The Shimano Upgrade Kit allows for the conversion of an existing mechanical 1x12-speed Shimano drivetrain to an electronic Di2 system. This set includes the RD-M9250-SGS derailleur, the SW-M9250-IR shifter, and the BT-DN320 battery, which is necessary for powering the derailleur. Additionally, a charger (EC-DN100) and a chain link (SM-CN910-12) are included to ensure a complete and smooth installation. The upgrade kit is specifically designed for use with a 12-speed cassette with a maximum sprocket size of 51 teeth, making it ideal for mountain bikes. With this kit, cyclists can take advantage of the benefits of electronic shifting technology, which offers precise shifting and improved performance.
