A flat saddle built for road riding. This saddle is made with Prologo\'s C3 carbon composite base, a special compound that has allowed Prologo to make a saddle under 145 grams but still maintian the stability and performance of heavier saddles. It also comes with a nack rail, a nano carbon fibre fused with kevlar and aluminium to create a superlight rail that is balanced and will not deform. This saddle is also used by Saxo-Tinkoff\'s Alberto Contador. 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. Specifications: Size (mm): 270 x 132 Weight (gr): 149 Base: C3 base Rails: Nack Cover: Microfiber Padding: Light Foam
