SRAM MMX Disc Brake Lever Clamp – Black Titanium Bolt. SRAM MatchMaker X lever mount is a singular clamp that mounts both the brake lever and the shifter reducing weight and redundancy while maximizing adjustability and bar space. 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. MatchMaker X also supports the XLoc remote suspension.
