Getting as fast as possible from A to B cross-country demands components that won't let you down. That's why, for the Phenix C:68X SLX, we started with Sram's all-electronic XO Eagle Transmission groupset, to put a huge range of gears at your fingertips. A RockShox SID SL Ultimate fork, lightweight Newmen Advanced SL X.A.30 wheels, grippy Schwalbe 2.25in tyres and ultralight Schwalbe Aerothan inner tubes all help keep the rubber side down for speed and control. The integrated carbon bar/stem combo is light and comfortable. And powerful Magura MT8 Pro brakes mean you can go faster, for longer.
We know a thing or two about making fast cross-country race frames, but the new 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.
