Bombproof dependability has gone electronic. Shimano's famed Alfine internally geared rear hubs have been a mainstay of urban bikes and those looking for a bike with plenty of gears to choose from that rarely need servicing. In its latest, and most revolutionary, update to this iconic piece of cycling gear, Shimano has made it ready for electronic shifting. The shifting is now easier and faster.

This internally geared hub is fully compatible with both Alfine 8-speed Di2 shifters, features a Centerlock disc brake mount, but is also V-brake compatible.

It requires the MU-S705B 8-speed motor unit, roto, axle nuts, cog snap-ring, non-tun washer, and optional CS-S500 sprocket. Requires Di2 control unit, wiring harness, battery and shifter to operate.

This is a hub only.

  • Di2 electronic compatibility for fast, precise, weather-proof shifting
