Nack: Nano carbon fiber rail. Carbon fiber, Kevlar and aluminum filaments seat-post clamp area, treated with the production process called Braided Carbon Rail (BCR).
This is done in order to obtain “the perfect fusion” and uniformity of the several type of fibers and materials. The result is a balance structure and resistant to penetration.
Active Density: It is the system patented by PROLOGO that combines multiple base stiffnesses and multiple padding densities for a new level of comfort.
ESD Design: The Ergo Shape Design (ESD) is the result of ergonomic and biomechanic studies and tests done by PROLOGO in the last few years.
Carbon Injection Monocoque: 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.
