XTR Di2 Rear Derailleur delivers rugged, wireless shifting precision for 12-speed trail setups
What Our Gearhead® Experts Are Saying:
"The XTR Di2 long-cage derailleur is a total game-changer. Wireless shifting is crisp and immediate, and it’s built tough—like, really tough. I’ve clipped it on rocks and watched it bounce back without missing a beat. Add in crash recovery and a clean look? It’s the future of trail drivetrains."
When we’re riding full-speed through aggressive trails, we need a derailleur that can shift with precision and survive the terrain. The Shimano XTR RD-M9250-SGS Rear Derailleur takes everything we know and love about XTR and pushes it further with wireless Di2 shifting, all-terrain durability, and smart, self-correcting recovery tech. Built to pair with Shimano's 10-51T 12-speed cassettes, this long-cage derailleur delivers both wide-range gearing and ultra-fast response.
With features like Automatic Crash Recovery and a new wedge-shaped body that glances off impacts, the M9250 is built to take hits and keep going. The SHADOW ES profile keeps the derailleur tucked and quiet, while Hyperglide+ technology ensures ultra-smooth shifts—even under load. From enduro stages to backcountry lines, this is Shimano’s toughest, most advanced rear derailleur to date.
