Shimano EW-JC200 2-Port Di2 Junction Unit


The EW-JC200 2 port junction is a female-female junction box that allows wires to be connected together to increase their length. This gives you greater flexibility when running wiring on larger frames or in tricky wiring cases with additional shifter. For use with Di2 and E-Tube wiring.


Please Note:- E-tube is a two prong system and is NOT cross compatible with older Dura-Ace 7970 Di2 wiring.
