| Build | Fork | Weight | RRP | Calculator |

How it compares
100–110 mm at the fork almost exactly matches the 100 mm median of the 46 bikes in the “cross-country hardtail” category in our database. Among BMC’s mountain bikes, the BMC Twostroke 01 has the shortest fork travel. The frame is made of carbon.
9.9 kg for the One build puts the BMC Twostroke 01 mid-pack on weight (median: 10.0 kg). Up front, all builds get a RockShox fork. The fork line-up ranges from the RockShox SID SL Select 3P to the RockShox Judy Silver TurnKey. Worth knowing for heavier riders: the maximum system weight is 110 kg – after about 10 kg of bike, that leaves around 100 kg including kit.
Setup notes for this spec
- Fork (RockShox SID SL Select 3P): 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 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 BMC Twostroke 01
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 BMC specifies its own target SAG for your model, that takes priority.
110 mm fork (One)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 19 mm |
| Trail | 20 % = 22 mm |
| Enduro / rough | 22 % = 24 mm |
| Bike park | 20 % = 22 mm |
100 mm fork (Two)
| Riding style | Fork SAG |
|---|---|
| XC / touring | 17 % = 17 mm |
| Trail | 20 % = 20 mm |
| Enduro / rough | 22 % = 22 mm |
| Bike park | 20 % = 20 mm |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
Basis: 2.40″ 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: Vittoria Mezcal | XCR Casing | Tubeless | 2.35"; Vittoria Mezcal | XCR Casing | Tubeless | 2.4".
| 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.
