FAQ

What is the EW-JC200 used for?: The EW-JC200 is a 2-port junction that links E-Tube wires together, allowing branching or extension of the Di2 wiring harness. It is essential for builds where the wiring path requires a junction point.

Is this junction compatible with both EW-SD50 and EW-SD300 wires?: Yes. The EW-JC200 works with Shimano EW-SD50 and EW-SD300 E-Tube wires across all Di2 generations.

Why only 2 ports?: Two ports are designed to connect two E-Tube wires together. For more complex builds requiring three or four ports, dedicated multi-port junctions or junction boxes are available.
