Shimano E-Tube Di2 Short Battery Mount BM-DN100
If you have an external wired set-up and want to change your older Shimano Di2 drivetrain to a Bluetooth wireless interface, you will need a few items. First, you need a Di2 SM-BTR1 battery. Second, you need a mount, which has the interface the battery plugs into. If you require a short version (based on distance and clearance) that mounts at water bottle cage bosses, then this E-Tube Di2 Short Battery Mount BM-DN100 is the correct part. The last piece you need is a Bluetooth Smart compatible interface, as in a Di2 E-Tube EW-WU101 or EW-WU111 receiver.
If you need this Shimano E-Tube Di2 Short Battery Mount BM-DN100 for your set-up, you should know that the unit has one E-Tube port, which allows for battery updates with the E-Tube Project wireless app through a receiver option. With the proper set-up you can also adjust shifter function in the same manner.
