Sturmey Archer Crank Guide HSA123

This Sturmey Archer crank guide is the internal “driver” component that transfers your pedaling force to the hub shell in classic Sturmey Archer 3-speed drum and gear hubs. Sitting between the axle and sprocket, it engages the hub’s planetary mechanism so the wheel turns smoothly in every gear. Replacing a worn or damaged crank guide restores clean drive engagement, reduces play and noise, and helps keep older city or touring bikes with Sturmey Archer hubs running reliably for many more kilometers.

- Crank guide / driver for Sturmey Archer internal gear hubs
- Transmits pedal power from the sprocket into the hub’s planetary mechanism
- Suitable for use in various front and rear 3-speed Sturmey Archer drum and gear hubs

- Genuine Sturmey Archer part for correct fit and long-term durability
