Sram Gx 1X11 Rear Deralleur Long Cage

SRAM GX 1x11 Rear Deralleur Long Cage. The SRAM GX 1x11 long cage rear derailleur brings the proven benefits of SRAM 1x11 Mountain Bike to a more cost friendly price point.

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.
