As Mountain Bikes continue to become more diverse, components must evolve. Deore XT addresses the needs of today's riders just like it did when it was first introduced back in 1982 as the world's first MTB group. Revolutionary new designs complement the the latest evolution of traditional designs to give you the right choice for your riding style.

The Shimano XT RD-M771 rear derailleur will work seemlessly with all Shimano LX, XT and XTR components. Narrow Hyper Glide design delivers consistent shifting on 9-speed cassettes.
