The Shimano EW-JC200 is a female-to-female, 2-port inline junction for compatible Di2 and E-TUBE wiring. Use it to connect two wires together as a Junction [B] connection point, helping you create a clean, practical wiring layout inside the frame.
This is a useful workshop component when an existing wire run needs extending, or when a build has additional shifters, a Y-connector or limited routing options. The junction can add 30 mm of wiring length and weighs just 5 g, so it solves routing problems without adding meaningful bulk.
The EW-JC200 connects directly with EW-SD50 wires. Shimano SD300 wiring can be connected to an SD50-port unit when used with the EW-AD305 adapter. Check your complete Di2 setup and wire standard before ordering; this is a wiring junction, not a wireless unit or electronic control component.
A practical choice for anyone repairing, extending or tidying a compatible Shimano Di2 or E-TUBE wiring system, particularly on internally routed or more complex builds.
Two-port inline junction
Join two compatible E-TUBE wires in a straightforward, tidy connection point.
Junction [B] function
Use it as a Junction [B] connection within compatible Shimano Di2 systems.
Extends wire runs
Adds 30 mm when extra length is needed for a larger frame or a tricky routing setup.
EW-SD50 compatible
Designed for Shimano EW-SD50 electric wires used in compatible E-TUBE systems.
SD300 system flexibility
Connects EW-SD300 wiring to an SD50-port unit when paired with the EW-AD305 adapter.
Internal routing support
A compact inline format helps keep wiring organised inside the frame.
Low weight
At 5 g, it adds very little to the overall system.
