With the Reaction Pro, we wanted the perfect blend of function, reliability and performance. So we started with Shimano's SLX and XT components for the 1x12 transmission, because they offer a huge range and an unparalleled reputation for precision. We added Shimano XT hydraulic disc brakes for superb all-weather stopping performance, whether you're out in the hills or battling across town. And finished with the RockShox Judy Silver air fork, which combines easy adjustability with trail-smoothing alacrity.
