The GX Eagle 12-Speed rear derailleur is the next evolution of SRAM’s proven 1x drivetrains. Featuring their proven 1x specific X-HORIZON™ design to provide the same precise, reliable performance you expect from Eagle in and affordable and robust package. Sharing the same technology as its XO1, and XX1 counterparts, the larger, 14-tooth X-SYNC™ lower pulley easily facilitates 10- to 50-tooth cassette capacity, and also adds to GX Eagle's overall smooth-pedalling feel. The Type-3 ROLLER BEARING CLUTCH™ provides quiet, consistent performance and durability.
