Deore XT M8250 Di2 Drivetrain Upgrade Kit

What Our Gearhead® Experts Are Saying:

"This kit is everything Shimano does best—wireless tech, bulletproof construction, and smart features like automatic impact reset. I paired it with a 10–51T cassette and it’s buttery smooth on every shift. A huge performance boost for anyone who wants to ditch cables without losing durability."

Shimano’s DEORE XT M8250 Di2 Drivetrain Upgrade Kit packages advanced wireless performance into a ready-to-install system, giving trail and enduro riders precision shifting, smarter derailleur protection, and clean, cable-free aesthetics. Whether you're chasing race lines or dialing in your all-day rig, this upgrade kit transforms your drivetrain with cutting-edge Di2 technology.

At the core is the M8250 Di2 rear derailleur—offered in mid- or long-cage lengths—featuring Automatic Impact Recovery to return the derailleur to position after rock strikes. A wide 500% gear range accommodates the full spread of Shimano’s 12-speed cassettes. The ergonomic RAPID ES shifter switch provides customizable, ultra-fast wireless shifts with tactile feedback, and connects easily via Shimano’s E-TUBE app for system tuning.

Power is delivered by the BT-DN320 battery, safely housed inside the derailleur for protection while staying removable for charging. Paired with the EC-EN100 charger and all required components, this kit is ready to upgrade your drivetrain from mechanical to intelligent, wireless efficiency—without changing your entire build.
