Among the CUBE mountain bikes, Reaction can safely be defined as the Formula 1 series. Light, rigid, reactive and built with a single objective: to achieve the highest possible speed on dirt roads. And to achieve it, we have completely reworked it for 2018. With fast 29 "wheels, the new Reaction frame is the result of our C: 62 carbon technology, thanks to which we have made it even lighter, stiffer and more responsive to his predecessor. We did not think it was possible, but those perfectionists of our engineers thought otherwise: With a smooth air fork, wheels assembled in the CUBE plant and the reliable 2 x11 Shimano SLX and XT transmission, Reaction misses a single component: you.
