Blink, and you'll miss it – because the Phenix C:68X SLX is designed to be fast. There's a hint in the E*13 Helix Race carbon crank, which is power meter-ready for optimised training and race course performance. The theme continues with a lightweight Newmen Phase 30 wheelset, shod with fast-rolling Schwalbe Racing Ray and Racing Ralph 2.35in tyres and held in check by Shimano's range-topping XTR hydraulic disc brakes, so you can brake harder and later. A smooth, light and easily configurable Fox 32 Float Factory SC fork with remote. And – the icing on the proverbial cake – Shimano's electronic XTR Di2 1x12 gears, putting a huge range of ratios at your fingertips so you can reel in and pass the competition.

Frame description
We know a thing or two about making fast cross-country race frames, but the Phenix 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.
