Shimano Spares XTR Di2 RDM9250 12-speed Rr. Der. w/ Med. Cage in Black

Brand:Shimano Spares

Code:Y3K79804T

Optimized for impact survivability, the 12-speed mid-cage M9250 rear derailleur is the choice for both Shimano's top enduro athletes and weight-conscious XC racers alike.

This derailleur is especially effective when matched with the 9-45 compact cassette. Featuring all-new wireless Di2 shifting, Automatic Impact Recovery, a redesigned wedge shape, and 23 mm of additional ground clearance for a bash-free ride, this rear derailleur stands out for the speed of its shift and its ability to keep riders competitive on the trail.

The new wedge shape of Shimano's most survivable rear derailleur to-date avoids more direct impacts and smoothly glances off rocks if there is a hit. The battery is tucked safely inside an enclosed space, ensuring it will not budge even in rough terrain, while remaining completely removable for charging.

Features:

  • Robust Design: A wide link structure, skid-plate design, durable carbon plate, and solid pulley add robustness and longevity.
  • RD Protection Function: The new Automatic Impact Recovery function instantly returns the derailleur to its original position after impact.
  • SHIMANO SHADOW ES: A slimmer, stronger evolution of Shimano’s pioneering chain-stabilizing SHADOW concept.
  • Precise & Clean Wireless Shifting: Wireless Di2 paired with HYPERGLIDE+ technology results in smooth, precise, and instantaneous shifting.
