Colnago A1r 105 Mens Road Bike - 2017 - White/Black

Can be purchased using Cycle to work

The Colnago A1r 105 Mens Road Bike utilises a high performance aluminium frame that has been thoroughly studied and designed to ensure that it follows the legendary Colnago criteria. Speed, fluidity, stability and lightness are truly in its DNA. 

The aesthetics of the A1r are enhanced through the use of new construction and welding technologies. Particular attention is placed on the orientation of tube junctions, to ensure maximum torsional rigidity without sacrificing comfort. 

Following this same train of thought, the choice was made to use a 27.2mm diameter seatpost - smaller and more flexible, but also lighter than a larger diameter post. For optimal comfort and weight savings, the choice was made to use a fork with a carbon fibre steerer tube. 

A press-fit bottom bracket and semi-integrated cable routing are also prominent features on this new frame. 

The A1r is equipped with full Shimano 105 gear componentry that offers a choice of 22 gears. The finishing kit is comprised of Colnago’s own components including their Artemis R28 wheelset, handlebars, stem and brakes.
