A seriously rapid bike demands serious components in the pursuit of speed. Which is why, for the Reaction C:68X SLX, we began by selecting a Fox 32 SL Performance SC fork with remote lockout – to help you keep the rubber side down and pointing where you want it. Sram's GX Eagle Transmission 1x12 gears serve up the huge range and crisp, accurate shifts you'd expect. A Newmen Phase 30 wheelset shod with Schwalbe's Racing Ray and Racing Ralph 2.25in tyres delivers rapid acceleration and all the grip that you need. And, last but by no means least, Magura MT8 Pro hydraulic disc brakes give you the power you need to brake harder, later, and stay on the gas for longer.

Frame

We know a thing or two about making fast cross-country race frames, but the Reaction C:68X moves the bar even higher. How? For starters, we used our premium C:68X® carbon for the ultimate in low weight, high strength and ride comfort. We redesigned the seat tube junction to incorporate an integrated seat clamp. It's a small touch, but – along with Internal Cable Routing – it complements the frame's clean aesthetic and elegant, organic lines. And there's an adjustable angle headset, so you can tweak your bike's handling to suit your own taste.
