What do you do to improve the ride of a great bike that already features great components? You fit better brakes. The Reaction SLX's Shimano XT hyudraulic disc brakes' powerful, progressive control don't just help keep you safe, they also help you ride faster and have more fun. Combined with the smooth control of the RockShox Judy Silver air fork and easy shifting of the Shimano XT 1x12 gears, you're pretty much all set. The Schwalbe Racing Ralph 2.25in tyres – fast-rolling, smooth and grippy – round out the complete trail explorer.

The Reaction'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. Trail-ready 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.
