The reason for sloping

In addition to the frame size, of course, the geometry and angles of the tubes are also parameters that directly influence the rider’s position in the saddle, resulting in a comfort or performance-oriented setup, as the case may be.

In this respect, among the many variables to be taken into account when choosing a new frame, there is so-called “sloping“.

“Sloping” is an English term and in cycling refers to the crossbar of the bicycle which is not parallel to the ground, but sloped downwards at the rear.


This type of solution, first used in America, was adopted for the first time on Mountain Bike frames, before being quickly extended to the world of “road bikes” and becoming in fact a standard feature, thanks to the definite benefits it provides.

What are these benefits? A sloping which is not too accentuated, like that adopted by Colnago frames (about 2 cm), forms a triangle of ideal compactness, with superior rigidity and responsiveness, i.e., less subject to twisting or bending, which ultimately allows the cyclist to push on the pedals more effectively.


The more compact design also allows a small saving in terms of weight, and makes the bike aesthetically pleasing and “balanced” even in the smallest sizes.

Moreover, on these frames, the seatpost offset is greater than that of the geometries with the crossbar not inclined, and this visually translates into a slimmer and more aggressive bicycle.
