Characteristics

Aerodynamic studies have shown that the air resistance that a rider exposes on his bicycle is around 75-80%, and that the resistance of the bicycle is between 20 and 25%. This resistance is concentrated in those parts that enter the air before and which are: the handlebars, the brake levers with their cables, the steering tube, the fork and the width of the front wheel cover or tubular and then the follow the seat tube and the rear seatstays.

It is also proven that a tube with a drop-shaped section is more aerodynamic than a round or square tube. Aerodynamic studies have shown that the drop takes the most efficient shape when entering the air in a free fall.

All these studies helped to choose the most suitable shape for the tube sections, and from this moment on, Costantino designed the geometry of the frame to help the rider maintain an aerodynamic position while being comfortable. By also applying Monocoque manufacturing technology, the X1-CRONO frame was born.

This process has the particularity of offering a structural continuity that provides a multitude of advantages to highlight:

  • Greater comfort.
  • Greater rigidity.
  • Minimizing the chances of human error in the manufacturing phase.
  • Refined aesthetics.
  • Reduction of aggression with the environment.
  • Decrease in weight.
  • And as it does not have union areas, it lacks possible squeaks.

An important phase in the process of making the painting is the stratification of the fabrics pre-impregnated in resin, which amount to up to a hundred tiny pieces of varied shapes with different mechanical characteristics, which vary according to the functionality of each piece and the site that occupies inside the frame structure.

Once the stratification step is finished, the frame is subjected to a heat treatment in an autoclave (vacuum container) at a pressure of minus 6 bars of vacuum and a temperature of 140º C. This technology allows to make a composite structure with a perfect exterior finish, and a homogeneous compaction of the interior sheets throughout the entire frame, which gives it a fundamental characteristic of mechanical resistance.

The end result is the birth of a very special painting, based on the wisdom of the choice of materials, the type of fabrics and the correct placement of various pieces at the key points inside the painting.

Paintings that at first glance appear the same as ours may have some differences that only an attentive and expert eye can identify, and sometimes neither can this due to the fact that the differences are found in the internal structure of the painting. Materials can be noticeably different from ours, without realizing it. These differences can make a mockery of those manufacturers who say that their frames are monocoque when they really know they are not, and they also use cheaper materials that can seriously reduce the mechanical properties of the frame and have terrible consequences imaginable.
