Product Description


SRAM GX Eagle 12-Speed Rear Derailleur

As well as enabling their 12-speed drivetrain, the GX Eagle rear mech features SRAM's latest derailleur innovations.

Here's how SRAM describe this mech

'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 enables it to work with a 10-to-50 tooth cassette, and also adds to Eagle's overall smooth-pedalling 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.

Only Eagle™ is a complete system-engineered drivetrain designed, tested and proven to deliver the lightest, highest-performing, most durable system for all riders on any trail.

Eagle™ technology provides an expanded, optimum, gear range making you fast on the flats, giving you control on the climbs and unleashing your speed on the descents. Compatible with all levels of Eagle drivetrain systems
