Shimano Deore XT M8250 Di2 Upgrade SW-M8250 Band-On BT-DN320 EC-DN100 SM-CN910 SGS Mech

Upgrade your mountain bike with the Shimano Deore XT M8250 Di2 Band-On Upgrade Kit, delivering the next generation of wireless electronic shifting. Designed for MTB riders who demand precision, durability, and seamless performance, this complete kit includes the XT Shadow ES 12-speed wireless rear derailleur (SGS cage, 10-51T compatible), SW-M8250 Band-On shifter, BT-DN320 battery, EC-DN100 charger, and SM-CN910 quick link.

The XT Shadow ES rear derailleur offers lightning-fast wireless shifting with a low-profile skid plate design and optimised slant angle for maximum ground clearance. Featuring a dual spring chain stabiliser, the derailleur reduces chain bounce on rough terrain for smoother, more stable power transfer. With a 70% increase in spring force, the tighter chain wrap prevents skipping and ensures perfect sprocket engagement even under heavy load or wear. The derailleur also features a crash recovery function that absorbs impacts and resets automatically, keeping you in the ride.

The SW-M8250 Band-On shifter is built for ergonomic comfort and efficiency, with 4-way multi-adjustable short-stroke paddles for responsive, effortless shifting. A rubber traction pad prevents mis-shifts, and riders can customise shifting preferences using Shimano E-Tube software. Options include multi-shift or single-shift modes, plus a third programmable button for trim adjustment, auto-shift mode changes, or D-Fly connectivity.

Powered by the BT-DN320 Li-Ion battery, this upgrade delivers reliable long-range performance with advanced power management. The EC-DN100 charger makes recharging simple and efficient, while the included SM-CN910 quick link ensures easy drivetrain integration.
