The Shimano XT Di2 M8250 Drivetrain Upgrade Kit is designed for mountain bikers looking to upgrade their existing 12-speed Shimano MTB drivetrain to the next level of performance with electronic, wireless shifting.

This kit brings the ultra-fast, precise, and customizable shifting performance of Di2 (Digital Integrated Intelligence) to the Deore XT level, benefiting from trickle-down technology from the top-tier XTR Di2 system.

 

📦 What's Included in the Kit:

 

The core M8250 upgrade kit typically includes the essential electronic components to transition your mechanical 12-speed system to Di2:

• Rear Derailleur: Shimano XT Di2 RD-M8250-SGS (Long-cage, 12-speed). This is the "brain" of the system, optimized for impact survivability and offering the consistent, quick shifts Di2 is known for.

• Wireless Shifter: Shimano XT Di2 SW-M8250 (usually I-Spec EV mount) - This communicates wirelessly with the rear derailleur. It provides intuitive, customizable controls for instant shifting.

• Battery: Shimano BT-DN320 - The internal battery that powers the system.

• Charger: Shimano EC-DN100 - Used to charge the internal battery.

• Chain Quick-Link: A quick-link for an SM-CN910 chain (you may need a new chain depending on the wear of your existing one, though the quick-link is included for a new chain installation).
