Clean X3 Disc 32H rear Hub

Clean Trials X3 disc rear Hub

Clean X3 high-end rear disc hub. Now featuring a 12mm diameter through-axle, compatible with Cleans K1.2 20 carbon frame, available here.

Description and materials
- Clean X3 rear disc hub, developed specifically for bike trials by Spanish brand Clean.
- Tested and currently used by Clean Trials team riders Abel Mustieles and Dominik Oswald.
- Features a 12mm through-axle, specially designed for Clean’s K1.2 20” carbon frame.
- The 12mm axle is inserted from the side and bolted with an 8mm Allen key to the threaded inserts of the frame (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.
- 32 spoke holes (32H).
- Standard 6-bolt IS rotor mounts, neatly integrated into the hub’s shell to minimize torsion and ensure a much safer rotor fitting.
- Shimano HG splines, requiring a 4mm Lock Ring (included) to keep the sprocket in place.
- Sealed bearings ensure smooth spinning and prevent dust, mud and dirt from getting into the axle.
- Note: we recommend using this tool to fit the Lock Ring onto the hub.

Compatibility

- Bearings reference: 6902 2RS (disc side), 6802 2RS (non-disc side).
