SRAM's X0 shifters aren't just a pretty face, they actually have an Olympic Gold medal to their credit. But you'd expect that from some of the lightest and quickest shifters out there and some of the easiest to use, too. They actually allow you to shift multiple gears at once, and with their simple twisting action, you never miss shifts. Ride light, shift fast and go for the gold with X0. FEATURES Compatible with almost all MTB rear shifters Ball bearings at the rotation interface make for a smooth-feeling shifter that is very durable.
