Shimano XT Di2 RD-M8250 12-speed Rear Derailleur

Robust, indestructible and ready for anything.

Robust, intuitive and consistent: XT Di2 RD-M8250 12-speed Rear Derailleur from Shimano

What doesn't get hit can't get broken - the flat, wedge-shaped design of the new XT rear derailleur prevents most stone chips and impacts on the trail. And if an impact does occur, the rear derailleur can slide off obstacles on the trail thanks to the smooth outer coating, preventing catastrophic damage. The automatic impact recovery function immediately returns the derailleur motor to its original position after an impact, while the wide joint structure, durable plate, skid plate design and solid derailleur pulleys ensure robustness and durability.

From the foundational moments in the early 1980s when DEORE XT first revolutionized mountain biking, SHIMANO brings fast and reliable shifting, a robust drivetrain construction, and refined braking systems to more riders with the latest introduction of DEORE XT M8200 Di2 components. Following the recent launch of our flagship XTR M9200 race group, DEORE XT receives key technology and design cues from XTR, delivering a robust group designed to withstand the demands of real-world riding, and consistently redefining what's possible on two wheels.
