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 added a few extra gears and made it ready for electronic shifting. The shifting is now easier and faster.

This internally geared hub is fully compatible with both Alfine 11-speed Di2 shifters and Di2 road shifters, features a Centerlock disc brake mount, but is also V-brake compatible.

Note: this is the hub only. It must be built up with a rim and compatible spokes. Shifting requires the MU-S705 11-speed motor unit (item # 50-2764) and optional CS-S500 sprocket. If using with Ultegra and Dura-Ace Di2, all components require the same firmware version to operate.

  • Di2 electronic compatibility for fast, precise, weather-proof shifting
  • 11-gear ratios available
  • Centerlock disc brake and v-brake compatible
  • 135mm bolt-on axle
