A practical replacement or installation wire for anyone servicing a compatible SD50 E-TUBE Di2 system and needing a 400 mm external-routing connection.
This 400 mm E-TUBE electric wire is designed for compatible Di2 systems using SD50 connections. It links electronic drivetrain components for signal transmission and power delivery, making it suitable for connections between a junction, derailleur, battery or handlebar battery indicator where the required run is 400 mm.
The slim 2.8 mm cable and 5.1 mm plugs help keep routing discreet, while the two-prong SD50 connectors provide a straightforward plug-in connection. The waterproof connector design helps protect the electrical connection in cycling conditions, and the black finish blends neatly with most frames and components.
Choose this wire when you need a dedicated external-routing connection and have confirmed that your system uses SD50 rather than another E-TUBE connection standard. The 400 mm length is supplied ready to fit; these individual wires are available in set lengths and are not intended to be cut.
