When you're hammering your favourite trails as hard as you can, you need to know that your bike isn't going to let you down. That's why we threw all our aluminium frame building know-how at the Reaction TM Pro, starting with a triple butted, hydroformed tubeset for the best combination of low weight and exceptional strength. The tapered head tube, carefully crafted main tube profiles and Boost thru axle at the rear create a torsionally stiff structure that transmits all your effort to the rear wheel - whilst ensuring steering so accurate, it's almost as though the Reaction TM Pro is directly linked to your brain. Internal cable routing complements the frame's svelte looks and means you can spend your time riding, not fiddling with your gears. And we didn't forget comfort, either. Those slim seat stays and the slender 27.2mm seatpost are there for a reason: they help take the edge off the big hits, so long days in the saddle are a pleasure rather than a pain. Is it the ultimate trail-taming hardtail? We think it might be. See for yourself...
