Clean X3 Disc 28H front Hub

Clean X3 Disc 28H front Hub

Description and materials
- Clean X3 front disc hub, developed specifically for bike trials by Spanish brand Clean.
- Tested by Clean Trials team riders Abel Mustieles and Dominik Oswald.
- Features a 12mm through-axle, specially designed for Clean K1.2 20” carbon fork.
- The 12mm axle is inserted from the side and bolted with an 8mm Allen key to the threaded inserts of the fork (available here).
- Both the axle and shell are CNC 3D machined from high quality 7075-T6 aluminium alloy, which ensures extraordinary mechanical properties.
- Tapered shell profile helps save weight thanks to the smaller size of the non-disc side flange.
- The hub flanges have machined edges between the spoke holes, removing unnecessary weight without reducing strength.
- 28 spoke holes (28H).
- Standard 6-bolt IS rotor mounts, neatly integrated into the hub’s shell to minimize torsion and ensure a much safer rotor fitting.
- Sealed bearings ensure smooth spinning and prevent dust, mud and dirt from getting into the axle.

Compatibility
- Forks designed for a 12mm thru-axle with 104mm spacing, like Clean’s K1.2 20” carbon fork (requires these inserts).
- Rims with 28 spoke holes (28H).
- Rotors with 6-bolt IS mounts.
- Bearings reference: 6902 2RS (disc side), 6802 2RS (non-disc side).
