Product details

The upgrade kit from Shimano allows you to convert an existing mechanical 1x12-speed Shimano drivetrain to an electronic Di2 system. This set includes the RD-M9250-GS rear derailleur, the SW-M9250-IR shifter, the BT-DN320 battery and the matching EC-DN100 charger. An SM-CN910-12 chain lock is also included, which makes the system easier to install and use.
