Our advice

Shimano's 12-speed road generation requires a new wired connection from the battery to power the derailleurs. The standard is therefore becoming SD300.

Denis M.

A former racer with a keen eye for equipment

Optimise the connectivity of your electronic drivetrain with the Shimano Di2 E-Tube EW-SD300 cable, designed for the latest generation of 12-speed road groupsets. This cable transmits data and power between the various Di2 components (derailleurs, battery, shifters), ensuring smooth and ultra-precise operation.

Thanks to its slimmer and more compact design compared to the previous generation (EW-SD50), it facilitates internal routing within modern frames and enhances the bike’s overall aesthetics. Its reduced diameter (approximately 2.4 mm) allows for a more discreet routing whilst maintaining excellent reliability.

Available in several lengths (from 150 mm to approximately 1,600 mm), it adapts to all configurations, whether connecting the internal battery to the rear derailleur or linking the various cockpit components.

We advise you to err on the side of caution when calculating the length – you can never have too much...

Very good but maybe a bit expensive for a cable

The EW-SD300 is slimmer, lighter and compatible only with 12-speed Di2 groupsets. The connectors are different and not interchangeable.

No, older groupsets use the EW-SD50 standard.

This depends on the bike’s configuration (frame, internal/external cable routing). It is advisable to take precise measurements or to follow the manufacturer’s recommendations.

Yes, but we recommend using the TL-EW300 tool from Shimano to avoid damaging the connectors.
