Electric Wire / e-Tube cable

EW-SD50 - Electric Wire / e-Tube cable image

The Shimano EW-SD50 electric wire connects the individual parts of the Di2 system to each other. They're available in a bunch of different sizes. You'll need about 6 of them, depending on your specific setup and frame size. The generally available sizes are:

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

That 1600mm wire is meant to be used on E-Bikes only, but I haven't seen it fail on road bikes myself. If you're thinking of using this on a road bike - you probably can.

You can connect EW-SD50 wires to the next generation EW-SD300 E-Tube wires using the EW-AD305 adapter. This is good news, because that means you can use all of your older components with future Di2 series.
