Shimano XTR M9250 Di2 Upgrade Kit I-SPEC EV - Black

Shimano XTR Di2 — wireless, precise, and relentlessly robust. Built on over 27 years of XTR race technology, the latest Di2 platform delivers ultra-fast electronic shifting, rock-solid durability, intuitive ergonomics, and deep customization so you can focus on speed and line choice. The RD-M9250 Di2 rear derailleur introduces SHIMANO SHADOW ES: a low, wedge-shaped profile that glides past rocks and roots, a slim integrated chain stabilizer for silent control, and automatic impact recovery that snaps the derailleur back to position after a hit. A wide-link architecture, carbon cage plate, skid-plate protection, and solid pulleys enhance stiffness and longevity, while the sealed, removable battery is protected inside the body. Paired with the SW-M9250-R Di2 shifter, you get precise wireless shifts with tactile feedback, multi-shift options, four-way paddle adjustment, and a programmable third button—so you can control features like FREE SHIFT and AUTO SHIFT via the E-TUBE app and customize your cockpit exactly the way you like it.
