Specialized Crux Comp Cyclocross Bike 2021

Specialized’s Crux Comp comes from a long line of successful cyclocross bikes, with victories aplenty at every level from grassroots to World Championships. This latest FACT 11r carbon frame has shed 400 grams and now weighs around 900 grams depending on size and paint scheme. In a sport which involves not just plenty of rapid accelerations but also shouldering the bike numerous times per lap, the weight reduction is very welcome. Carrying comfort is also aided by the flattened top tube and larger front triangle opening, which, along with the aggressive angles for fast handling, marks it out as a thoroughbred CX bike rather than a gravel machine.

The DT Swiss R470 Disc wheels with 33mm Specialized Tracer Pro tyres are both tubeless-ready, so can be easily run without inner tubes, which is particularly useful for low pressure running and grip off-road. Mud clearance is excellent as the frame offers 8mm per side with regulation 33mm tyres, ideal for avoiding getting slowed down by mud and grass clogging things up.

Braking duties are carried out by SRAM’s Force level hydraulic disc brakes, offering consistent and powerful retardation even in the worst winter conditions. SRAM also take care of shifting courtesy of their 11-speed Force 1x groupset, with the large single paddle being easy to operate in extremis or with cold, wet hands.
