Shimano  XT Shadow Rear Derailleur RD-M780

Designed specifically to optimize the shifting performance of Shimano's 10-speed Dyna-Sys drivetrain, the Shimano Deore XT Shadow rear derailleur performs flawlessly, smoothly and reliably in all conditions. The RD-M780 Shadow has a low-profile design that keeps the chain from slapping the chainstay and helps protect the derailleur from getting up close and personal with rocks, roots, logs and other potentially damaging, trail-narrowing impediments. Precise shifts and built-in longevity -- what more could a trail rider ask for?
