SRAM XX1 Eagle 12 Speed Rear Derailleur

This new derailleur not only answers the Eagle drivetrain's need for greater capacity, but is also the next evolution of SRAM's proven, 1x-specific X-HORIZON design. The larger, 14-tooth X-SYNC lower pulley, allows 10- to 50-tooth cassette capacity in this compact design, and also adds to Eagle's overall smooth-pedaling feel. Their new, Type-3 Roller Bearing Clutch features a smoother torque curve for a quieter, more consistent operation and feel. Cage lock has been moved back and out of the way, protecting it from trail debris. A redesigned, robust mounting system further improves the Eagle derailleur's performance and overall durability.
