1st Gen E-Tube Di2 Wire

The Shimano 1st Gen E-Tube Di2 Wire plays an integral and important role in assembling your 6770, 6870, or 9070 Di2 group. Without it, you can't install your Di2 derailleurs, shifters, or battery. So, check the size chart on this page for length, and don’t worry about the rest. If you’re running Ultegra 6770 or 6870, or Dura-Ace 9070, this E-Tube Di2 Wire will connect up all the moving parts. Its connectors are the same, regardless of application, so all you have to do is choose the length that’s best suited.

  • Connector wires for Shimano's E-Tube Di2 system
  • Easily clicks into place for quick and easy install
  • May be used for internal or external applications

Di2 Reference Guide
Battery and Wires: Our Shimano Di2 packages are built for three standard configurations based on battery location and wire routing. First, you'll need to determine if your frame uses an internal or external battery mount, and whether the routing is either internal or external. Below is a guide for which battery, charger, mount, and junction boxes are required for your configuration.

Battery Mounts: The SM-BMR2 battery mount is available in three configurations -- Long External, Short External, and Long Internal. Both Long versions are to be mounted using the bottle cage mounts, while the Short version is designed for Di2-specific frames with either a chainstay or down tube mounting location.

Junctions: There are two junctions needed for completing your Di2 build -- A and B. Junction A, SM-EW90, is located at the handlebars and available in both three- and five-port options. The three-port option is intended for standard shifting with a left and right hand shifter. If you have the intention of using Shimano's satellite sprint shifters, or a combination of time trial shifters and shifter/brake levers, the five-port junction box will be the necessary selection.

Depending on your frame specification, Junction B (SM-JC40 or SM-JC41) is located either internally or externally at the bottom bracket area. Accordingly, SM-JC41 is designed for frames with internal wire routing, while SM-JC40 is intended for external wiring options.

E-Tube Wires: For your convenience, we've created wire packages for your Di2 build kit in the sizes Small, Medium, and Large. Below, you'll find which wire lengths are included in each kit. Additionally, we've recommended a kit size based on your frame size.
