Description
The JC200 connector is a small junction box that helps connect the electronic wires in Shimano’s E-Tube system.
E-Tube is the wiring system that carries signals between your bike’s electronic shifting parts. Like the shifters, derailleurs, and battery.
This connector has two ports. Which means it can connect two E-TUBE wires together in a straight line.
Think of it like an extension cord that lets you join two shorter wires to make one longer connection.
What does it do?
Connects E-Tube wires when you need to extend or split your electronic shifting system
Keeps wires organised and secure inside your bike frame
Allows mechanics to easily disconnect parts for maintenance or upgrades
Why you might need it
If you’re building a custom bike setup, replacing parts, or need to route wires through your bike frame in a specific way, this connector helps make clean, reliable connections.
