Genuine Shimano EW-SD300 Di2 E-Tube electric wire, 1400mm, for external routing. This is the second-generation Di2 wire used to carry power and shift data between Di2 components and the battery, with a slimmer 2.1mm cable and 3.2mm plug than the older EW-SD50 standard. The connectors are moulded to the wire and cannot be cut or shortened.

  • To connect to older EW-SD50 (11-speed) Di2 components, the EW-AD305 adapter is required
