Shimano XTR M9250 Di2 Rear Derailleur – Wireless, Durable, Made to Race
(Available in GS – Mid Cage or SGS – Long Cage)
Shimano’s XTR M9250 Di2 rear derailleur sets the standard for wireless mountain bike shifting. With ultra-fast, precise electronic performance, built-in impact protection, and a rugged low-profile design, it’s the perfect blend of race-day speed and real-world toughness.
Whether you're building a lightweight XC weapon or a big-hit enduro machine, there’s a version to match your setup:
🔧 Which One Do You Need?
-
GS – Mid Cage: Best for compact drivetrains (e.g. 9–45T cassette). Lighter and with better ground clearance – ideal for XC, trail, and enduro riders focused on efficiency.
-
SGS – Long Cage: Designed for wide-range drivetrains (e.g. 10–51T cassette). Perfect for all-mountain and enduro setups needing full-range 1x gearing.
Key Features (Both Versions)
-
Precise Wireless Di2 Shifting
Instant, smooth, cable-free shifts with Di2 + HYPERGLIDE+ tech. -
SHIMANO SHADOW ES Design
Low-profile, wedge-shaped body shrugs off rock strikes and glances off trail hazards. -
Automatic Impact Recovery
Gets knocked? No problem. The derailleur resets itself instantly after a hit. -
Reinforced & Silent
Wide-link structure, carbon cage, and solid pulleys make this the most durable XTR derailleur to date—with no rattles. -
Hidden Battery
Fully enclosed and protected, but easy to remove for charging.



Robust, Resilient, Ready for Anything
The centerpiece of this bomb-proof system is the new XTR M9250 rear derailleur, which features a unique low-profile wedge-shaped design that helps it avoid blunt force trauma—like when you cut a high-speed corner just a tad too tight while trying to shave seconds off your enduro race run. And even when the inevitable miscalculation does happen and you bang your derailleur into a sleeper rock, its unique shape and surface materials help it glance off, preventing catastrophic damage. The new derailleur also boasts a wide link structure, tough carbon skid-plate, and solid pulley design that reduces the chances of debris getting jammed inside.
