How it compares
On travel, the Transition PBJ is right where the “dirt jump bike” category usually is: 100 mm up front against a median of 100 mm from 10 bikes. Of Transition’s mountain bikes, the Transition PBJ offers the least travel up front. Transition builds the frame from aluminium.
The Transition PBJ is not a budget bike: even the PBJ build costs €2,199, while the category median is €1,700. Every build uses a Marzocchi fork.
Setup notes for this spec
- Fork (Marzocchi Bomber DJ): 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 Marzocchi 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 Transition PBJ
SAG is the share of travel your weight already uses in the riding position. The table gives it straight in millimetres – read the O-ring on the stanchion and adjust the air pressure until it matches. Any figures from Transition take priority.
100 mm fork (all builds)
| 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
The values apply to 2.25″ 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). Stock tyres: Schwalbe Billy Bonkers (2.25) / Schwalbe Billy Bonkers (2.25).
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.53 bar (22 psi) | 1.73 bar (25 psi) |
| 70 kg | 1.65 bar (24 psi) | 1.85 bar (27 psi) |
| 80 kg | 1.77 bar (26 psi) | 1.97 bar (29 psi) |
| 90 kg | 1.89 bar (27 psi) | 2.09 bar (30 psi) |
| 100 kg | 2.01 bar (29 psi) | 2.21 bar (32 psi) |
| 110 kg | 2.13 bar (31 psi) | 2.33 bar (34 psi) |
| 120 kg | 2.25 bar (33 psi) | 2.45 bar (36 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.
