How it compares
100 mm at the fork almost exactly matches the 100 mm median of the 10 bikes in the “dirt jump bike” category in our database. Of CUBE’s mountain bikes, the CUBE Flying Circus offers the least travel up front. The frame is made of aluminium.
CUBE gives a weight of 12.6 kg for the Flying Circus build. Every build uses a RST fork.
Setup notes for this spec
- 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 CUBE Flying Circus
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 CUBE 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.

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.
