SRAM GX 1x11 Rear Deralleur - Long Cage
The SRAM GX 1x11 long cage rear derailleur brings the proven benefits of SRAM 1x11 MTB to a more cost-friendly price point. The GX 1x11 uses X-Horizon technology to eliminate chain slap and improve drivetrain stability when using a single chainring up front. X-Sync pulley wheels grab onto the chain to help keep it firmly in place, but without a loss of drivetrain efficiency. X-Actuation shifting technology eliminates slop and shifting variation across the entire enormous range of SRAM's 10-42T cassette.
