Bring smooth, automatic electronic shifting to an internally geared commuter or urban e-bike with the Shimano Di2 MU-UR520 drive unit. It turns a NEXUS or ALFINE internal hub into a Di2 system, taking the guesswork out of gear changes so you can simply ride.

Highlights

  • Adds Di2 electronic shifting to NEXUS INTER-5E/8 and ALFINE INTER-11/8 internally geared hubs
  • AUTO SHIFT changes gear for you to keep a consistent, relaxed cadence
  • Works with both belt drive and chain drive systems
  • Wireless LED indicator and function button for clear, simple operation
  • Keeps the same belt/chain line clearance as the MU-UR510 for straightforward installation

Effortless, automatic shifting

With AUTO SHIFT, the system selects gears for you to hold a steady cadence, making cruising and stop-start city riding more enjoyable and less effortful. Manual electronic shifting is on hand whenever you want to take control.

Clean, low-maintenance drivetrains

Because it supports belt drive as well as chain, the MU-UR520 suits riders who want a quiet, low-maintenance setup. Matching the clearance of the previous MU-UR510 makes it an easy fit for compatible builds.
