Shimano Deore XT M8250 Di2 Shadow 12-speed medium cage derailleur

The Shimano Deore XT M8250 Di2 Shadow 12-speed medium cage derailleur incorporates the brand-new wireless Di2 shifting technology and an automatic impact recovery function, which immediately returns the derailleur motor to its original position after an impact. What doesn't get hit doesn't break: the new XT rear derailleur's flat wedge-shaped design avoids most impacts on the trail. And if an impact occurs, the rear derailleur can slide away from trail obstacles 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, sliding plate design, and robust derailleur pulleys ensure sturdiness and durability.
