The GX 1x11 rear mech is pert of Sram's next generation series where they are bringing 11 speed to everyone. Don't think that it is not going to have the same qualities as the other 1x11 systems, because it does. The X-Actuation eliminates chain slap and shifting variation. Cage Lock technology makes changing the wheel easier as it keeps the mech tensioned. The Roller Bearing Clutch keeps the drivetrain stable even in the harshest of terrains.
