Select options SRAM GX Eagle™ 12 Speed Upgrade Kit R7,000.00 R5,699.00 SRAM Eagle™ drivetrains are the only 1x drivetrains that are fully system engineered for optimal performance. Eagle™ drivetrains are designed, tested and proven to deliver the lightest, highest-performing, most durable systems for all riders on any trail. Eagle™ 12 speed technology provides an expanded, optimum, gear range that allows you to realize your bike’s potential beyond where it has ever been. The Eagle GX Trigger Shifter is the control center of the Eagle™ drivetrain. Its internal works have been updated to include a 12th gear, and improved to enhance trigger feel, precision and durability. The new GX 12 speed 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. Designed with SRAM’s Eagle™ geometry, the GX Eagle™ chain features solid pin construction, Eagle™ PowerLock® and smooth, efficient shifting that you can count on every time out. Every SRAM GX Eagle™ component is 100-percent compatible with all levels of SRAM Eagle™ drivetrain systems. * Includes SRAM GX Eagle 12 speed chain.
