Shimano XT Di2 M8250 Upgrade Kit 2026

Shimano Deore XT Di2 – The new benchmark for MTB drivetrains: smart, rugged, and precise

The Shimano Deore XT Di2 represents the perfect balance of technology, reliability, and performance. Designed for demanding riders, this 12-speed wireless groupset delivers ultra-fast, effortless shifting even in the harshest conditions. With a 500% gear range, it's ready for everything from trail riding to all-mountain adventures.

The SHADOW ES rear derailleur introduces a new generation of stability with a more compact and robust design than its Shadow+ predecessor. It features an automatic recovery function: in the event of an impact, it instantly returns to its original position, extending its lifespan. Its oversized parallelogram body, reinforced pulleys, and armored cage deliver extreme durability and smooth shifting even in the dirtiest terrain.

The shifter excels with advanced ergonomics: familiar positioning, multi-axis adjustment, short-throw paddles, two-step shifting or continuous multi-shift—every move is intuitive and ultra-precise. Its compact design includes non-slip rubber paddles and a clamp or I-SPEC EV mount for a clean cockpit. Fully customize the controls via the E-TUBE PROJECT app, including the programmable third button.

The integrated 305 mAh battery is safely enclosed, remains stable even on rough trails, and is easy to remove for charging. It offers long autonomy and is recharged via the new, simple Di2 charger.

Shimano Deore XT Di2 – Wireless performance, bulletproof durability, and exceptional ergonomics. Built for riders who demand a responsive, intuitive, and uncompromising drivetrain.
