Rear derailleur XTR RD-M9250

The Shimano Di2 XTR M9250 wireless long-cage derailleur, combined with a standard 10-51 tooth M9200 cassette (cassette sold separately), offers riders and racers the speed, range, and robustness needed to tackle any mountain trail. With integrated auto-impact recovery, an impact-deflecting shape, and simple covered pulley solutions, this derailleur withstands harsh trail impacts and still retains its lightning-fast shifting speed and top-level performance.

FEATURES

• Wireless Di2, combined with HYPERGLIDE+ technology, provides smooth, precise, and instantaneous shifts.
  The wide link structure, protector plate design, durable carbon plate, and solid pulley add robustness and longevity.
  The auto-impact recovery function instantly returns the derailleur motor to its original position after an impact.
  Shadow ES offers a slimmer, tougher evolution of Shimano's pioneering chain stabilization concept, Shadow.
  The wedge shape of Shimano's toughest ever rear derailleur deflects more direct impacts and gently bounces off rocks if struck.
  Securely stored in an enclosed space, the battery does not move even on rough terrain, although it can be fully removed for charging.
