SRAM GX 1×11 Rear Derailleur

The SRAM GX 1×11 Speed Rear Derailleur is engineered for smooth, reliable shifting action-from the larger upper pulley offset to the 12-tooth X-SYNC pulley wheels. By eliminating unwanted chain movement, X-HORIZON shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with CAGE LOCK technology, wheel removal and installation are easier than ever.
