2017 Colnago A1r 105 Bike



We all know that Colnago makes amazing carbon superbikes, but it may be less well known that they are still creating high quality aluminum frames at a very reasonable price. It’s a fantastic deal: all the craftsmanship you’d hope to have in an Italian bike, but at the sort of price point that makes it an easy addition to your collection.

Available as a complete bike with the Shimano 105 groupset, the Colnago A1r offers an ideal mix of lightweight construction methods and attention to the long term durability of the frame. The aluminum welds have been kept beautifully smooth, and the tube junctions have received particular attention to make sure that the torsional rigidity will keep the frame ready for every acceleration. But don’t worry about it being a bone shaking ride since Colnago’s designers have added elements to ensure a comfy ride. The 27.2mm diameter seatpost, which is smaller and as a result more flexible than a bulky post, will add a welcome springiness to your back end. And for the front, they have used a mix of carbon fork legs and an alu steering tube to get the rigidity/compliance mixture just right without heaping on the extra costs. Then the tapered head tube will increase the strength and enhance the sharp handling so you can enjoy your favorite twisty descent.

Colnago has also given the A1r a press fit bottom bracket so that they can design not only the bottom bracket, but the down tube and seat tube to be mega-sized, increasing rigidity and durability of that core intersection on the bike. Internal cable routing keeps the look clean and aero, and finds the smoothest route from the hoods to the derailleur so that you can count on that smooth shifting we all love with Shimano. The A1r slips neatly into the Colnago lineup since it offers all the racing gravitas that you can expect from one of their bikes raced at the WorldTour level, but you don’t have to have a pro contract to be able to afford one. The high quality aluminum frame combined with the reliable and durable Shimano 105 components means that you can use this bike for all your longest rides and even as a high performance commuter if you feel like getting some miles in before and after work.

The Colnago A1r comes in six sizes and two frame colors, so that you can certainly find the right match for your size and sensibilities.
