The SRAM GX Eagle rear derailleur features a large 14-tooth X-SYNC lower pulley allowing a 10- to 50-tooth cassette, and also adds to Eagle’s overall smooth-pedaling feel. The 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. And a redesigned, robust mounting system further improves the Eagle derailleur’s performance and overall durability.
