How it compares
170 mm at the fork almost exactly matches the 170 mm median of the 56 bikes in the “e-enduro bike” category in our database. Front and rear both work with 170 mm of travel. Among Trek’s e-mountain bikes, the Trek Slash+ is the model with the most fork travel. Trek builds the frame from carbon.
At €6,999 for the 9.7 build, pricing is typical for the category (median €6,900). The top build, 9.9 X0 AXS T-Type, costs €10,499. Depending on the build, fork and shock come from FOX and RockShox. The fork line-up ranges from the FOX 38 Rhythm to the RockShox ZEB Ultimate. It is powered by TQ HPR60.
Setup notes for this spec
- Fork (FOX 38 Rhythm): 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.
- Air shock (FOX Float X Performance): measure SAG in your riding position, ideally with a helper holding the bike. Cycle the shock a few times after every pressure change.
- e-MTB: the extra weight mainly affects tyre pressure, which is why the table below already includes a surcharge. SAG is measured just as on a bike without a motor.
Target SAG for the Trek Slash+
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.
170 mm fork (all builds)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 29 mm |
| Trail | 20 % = 34 mm |
| Enduro / rough | 22 % = 37 mm |
| Bike park | 20 % = 34 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
Basis: 2.60″ tyre width, tubeless, trail casing, including the e-MTB surcharge. 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.
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.40 bar (20 psi) | 1.60 bar (23 psi) |
| 70 kg | 1.52 bar (22 psi) | 1.72 bar (25 psi) |
| 80 kg | 1.64 bar (24 psi) | 1.84 bar (27 psi) |
| 90 kg | 1.76 bar (26 psi) | 1.96 bar (28 psi) |
| 100 kg | 1.88 bar (27 psi) | 2.08 bar (30 psi) |
| 110 kg | 2.00 bar (29 psi) | 2.20 bar (32 psi) |
| 120 kg | 2.12 bar (31 psi) | 2.32 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.
