Sram GX rear derailleur

Leveraging SRAM´s legendary shifting history, the GX rear derailleur delivers incredible speed and precision. X-ACTUATION™ technology provides crisp, consistent shifts by eliminating slop, while the ROLLER BEARING CLUTCH™ ensures maximum drivetrain stability on the most punishing terrain. This combination, along with the X-HORIZON™ design, virtually eliminates derailleur bounce and chain slap. For ultimate convenience, CAGE LOCK™ technology makes wheel and chain installation faster and simpler than ever
