• Wheelbase. The larger it is and the more it will be flexible.
• Concave of the board. The more it is concave and the less it will be flexible.
• Width of the board. The more it is wide and the less it will be flexible.
• Thickness of the board. The more it is thicker and the less it will be flexible.
That’s why a downhill board has short wheelbase (also for the control of the slides) and deep concave, large widht and it’s very thick.
A pintail, instead, is with large wheelbase, flat, with small width and not very thick.
Flexibility is influenced also by materials with which is built the board.
Traditional longboards are built with wood (maple or birch are the best), 5 to 8 layers can be used to obtain the desired thickness.
More layers are present and the higher is the quality of the board. The thickness of every single layer can be between 1.2 and 3 mm.
We decided to build innovative longboards mantaing the traditional maple wood from Val di Fiemme, Trentino (used for the construction of violins), together with synthetic fibers and epoxy resin.
There are 3 types of synthetic fibers:
• Carbon fiber
Let’s see the difference between them …
It’s the heaviest, the most flexible, absorbs vibrations very well,
when it is impregnated with resin became transparent
It’s the lightest, the most rigid, very difficult to break,
vibrates a lot at high speeds,
It gives great sensibility to the rider.
It has intermediate flexibility between fiberglass and carbon fiber,
and also about weight. It can deform a lot before braking.
Combining different materials with geometrical features we can obtain infinite combinations. Each Stradivarius is built with 10 to 20 layers of wood mixed with synthetic fibers. That’s why every board that we build is unique not only for his aesthetics but also for his mechanics.
