It is a revolutionary bicycle, which has been developed so that it can be used as a comfortable means of transport, contrary to the belief that a bicycle with this technology was only designed for sports. The X1-METROPOLE is a very high-end bicycle, with which any user can reach their destination or work, with all the comfort and without having to maintain an uncomfortable posture. In addition, it has a luggage rack in the rear that also functions as a fender, and a small compartment embedded in the horizontal tube, which makes it very useful for transporting small objects such as keys, mobile, etc ...
We use the word revolutionary because it is not a typical city bike, with 28 ”wheels, steel frame, handlebars and fenders. This is a highly engineered carbon fiber bike with 26 ”wheels, Carbon lined Magnesium suspension fork, and a very avant-garde design that breaks the mold of conventional city bikes.
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 of 140 ° C in an autoclave (vacuum container) at a pressure of minus 6 bars of vacuum. This technology allows to create 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.
