Electric Wire / e-Tube cable

EW-SD300 - Electric Wire / e-Tube cable image

The next-generation Shimano EW-SD300 electric wire is used to connect the individual parts of the EP8 E-MTB and future Di2 series to each other. They're available in a lot of different sizes:

  • 150mm
  • 250mm
  • 300mm
  • 350mm
  • 400mm
  • 500mm
  • 550mm
  • 600mm
  • 650mm
  • 700mm
  • 950mm
  • 1000mm
  • 1200mm
  • 1400mm
  • 1600mm

These wires are smaller than the older EW-SD50. The wire diameter is about 2.1mm and the plug itself is 3.2mm.

Despite the obvious differences in size between the EW-SD50 and the EW-SD300, they're both E-Tubes. You can wire up any Di2 series using EW-SD300 wires, but you'll need the EW-AD305 adapter.

You cannot use the TL-EW02 tool to connect these wires, it is too big. The correct tool is the TL-EW300.
