Setup notes for this spec
- Air fork (RockShox Domain RC): 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: on FOX and RockShox suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
- 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 Vitus Sommet
Instead of percentages, this table gives SAG directly in millimetres, measurable with the O-ring on the stanchion and on the shock shaft. Change the pressure step by step until you reach the value; if Vitus gives its own target SAG, use that.
170 mm fork, 62.5 mm shock stroke (290 CR, 290 CRS, 290 CRX)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 29 mm | 24 % = 15.0 mm on the shock shaft |
| Trail | 20 % = 34 mm | 28 % = 17.5 mm on the shock shaft |
| Enduro / rough | 22 % = 37 mm | 30 % = 18.8 mm on the shock shaft |
| Bike park | 20 % = 34 mm | 27 % = 16.9 mm on the shock shaft |
170 mm fork, 65.0 mm shock stroke (297 AMP, 297 CR, 297 CRS, 297 CRX)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 29 mm | 24 % = 15.6 mm on the shock shaft |
| Trail | 20 % = 34 mm | 28 % = 18.2 mm on the shock shaft |
| Enduro / rough | 22 % = 37 mm | 30 % = 19.5 mm on the shock shaft |
| Bike park | 20 % = 34 mm | 27 % = 17.6 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
For 2.50″ 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: 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 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.
