With its fast-rolling 29er wheels and RockShox 35 Silver air fork boasting 130mm of smooth, easily adjustable travel, you can tell right away that the Reaction TM is a bike that's up for a challenge. We fitted Magura's powerful MT Thirty hydraulic disc brakes – with a 203mm rotor up front and a 180mm at the rear – and a wide 760mm handlebar to ensure you're always in full control, even on the toughest trails. Sram's simple, reliable and wide-ranging NX Eagle 1x12 transmission puts the right gear for any situation within easy reach. And we even fitted a dropper post, so you're ready for those pulse-quickening line choices.
