We built the Reaction Race for one thing and one thing only: to go fast. Best tie your shoes a little tighter when you climb aboard, then, because this bike will take everything that you've got and translate it into rapid forward progress. Completely reworked for 2018, we took all the best bits of the previous Reaction, made them better, and added some completely new features - like Stealth dropper post cable routing and a thru axle rear end. With a buttery smooth RockShox Judy fork, powerful Shimano Deore hydraulic disc brakes and SRAM's Eagle GX 1x12 transmission, the Reaction Race sets new standards in its class. This is a bike that feels as good out on the trail as it does on the race course, and we reckon that's a winning formula.
With their makeover for 2018, our Reaction frames represent the state of the art in aluminium frame construction. Lighter, stronger, more efficient: that's the way we roll, and if can't make it better we'll leave it alone. So the Reaction Race has double butted 6061 aluminium tubes for superbly efficient power transfer, amazing comfort and the lowest possible weight. It boasts internal cable routing, so your gear shifts stay cleaner for longer, even in filthy trail conditions. We upgraded the rear end with a Boost thru axle and fitted a fully integrated, sealed bearing headset - so torsional rigidity is improved and the bike goes precisely where you want it to. And there's even cable routing for a Stealth dropper post, making it easy to upgrade. With our Agile Ride Geometry (ARG), it all adds up to an inspirational ride.
