Our reaction Pro frame was already well-regarded in the hardtail world. We kept all the best features - like the mechanically formed, double butted 6061 aluminium main frame tubes and the stiffness-enhancing tapered head tube - and added some new ones to make it even better. The Boost-compatible rear - with thru axle - is stiffer and stronger than before, so you can push your bike safe in the knowledge that it'll respond to your every whim. The fully integrated sealed bearing headset is hard-wearing and sleek, with a low stack height that doesn't compromise handling. We even added Stealth dropper cable routing to the existing internal cable setup, so that you can add a dropper post at a later date. The slender seatpost contributes to ride comfort and, of course, it's all put together around our Agile Ride Geometry (ARG), for the best blend of comfort, pace and agility.
