Completely revised for 2022, the brand-new Reaction Pro's sleek looks are thanks to its smooth-welded head tube and seat tube junctions. It incorporates a threaded bottom bracket and internal cable routing for long-lasting service and simple maintenance. There's even a flat disc mount that integrates seamlessly with our kickstand mount, and integrated mounting points for ACID mudguards and carrier. Updated geometry includes a lower top tube and tapered head tube for more confident handling, cables run internally for reduced maintenance, and there's plenty of room to run wide, grippy and comfortable 2.25in tyres. And, as your skills increase, there's scope to fit a dropper post upgrade.

When we sat down to design the Reaction Pro, we wanted the perfect blend of function, reliability and performance. So we started with the precision of Shimano's XT 1x12 transmission, because it offers an enormous range and an unparalleled reputation for precision. We added Shimano XT hydraulic disc brakes for their superb all-weather stopping performance to help keep you safe, whether you're out in the hills or battling across town. And we finished with the RockShox Judy Silver air fork, because it combines easy adjustability and a remote lockout with trail-smoothing alacrity. It's the complete package.
