Compatible with XX, X0 & Elixir CR Mag & all SRAM MM-Compatible Shifters. MatchMaker X is a singular clamp that can mount both the brake lever and the shifter (depending on the variant), reducing weight and redundancy, while maximising adjustability and bar space. With the addition of the shifter clamp you can position your shifters on the bar medially/laterally as you like, and the shifter lever can be repositioned as well. You can also rotate them on the bar to put them exactly where you need them.
