Colnago A1R 105 Aluminium Road Bike - 2017

The Colnago A1R 105 aluminium road bike is a modern classic from Italian master bike builders Colnago. Recognised around the world as a bike brand that is rich in craftsmanship and steeped in racing history the A1R reflects their heritage with every functional and aesthetic detail being carefully considered before it’s signed off. At the heart of this bike the aluminium frame has been designed following the legendary Colnago criteria – speed, fluidity, stability and lightness are in its DNA. With a clever new construction technique using new welding technology the A1R provides maximum torsional rigidity without sacrificing comfort while the smooth welds at each frame junction give a seamless, fluid finish closer in appearance to a carbon frame rather than an aluminium frame.



With comfort and compliance at the forefront of Colnago’s design brief the A1R also features a diameter seatpost which is more flexible than a seatpost of a larger diameter and a full carbon fibre fork to help dampen road vibration while at the same time providing precise tracking and confidence inspiring bike handling. A press fit bottom bracket also helps provide a super-stiff frame junction to ensure that all of your power transfers directly through the frame. A full Shimano 105 5800 groupset and a pair of lightweight but durable Colnago Artemis wheels completes this competitively priced package that features plenty of technology that has trickled down from higher specced bikes in the Colnago range.

Colnago bikes generally suffer from the same criticism, they are overpriced and under-specced for the money you pay, and they're not the lightest of bikes. People also point out that apart from the top end or steel bikes they are manufactured in the far east. But the bikes have heritage and kudos, they look sublime and the frames ride well, the equipment is Shimano 105, compact FSA chainset and Colnago calipers. The kit is fine Deda bars etc. It boils down to are you willing to pay for a nice looking frame and the brand? It's a 'fairly' light frame for aluminum and rides very nicely. But it's Colnago and the quality of the groupset and frame are about right. The bike looks great and it has the brand name if that matters then you can't go wrong.
