Shimano XTR RD-M9250-SGS 12-speed Di2 Rear Derailleur
Rugged, indestructible and ready for anything – The Shimano XTR RD-M9250-SGS 12-speed rear derailleur introduces the latest wireless Di2 shifting technology, designed for extreme MTB use. Its innovative automatic crash recovery function returns the derailleur motor to its original position immediately after impact, ensuring uninterrupted performance.
Low-profile wedge-shaped design prevents most trail collisions with rocks or obstacles. A smooth outer surface allows the derailleur to slide off obstacles instead of snagging, minimizing damage. In the event of a hit, the automatic recovery ensures the drivetrain remains functional.
Enhanced structure: wide linkage body, durable carbon plate, robust skid plate and solid pulleys ensure high rigidity and long-lasting durability. The SHIMANO SHADOW ES mechanism keeps chain tension consistent, reducing chain slap and preventing derailment even on rough terrain.
Wireless Di2 shifting combined with HYPERGLIDE+ offers crisp, precise and instantaneous shifting without mechanical cables. The intuitive control setup lets riders focus fully on the trail.
The battery is safely housed inside the frame and is fully removable for charging. A built-in LED status indicator shows system activity and helps with setup and diagnostics.
Shimano XTR – peak performance for pro racing: as Shimano's lightest and most advanced MTB component group, XTR is engineered for elite XC and Enduro competition. Rugged, responsive and ultra-reliable, it delivers confidence from the start line to the finish.
