The Reaction series represents something rather special - it's CUBE's Formula One class of mountain bikes. Light, stiff, responsive and built for one purpose only: to get from A to B as quickly as possible. To that end, we've poured all our accumulated carbon frame-building experience into it. Short chain stays, a Boost thru axle at the rear and tapered head tube up front all contribute to impressive steering accuracy and incredibly efficient pedalling, all wrapped up in our Agile Ride Geometry for impeccable control. Fast-rolling 29er wheels make light work of the trail, aided and abetted by slender seat stays for more comfort and a RockShox Judy air fork for superb control in the rough. We even incorporated cable routing for a stealth dropper post upgrade, if that's where your ambitions take you. And, as you'd expect, our design team selected Shimano's superb 1x12 XT and SLX components for their unparalleled gear range and legendarily smooth, reliable performance. It's all set to take on any cross-country challenge, but it's missing one vital component: you.
