When we sat down to design the Reaction Pro, we wanted the perfect blend of function, reliability and performance. So we started with the precision of Shimano’s XT 1×12 transmission, because it offers an enormous range and an unparalleled reputation for precision. We added Shimano XT hydraulic disc brakes for their superb all-weather stopping performance to help keep you safe, whether you’re out in the hills or battling across town. And we finished with the RockShox Judy Silver air fork, because it combines easy adjustability and a remote lockout with trail-smoothing alacrity. It’s the complete package.
