2020 Colnago K.One

Though Colnago has never lost its mojo, there was a time several years back when it had faded from the front ranks of pro team sponsorship. Though no one would argue the quality of the bikes suffered, now that the Italian brand is back at the top of the league, it is possible to detect a certain excitement in each new iteration of the bikes. The Colnago K.One time trial bike is a prime example. You can’t sponsor a WorldTour team without having a kickass time trial bike, and then the rest of us TTers and triathletes get to take advantage of all the new neat advancements.

Unsurprisingly, the K.One has been developed in the wind tunnel, using the Colnago engineers’ extensive knowledge of fluid dynamics. So there’s no doubt this is a very sleek looking bike. And integration was key to a lot of the design. One of the first things you’ll notice is that they have hidden the front brake, which remains easily accessible at the top of the fork, under a flexible cover. It keeps everything aero, light, and easy to maintain, which is very important if you are your own mechanic at your triathlons. Similarly, the bottle-cage and bottle have been integrated seamlessly into the shape of the downtube, reducing the drag you’ll be suffering. And then there are neat little things like that window in the top tube where you can store your electronic control out of the wind but still easily accessible. We can thank WorldTour sponsorship for those are the little additions since the professional mechanics won’t want to have to fiddle with batteries and zip ties any more than we will.

The K.One’s geometry has been developed to be seriously stable at the elevated speeds you’ll likely be traveling. Whether you are on a dead straight, flat road, or negotiating a twisty descent, you are going to want to feel secure enough in the bike’s handling to stay on the aerobars as long as possible. Otherwise, you’ll just be losing time to your competitors. But you’ll also need to be comfortable in that position otherwise you’ll be losing power and your performance will suffer. So Colnago has made the K.One highly adjustable. Colnago has developed the front end to keep all transition points smooth and increase the rigidity of the region, so things like the handlebar and stem seamlessly melt into the top tube to keep that important area as aero as possible.

For the bottom bracket, Colnago goes with their ThreadFit82.5, which neatly squares the circle regarding press fit width and rigidity with threaded durability. Considerably more exciting is the fact that Colnago has partnered with Ceramic Speed to create their threaded, wider bottom bracket, with best in-class bearings. It makes this all important area seriously stiff so that your leg power will transfer to road speed.

The Colnago K.One is UCI approved, so you can use it if you are gearing up for a UCI sanctioned event. And it will be a demon on the Ironman circuit. It guarantees the comfortable confidence that will inspire you to tackle the more difficult races of the season and help you get your times competitive for Kona.
