The Reaction frame's elegantly sculpted lines and super-clean tube joints are part of its appeal, sure. But there's solid practicality there, too. For example, the Internal Cable Routing – which complements the tidy aesthetic – includes cable protection inside the head tube. The 30.9mm-diameter seat tube is ready to accept a remote dropper post. Mounting points at the rear are compatible with our Semi-Integrated Carrier 2.1 and ACID mudguards. A UDH and Boost thru-axle rear end with extra-large chainstay protector is built to be both tough and future-proof. And mounting points under the top tube make it simple to add a compatible ACID tool or other accessory. Form and function, perfectly combined.
The point of a great hardtail is to be simple, robust and reliable. So we gave the Reaction Pro a frame that's both elegant and adaptable, with confidence-boosting handling. And added reliable, trail-proven components, including an air-sprung suspension fork. So that, wherever you're headed, you can just enjoy the ride.
