How it compares
Up front the Trek Procaliber runs 120 mm – 20 mm more than the 100 mm median we calculated from 46 bikes in the “cross-country hardtail” category. Within Trek’s mountain bikes, it sits between the Trek Supercaliber and the Trek Top Fuel on travel. Depending on the build, the frame is aluminium or carbon.
Prices for the Trek Procaliber start at €1,199 (6), below the category median of €1,450. For the 9.7 Gen 3 build, Trek asks €3,999. Up front, all builds get a RockShox fork. In total, 5 different forks are used, from the RockShox Judy Silver to the RockShox SID.
Setup notes for this spec
- Air fork (RockShox Judy Silver): 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 RockShox suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
- Hardtail: only the fork needs setting up. With no rear suspension, rear tyre pressure is the key adjustment for comfort and grip.
Target SAG for the Trek Procaliber
The table converts the recommended SAG percentages into millimetres, so you can check them with the O-ring directly on the stanchion. Adjust the air pressure until the value is right. If Trek specifies its own target SAG for your model, that takes priority.
120 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 20 mm |
| Trail | 20 % = 24 mm |
| Enduro / rough | 22 % = 26 mm |
| Bike park | 20 % = 24 mm |
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.
| 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
You will find a guide value for air pressure on the fork sticker or in the suspension makers’ charts. Our calculator also takes riding style and rebound into account. In the end, measured SAG is what counts.
