How it compares
On travel, the Rose Bruce is right where the “dirt jump bike” category usually is: 100 mm up front against a median of 100 mm from 10 bikes. Among Rose’s mountain bikes, the Rose Bruce has the shortest fork travel.
In total, 2 different forks are used, from the Manitou Circus Expert to the Marzocchi Bomber DJ 26.
Setup notes for this spec
- Air fork (Marzocchi Bomber DJ 26): 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: turn the red Marzocchi adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
- 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 Rose Bruce
Instead of percentages, this table gives SAG directly in millimetres, measurable with the O-ring on the stanchion. Change the pressure step by step until you reach the value; if Rose gives its own target SAG, use that.
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

Air pressure in the fork
The sticker on the fork 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.
