Shimano Di2 E-Tube Wires



  • Shimano Di2 E-Tube Wires use a fully removable individual cable system from the battery indicator junction box enabling fine tuning with the correct cable length to each component for easy and tidy fitments
  • EW-SD50 wires are required to connect the junction (either SM-JC40 external or SM-JC41 internal) to the rear mech, front mech, battery and to the handlebar battery indicator junction box
