E-tube Di2 uses 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 fitment. 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. There is no need (or facility) to cut these cables, which are reliable and secure with water resistant connectors.
