SRAM X01 Eagle 12 Speed Rear Derailleur Black

This new derailleur not only answers the Eagle drivetrain's need for greater capacity, but it's also the next evolution of SRAM's proven, 1x-specific design. The larger, 14-tooth X-SYNC lower pulley allows 10- to 50-tooth cassette capacity in this relatively compact design, and also adds to Eagle's overall smooth-pedaling feel. A new Type-3 roller bearing clutch features a smoother torque curve for a quieter, more consistent operation and feel. The Cage Lock button 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.
