Rail light-alloy steel, highly resistant to traction, and torsion, for its physical characteristics and light weight, is used in the aviation and aerospace industry. T-Irox then turns out to be a rail with a good balance between weight and strength, that doesn? t fear the normal stress that addresses a bicycle.

After countless hours of R&D, the Prologo engineers have developed a new production process for injected carbon fiber, to create a ?Monocoque injected? base. This results in less weight (about 15%), increased stability and even an improved overall finish of the saddle.

It is the system patented by Prologo that combines multiple base stiffnesses and multiple padding densities for a new level of comfort.
