Description

Just what you needed.

You'll see that the E-Tube Di2 SM-BMR1 Battery Mount is available in three options -- Long External, Long Internal, and Short. Both the long versions mount from one of the water bottle mounts on the down or seat tube of your frame. However, they're designed to be paired specifically with either type of wiring kit you'll be using -- Internal or External.

The short version is designed to be used on bike frames that bear a specific Di2 battery mounting location on the chainstay or down tube, separate from the water bottle mounts. It can be used with internal or external wiring kits.

The Shimano E-Tube Di2 SM-BMR1 Battery Mount accepts the SM-BTR1 7.4 volt battery. Please Note: This is only the mount (battery not included).

Di2 Reference Guide

 

Note: This reference is meant to be used as a guide for creating a Shimano Di2 drivetrain package. For further assistance please feel free to give us a call.

 

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.

Shimano integration

  • Familiarity: I've put it through the wringer

Bought this for a new frame and thankfully Shimano developed these mounts to be easily fitted from short mount to long mount. Works flawlessly!

Does this battery mount work with Dura ace...

Does this battery mount work with Dura ace 9070?

Responded on

Yes, this mount would work with Dura-Ace 9070. It would depend on your frameset and how you were planning on running the wires for your Di2 system whether or not this would be the mount that you would want.
