CUBE Reaction Pro
With the Reaction Pro, CUBE 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. CUBE 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.
Frame
A great-riding hardtail starts with a great frame. The Reaction's double-butted 6061 aluminium frame tubes, tapered head tube and mechanically formed down tube provide a strong, efficient backbone. CUBE added neat, hidden rack and mudguard mounting points for extra versatility. Internal cable routing for clean looks and lower maintenance. And built the whole lot around our acclaimed Agile Ride Geometry, so you can be assured of a comfortable, lively and safe ride - wherever your adventures take you.
