2017 Colnago Concept
Colnago unveiled its first ever aero bike in a little castle in Germany just up the road from Eurobike. Fittingly, it was Ernesto Colnago himself who revealed it to the world. According to Colnago, his aim for the Concept and every other bike he produces is “to make cyclists faster.” And he delivered on that promise. So now there are three bikes occupying that highest rung in the Colnago hierarchy: The C60, V1r and the Colnago Concept.
Like many wind slicing aero bikes the Concept was developed in the wind tunnels. Colnago went through 41 versions to get the result that became the Concept: the ultimate in aerodynamics and speed.
The Concept weighs in at 995g without paint and 400g for the fork. So it won’t win any lightweight awards but it’s no heavyweight either. The stiffness numbers have this bike falling within just a few percentage points of the C60 and V1r, but it has less vertical compliance. But there is a flipside to this: at a zero-degree yaw angle you save 20 watts at 50 km/h. Do you care about saving watts? Saved watts means more speed at the same effort. And Colnago states that there are aerodynamic savings at every one of its eight sizes. That’s a big deal, and in the world of aerodynamics every bit is important.
The front of the bike is the most important part when it comes to aerodynamics, as it is the only part of the bike that meets clean air. Because of this, Colnago has innovated the front end to be as aerodynamic as possible. They took the leg shape from the V1r, but modified it to have more tire clearance and added aero profiling
Another aspect of the front end to receive innovation is the head tube. In the field of aerodynamics every bit counts so the headtube of the Colnago Concept sports an hourglass aerofoil figure. This shape helps it slice through the wind. It has a conservative taper as well, 1 ¼ to 1 ?, with a custom headset with cups constructed with nylon, carbon and elastomers. The reason Colnago innovated the custom headset is they wanted to avoid the harsh ride of some aero bikes. The headset reduces road vibrations by partially isolating the fork from the frame. So not only do you have a bike that is fast, you have one that is comfortable too.
