This new GX derailleur not only answers the Eagle™ drivetrain’s need for greater capacity, but it’s also the next evolution of our proven, 1x-specific X-HORIZON™ design. The larger, 14-tooth X-SYNC™ lower pulley allows 10- to 50-tooth cassette, and also adds to Eagle’s overall smooth-pedaling feel. Our 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. And a redesigned, robust mounting system further improves the Eagle™ derailleur’s performance and overall durability.

X-Actuation ratio specifically engineered for SRAM's 1x12-speed Eagle drivetrain
X-Horizon design aligns the parallelogram to a horizontal axis providing constant chain gap across all 11 gears resulting in fast, precise shifts with reduced shifter force
Type-3: features a smoother torque curve for a quieter, more consistent operation and feel, with an incorporated CageLock feature for faster wheel changes and chain service
Large 14-tooth X-Sync lower pulley allows for the 10 to 50 tooth cassette capacity in this compact design
