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.

Need a spare Shimano cable adjuster assembly for your Dura-Ace R9100 rear derailleur? You've found it. Making sure this part is in working order can mean the difference between a two-second barrel twist to return your shifting to perfect, or getting out the multi-tool to readjust the cable again and again until it's close enough to get home. Your choice.
