How it compares
On travel, the Transition Spur is right where the “downcountry bike” category usually is: 130 mm up front against a median of 130 mm from 13 bikes. The rear offers 120 mm, 10 mm less than the front. On travel, it slots in between the Transition PBJ and the Transition Smuggler in the Transition range. Transition builds the frame from carbon.
The Transition Spur is not a budget bike: even the Eagle 70 build costs €5,999, while the category median is €5,000. For the XTR Di2 build, Transition asks €11,699. Fork and shock come from FOX on every build. The fork line-up ranges from the Fox Float 34 SL Performance to the Fox Float 34 SL Grip X Factory.
Setup notes for this spec
- Fork (Fox Float 34 SL Performance): 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 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 SL Performance): 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 Transition Spur
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 Transition specifies its own target SAG for your model, that takes priority.
130 mm fork, 45.0 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 22 mm | 24 % = 10.8 mm on the shock shaft |
| Trail | 20 % = 26 mm | 28 % = 12.6 mm on the shock shaft |
| Enduro / rough | 22 % = 29 mm | 30 % = 13.5 mm on the shock shaft |
| Bike park | 20 % = 26 mm | 27 % = 12.2 mm on the shock shaft |
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. Stock tyres: Maxxis Forekaster 3C EXO+ (2.4) / Maxxis Forekaster 3C EXO+ (2.4); Maxxis Forekaster EXO/TR (2.4) / Maxxis Forekaster EXO/TR (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 and shock
The sticker on the fork (or on the shock) and the manufacturers’ setup charts give you a first pressure. Our calculator is more precise and suggests rebound too – always check the result via SAG.
