Description

The SHIMANO BT-DN300 internal battery is designed for Di2 12-speed electronic drivetrains compatible with SD300 connectivity. Retaining the same form factor as the previous model, it fits discreetly inside the frame or seat post for a clean build and sleek aesthetics.

Equipped with 3 SD300 ports, it simplifies the wiring of the front and rear derailleurs while ensuring a stable power supply. Its third port also allows you to maintain a wired Di2 12-speed configuration as needed.

Compatible with new-generation SHIMANO systems from the R9250/R8150 series onwards, the BT-DN300 uses the same mounting method as the BT-DN110, making it easy to install and integrate on compatible bikes.
