How it compares
At 110 mm, fork travel is 10 mm shorter than the median of the “cross-country full-suspension bike” category (120 mm, 23 bikes). The rear offers 80 mm, 30 mm less than the front. Within Trek’s mountain bikes, it sits between the Trek Marlin and the Trek Procaliber on travel. The frame is made of carbon.
The starting price of €3,999 (SL 9.6 Gen 2) is roughly in line with the category median (€4,350). The top build, SLR 9.9 XX Flight Attendant Gen 2, costs €13,999. Depending on the build, fork and shock come from FOX and RockShox. In total, 5 different forks are used, from the RockShox Reba RL to the RockShox SID SL Ultimate Flight Attendant.
Setup notes for this spec
- Fork (RockShox Reba RL): 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: 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.
- Shock (RockShox SIDLuxe (IsoStrut)): get on the bike in your normal riding position, step off carefully and read the O-ring. Always cycle the shock a few times after pumping.
Target SAG for the Trek Supercaliber
The table converts the recommended SAG percentages into millimetres, so you can check them with the O-ring directly on the stanchion and on the shock shaft. Adjust the air pressure until the value is right. If Trek specifies its own target SAG for your model, that takes priority.
110 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 19 mm |
| Trail | 20 % = 22 mm |
| Enduro / rough | 22 % = 24 mm |
| Bike park | 20 % = 22 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
The values apply to 2.40″ 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).
| 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.
