Shimano EW-SD300 E-Tube Electric Wire
The Shimano EW-SD300 is the current-generation E-Tube wire that carries power and shift signals between Di2 components, available here in lengths from 500mm up. Choose the length that suits your frame's routing when building, repairing or reconfiguring a Di2 drivetrain — it's the thinner standard used by 12-speed Di2 and current Shimano STEPS e-bike systems.
