Shimano EW-SD300-I Di2 Wire -1000mm

Shimano SD300

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-I wire is suitable for STePS and Di2 components with SD300 connection type and designed for internal 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.
