SHIMANO | EW-SD300 Di2 Wire - E-Tube System (2nd Gen.) - external cable routing

Introduced with the Shimano EP800 series, the SD300 E-Tube components form the interface between compatible STePS parts and expand the functional range of future Di2 systems.

The electronic Shimano EW-SD300 wire is suitable for STePS and Di2 components with SD300 connection type and designed for external cable routing.

A more compact design makes the SD3000 components smaller and lighter, that is why the EW-SD300 cables are sleeker than the previous EW-SD50 version.

Diameters: 2.4 mm (cord) / 3.45 mm (plug)
