Shimano’s DEORE XT M8250 Di2 Rear Derailleurs redefine reliability and responsiveness for 12-speed trail systems, with both GS (mid-cage) and SGS (long-cage) variants tailored to different drivetrain setups. The GS version is optimized for compact 9-45T cassettes, providing significant weight savings, ultra-precise wireless Di2 shifting, and a 500% gear range in a tight, trail-ready package. Key features include Automatic Impact Recovery, which instantly re-aligns the derailleur after a knock, and a redesigned form with 23mm of added ground clearance to minimize impact risk. Built with a wide link structure, skid plate protection, and durable aluminum plates, the M8250 GS rear derailleur thrives in aggressive trail environments. Shimano’s SHADOW ES design enhances stability while maintaining a slim profile, and the integrated battery is safely enclosed but easily removable for charging.

The SGS long-cage version pairs seamlessly with the classic 10-51T M8200 cassette, offering expanded range for all-mountain and enduro riders. Despite its extended capacity, the M8250 SGS maintains rapid shift performance, even under load, thanks to Shimano’s refined Di2 electronics and mechanical architecture. A new wedge-shaped cage profile deflects impacts, while covered pulleys and shielded teeth keep mud and debris from interfering with drivetrain performance. Like the GS version, the SGS also features SHADOW ES chain management and the resilient Automatic Impact Recovery system. Whether you prefer a compact, lightweight build or a full-range drivetrain, the M8250 series delivers the rugged dependability, advanced protection, and flawless shifting performance that define DEORE XT.
