Battery Shimano Di2 BT-DN320 Built-In

Robust. Intuitive. Consistent. - is the motto for the new XTR M9250 groupset. With it, Shimano and the bike community are celebrating the rebirth of Di2 technology on their top model. And at the very highest level. Thanks to contemporary wireless control, perfect functionality, a 12-speed drivetrain and the usual outstanding build quality, you will be able to go from victory to victory and give the competition a run for their money.

A major innovation compared to the previous Di2 versions is the elimination of the central power supply. This means that cumbersome wiring is no longer necessary, which makes installation much easier. The small 305 mAh battery is plugged directly into the rear derailleur. There it sits invisibly, protected against loss and supplies it inconspicuously with the necessary energy. Despite the waterproof compartment, it can be removed quickly and easily for charging.
