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.

Simple and Durable

    Easy to use, snap in place securely, and durable.

    They make things move

    • Familiarity: I've put it through the wringer

    It's easy to install and it makes sure your derailleur shifts when you want it to.

    What you need

      This is the wire you need to install your Di2 group. It's a critical component of one of the best gruppos ever made.

      Straight Forward

      • Familiarity: I've put it through the wringer

      Shimano's e-tube wires work flawlessly. After a few Di2 set ups over the past couple years I have had zero issues.

      Durable wire!!

      • Familiarity: I've put it through the wringer

      It's the only wire you can get for connecting di2 components, but the quality is there, great and very durable.

      Shimano E-Tube Di2 Wire

      • Familiarity: I've put it through the wringer

      shockingly durable little wire that connects your components

      A little long for the D-Fly

      • Familiarity: I've used it once or twice and have initial impressions

      Purchased this to connect the D-Fly until to the rear derailleur. it is a little long. It would be great if CC stocked the 250 mm or 200 mm lengths

      they have 250, but not 200mm - bummer!

      E-Z does it.

        Electronic shifting...it's a thing of beauty! You'll need a few of these to complete any Di2 setup. If you have any questions on what you need, please give our customer service "Gearhead" team a call!

        no issues

        • Familiarity: I've put it through the wringer

        connections seem very secure and fits great inside my bike. I would certainly purchase this item again!

        About as easy as it gets

        • Familiarity: I've put it through the wringer

        Even though the E-Tube wiring has been around for a while, I still hear fears of use and concerns about durability. I've had the good fortune to build, test and unfortunately crash E-Tube equipped bikes for a couple years now and between the ease of setup and surprising durability of the system, I'm constantly impressed by how well it works. Wireless is the future, but until then we're in good hands!

        Unanswered Question

        Does it come with the wire holder? How many with each wire?

        Unanswered Question

        What is the length of The front wire harness ?

        any link to the product?

        Thanks

        etube di2 wire

        • Familiarity: I've used it several times

        i am amazed how robust this wire is and how well it fits neatly inside the frame. i was kind of hesitant about electrical wire on a road bike. but shimano did a great job of building very robust protective shield around the major wires for protection. it is not easy to cut one of these wire's unless you deliberately set out to do just that. Good product and it looks like it will last a long time.
