XTR RD-M9250-GS Di2 Wireless Rear Derailleur - 12-Speed Medium Cage Shadow ES

Engineered for elite XC racers and enduro athletes alike, the Shimano XTR RD-M9250-GS rear derailleur delivers lightning-fast wireless Di2 shifting and unmatched trail survivability. Optimized for use with Shimanos 9-45T compact 12-speed cassette (sold separately), this medium cage derailleur strikes the perfect balance between speed, clearance, and durability.

Thanks to HYPERGLIDE and wireless Di2 integration, every shift is crisp, smooth, and immediate. The Shadow ES design reduces the derailleurs frontal profile while a new wedge-shaped form glances off obstacles, adding 23mm of ground clearance for rock-dodging confidence. Meanwhile, Automatic Impact Recovery ensures the derailleur realigns instantly after a hit keeping you focused on the trail, not your drivetrain.

Key Features:

• Wireless Di2 shifting with HYPERGLIDE for ultra-fast, precise gear changes
• 510% gear range when paired with Shimanos 9-45T cassette
• Automatic Impact Recovery function instantly realigns after impacts
• Shadow ES low-profile design minimizes snags and damage
• Carbon outer plate, wide link structure, and skid-plate for lightweight durability
• Enclosed battery is secure in rugged terrain but easily removable for charging
• Medium cage ideal for compact 12-speed setups with aggressive gearing

This is Shimanos most advanced and impact-resilient derailleur yet perfect for competitive riders who need flawless function when it matters most.
