An outstanding lightweight stiff balanced road saddle ideal for long days on the bike. The blend of technologies from Prologo make this saddle excellent value for your money. Specifications: Size (mm): 280 x 134 Weight (gr): 177 Base: Carbon Injection Monocoque Rails: Nack Cover: Microfiber Padding: Light Foam Nack Nano carbon fiber rail. Carbon fiber Kevlar & 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” & uniformity of the several type of fibers & materials. The result is a balance structure & resistant to penetration. 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 & even an enhanced overall finish of the saddle.PAS System The PAS system is a processing of the base of the saddle the hole or channel has been designed to eliminate pressure to a zone of support delicate as the pelvic area. Prevents pressure peaks in the prostate area ensuring optimum comfort. This is a system studied designed & recommended to eliminate pressure & numbness in the pelvic area-prostate.
