SRAM XX1 Eagle 12-Speed Type 3 Rear Derailleur, Black with Gold Trim

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. SRAM's 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.
