Di2 Junction
Shimano Di2 EW-JC302 SD300 2-Port Junction
An inline connector that joins two EW-SD300 wires end to end inside the frame. Handy for extending a run or making routing easier on 12-speed Di2 builds.
Highlights
Why we rate it
Join two wires
Links a pair of EW-SD300 wires so you can extend a run or split a long routing into easier sections.
Sits inside the tube
Slim enough to live inside the frame tubing where it is out of sight and protected.
Sealed connectors
The water-resistant SD300 plugs keep rain and road spray away from the contacts.
Fits all 12-speed Di2
Shares the SD300 standard used by Dura-Ace, Ultegra, 105 Di2 and GRX Di2 12-speed.
