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.
