Until the 1960s, most professional peloton riders used Brooks saddles. The C13 could herald a return to these historic times.

To achieve maximum weight savings, the frame of the C13 is made entirely from a carbon fiber monocoque structure, reducing the weight. The vibration-damping properties of carbon, combined with a revised, flexible, and vulcanized saddle surface, provide Brooks' lightest saddle with the best comfort. Made with black rivets.
