The GX 11-speed Trigger Shifters bring many of the high-end technologies from XX1 and XO1 into a more affordable realm, keeping our drivetrains running smoothly for many riding seasons to come. This includes the X-Actuation technology that keeps shifting precise and dependable across the entire cassette. Like the Exact-Actuation ratio for its road groups, SRAM has deviated from its bread-and-butter 1:1 pull ratio. GX uses SRAM's updated cable-pull ratio system to deliver a more uniform and accurate derailleur movement, with less thumbforce required from the user. Please note that these shifters are for 1 x 11 and 2 x 11 SRAM mountain drivetrains. They will not work with Eagle 12-speed.
