The Reaction HPA Pro, a modern, performance aluminum hardtail, has once again been further refined for 2019. Still with an extra-wide Boost thru-axle at the rear, for a stiffer wheel and ditto rear-train. And the option to mount an adjustable seatpost, for more security in technical descents. But now with smart, user-friendly mounting bosses on the swingarm, allowing you to quickly attach a mudguard and/or luggage carrier without disturbing the clean looks. This year's specification list is again packed with high quality components, from an easily adjustable RockShox air suspension fork to a buttery smooth shifting 2x11 SLX/XT transmission from Shimano. This bike screams for challenging singletracks! Speed, dynamics, control and comfort, that's what the Reaction Pro stands for!
