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

Shimano XTR Di2 — wireless, precise, and unbelievably robust. Born from elite MTB racing, XTR Di2 delivers ultra-fast, ultra-accurate electronic shifting with race-proof durability and intuitive ergonomics so you can focus on the line, not your levers. The RD-M9250 Di2 rear derailleur debuts SHIMANO SHADOW ES: a low, wedge-shaped profile that glides past trail strikes, a slim integrated stabilizer for silent chain control, and an automatic impact-recovery function that snaps the mech back to position after a hit. A wide-link architecture, carbon cage plate, skid-plate details, and solid pulleys round out a derailleur built to convert every watt into forward speed—lap after lap, stage after stage.
