When we set out to build the ultimate lightweight trail bike, we began with our best-in-class C:68X® carbon lay-up. With slender tube profiles, fastidious design and exhaustive testing, we finished with a frame that weighs around 1600g. Designed around 444mm chainstays with clearance to comfortably run 2.4in tyres, there's even an Acros angle adjustment insert to allow fine-tuning of the head angle. 110mm of rear-wheel travel and 120mm up front – combined with the agility of a super-responsive frame – is a potent combination for dissecting even the trickiest sections of trail.
