The Shimano Deore Di2 Drivetrain Upgrade Kit makes it easy to convert to Deore M6250 wireless electronic shifting while keeping your existing 12-speed Shimano MTB drivetrain. Built for fast, precise shifts, and endless customizability, this system pairs an ergonomic Deore Di2 shifter with a robust RD-M6250 SGS rear derailleur that’s designed to handle trail impacts while maintaining consistent shifting. The derailleur houses the Di2 battery in a protected, enclosed compartment, and Shimano’s Automatic Impact Recovery helps return it to position after a hit. This kit includes the key components you need to get up and running—shifter, derailleur, battery, charger, and chain link—so you can swap parts, pair up, and ride.
