## Overview

The Shimano BMDN100 Di2 Long Battery Mount enables existing Shimano Di2 users to wirelessly upgrade their external wiring setups. Compatible with SM-BTR1 batteries, it supports Bluetooth and ANT+ connectivity for seamless mid-ride shifting adjustments via the E-Tube Wireless app. Lightweight and durable, this mount comes with a 2-year warranty, making it the perfect accessory for professional and enthusiast cyclists seeking smarter, more connected rides.

## Description

Somehow, Di2 can't help but keep getting smarter. With a new Bluetooth battery and Shimano's E-Tube Wireless app, you can now change your shifting preferences wirelessly in the middle of a ride with a smartphone or ANT+ head unit. New versions of Deore XT Di2 will ship with this compatibility built-in, but Shimano created the BM-DN100 Di2 Battery Mount to allow current Di2 users to adapt their earlier generation Di2 drivetrains to work wirelessly as well. If you have your drivetrain set up externally, you'll need this mount, as well as a compatible wireless unit or display to go wireless.
