Product Information
Full details
The Shimano E-tube EW-JC130 is an essential component for cyclists running electronic shifting systems who need to route wiring to multiple points, such as integrated shifters and junction boxes. It is ideal for building a clean, streamlined cockpit, though users should ensure their specific frame and component setup matches the fixed cable lengths of 350mm, 50mm, and 450mm to avoid excess slack or tension during installation.

FAQs
Can I trim these cables to fit my bike better?
No. E-tube wires contain sensitive electronic conductors and must not be cut or modified.
Is this compatible with Shimano Di2 road and mountain systems?
It is compatible with any E-tube system that uses the EW-SD50 connector standard.
Does this cable require any firmware updates?
The cable itself is a passive connector and does not require firmware, but components connected to it may.
What tools do I need for installation?
You generally only need the TL-EW02 tool to safely connect or disconnect the wires.
Is this cable shielded against electromagnetic interference?
Yes, Shimano E-tube wires are designed to maintain signal integrity in demanding electronic environments.
Troubleshooting
Intermittent shifting or missed signals
Check that all three connectors are fully seated and clicked into their respective ports.
Cable seems too short or too long for frame
Verify your internal cable routing path; adjust the junction box placement to accommodate the 350/50/450mm lengths.
Difficulty removing the cable from a component
Do not pull the wire directly. Use the TL-EW02 removal tool to release the locking tab safely.
