Overview

A suitable choice for anyone repairing, extending or installing an externally routed E-TUBE Di2 setup that requires a 1400 mm SD50 wire.

The Shimano EW-SD50 Electric Wire is a 1400 mm E-TUBE Di2 connection cable for linking compatible electronic components. It carries interactive signals and power through the system, making it suitable for connections between junctions, derailleurs, batteries and compatible handlebar junction components.

With two SD50 connectors and a slim ø2.8 mm cable, it is designed to keep an externally routed installation tidy. The compact ø5.1 mm plugs use a straightforward plug-and-gap connection, while the sealed connector design helps protect the connection in wet riding conditions.

Choose this wire when your Di2 setup needs a longer run and you have confirmed that your components use the SD50 connector standard. It is not a cut-to-length cable, so selecting the correct length before installation helps avoid excess cable and keeps routing clean. The 1,600 mm length in this range is intended for e-bike use only; this product is 1400 mm.
