Colnago racing geometry, developed through years of experience with the greatest champions of the discipline, has proven to be extremely successful – winning many World Cups and World Championships. The A1r CX has all you need for the highest levels of competition.
FORK
Carbon fiber fork blades, paired with a lightweight aluminum steerer tube and designed specifically for disc brakes, combine strength and lightness, and significantly reduce vibrations from the road surface. Colnago goes above and beyond in safety test protocols on forks, ensuring rider security.
HEAD TUBE
Colnago’s tapered head tube design is aimed at creating a solid front end that contributes to handling precision and safety.
SALDATURA SMOOTH WELDING
Linear, precise, technical – the uniform aesthetic is flawless.
BOTTOM BRACKET
Bottom bracket bearings are installed directly into the frame. Thanks to this system, the bottom bracket shell is wider, and can consequently change the design of the down tube – making it wider and stiffer. It also adds to ease of maintenance.
BRAKING SYSTEM
Post-mount disc brakes come standard on the A1r Disc – providing maximum power for shortened stopping distances, and ease of maintenance. The frame uses standard quick-release axles, and the width of rear hub is 135mm.

The term road bicycle is used to describe bicycles built for traveling at speed on paved roads. Some sources use the term to mean racing bicycle. Other sources specifically exclude racing bicycles from the definition, using the term to mean a bicycle of a similar style but built more for endurance and less the fast bursts of speed desired in a racing bicycle; as such, they usually have more gear combinations and fewer hi-tech racing features. Certain of these bicycles have been referred to as 'sportive' bicycles to distinguish them from racing bicycles.
A mountain bike or mountain bicycle (abbreviated Mtn Bike, MTB; or ATB, for all-terrain bicycle) is a bicycle designed for off-road cycling. Mountain bikes share similarities with other bikes, but incorporate features designed to enhance durability and performance in rough terrain. These typically include suspension on the frame and fork, large knobby tires, more durable heavy duty wheels, more powerful brakes, and lower gear ratios needed for steep grades with poor traction.
A single-speed bicycle is a type of bicycle with a single gear ratio. These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle.
