The Selle SMP F30C Carbon Rail Saddle is specially designed for the comfort of riders with medium to wide sit bones. This performance saddle is ergonomically engineered to allow maximum range of motion around the saddle. A wider rear and deeper cutout make it more comfortable and versatile than ever. Both the center of the saddle and the rear have ergonomic cutouts which prevent stress on sensitive areas while also lowering the overall weight of the saddle. This version of the F30C utilizes unidirectional carbon rails for a lightweight setup and excellent shock absorption. A carbon reinforced nylon body combined with foam elastomer padding add to the performance and comfort balance of the saddle. Ready to take on any riding style from road to mountain or even an urban commute, the Selle SMP F30C never sacrifices comfort for performance.
