GX 2x11 Trigger Shifters bring many of SRAM's high end 11 speed technologies into the realm of the affordable and work with its huge 10 42 cassette. This includes the new X Actuation that keeps shifting precise and dependable across the cassette. Like the Exact Actuation ratio for its 10 speed road group, SRAM has deviated from its bread and butter, 1:1 pull ratio. GX uses SRAM's cable pull ratio system to deliver a more uniform and accurate derailleur movement, with less applied force required from the user. The shifter also comes with a MatchMaker compatible clamp in order to simplify accessibility and to create a clean aesthetic by placing your Avid or Guide levers and RockShox PushLoc suspension controls on the same clamp with your shifters.
