The result? Seriously impressive power transfer, steering and overall responsiveness thanks to our Agile Ride Geometry. We haven't forgotten comfort, though - the slender 27.2mm seatpost and slim seatstays work together to help take the sting out of the trail, so you can go harder for longer.
Internal cable routing maintains the frame's sleek looks as well as clean gear shifting, and we made sure that an upgrade to a Stealth dropper post is easy. With a PressFit bottom bracket and integrated headset, we've ensured the entire chassis is as light as we could make it. Less, after all, is more. Less weight means more speed...
The Reaction represents something rather special: it's CUBE's Formula One class of mountain bikes. Light, stiff, responsive and built for one purpose only - to go as fast as possible from A to B.
To that end, we've poured all our accumulated carbon frame building experience into it. Featuring fast-rolling 29er wheels, the Reaction frame makes use of our C:62 carbon layup and features neat design touches like a Boost 148 rear axle and Stealth dropper post cable routing. Kitted out with a smooth, easily adjustable RockShox air fork, CUBE-built wheelset and a slick, reliable Shimano SLX and XT 2x11 transmission, we reckon it's missing just one vital component: you.
