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.
Frame description The Reaction TM's triple-butted, hydroformed aluminium chassis encompasses all our frame-building know-how to create a bike that's fast, light and tough. The Boost thru axle, complex-profile down tube and tapered head tube combine to ensure accurate steering, even on rough trails. But we didn't forget comfort – slimmed-down seatstays will help keep you riding 'til sundown. And internal cable routing keeps mud and water out of your gear cables, so you can spend more time riding and less time wrenching.
Find your size!
Enter your height and inseam below and click on 'Calculate my frame size' to see which size you need. You measure your inseam as follows:
1. Stand barefoot with your heels against the wall. Place your feet about 6 inches apart.
2. Grab a book and place it between your legs, with the short side of the book against the wall. Press the book up against your crotch, mimicking the idea of a bicycle saddle.
3. Measure the length from the top of the book to the floor, the distance you measure is your inseam.
