This is the correct plug-and-play wire for Shimano's E-Tube Di2 electric-shifting systems. It comes in sixteen different lengths, so choose the one(s) that's right for your Di2 E-Tube wiring configuration.

Shimano's Dura-Ace Di2 takes shifting to the next level. The Rear Wiring Kit connects to both the left and right shifters and Junction Box A (which displays battery power and allows manual adjusting). It also includes a battery mount, cable covers to route and hide the cables and a wire plug/unplug tool. The External Kit is meant to be run on the outside of the frame.
