SHIMANO XT Shadow Rear Derailleur for 10-Speed (RD-M773) - 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 latest evolution of traditional designs to give you the right choice for your riding style.

Shimano has been making mountain bike drivetrains for more than three decades, including eight generations of Shimano Deore XT (the original MTB drivetrain) and six generations of its flagship XTR group. Each generation is a reflection of the riding that defined the sport and the technology that defined the era. True to this legacy, our next-generation Dyna-Sys drivetrain brings with it the legendary quality, durability and performance riders expect from Shimano, all packaged to meet the ever-evolving demands of today’s riders.

Thanks to new, more direct Shadow cable routing and the reduced cable tension, Dyna-Sys is less sensitive to contamination, cable stretch and cable routing concerns, which all adds up to more consistent performance in even the roughest terrain - the kind of trails that rattle molars loose and make suspension components work overtime to keep pace.
