Ritchey: Ritchey's history with cyclocross runs long and deep, sort of like the mud sections of your favorite 'cross course. The WCS Carbon Cross Disc Fork is designed from the ground up to manage the unique stresses a disc brake demands – including a carbon layup that resists twisting under hard braking. Decades of experience between the course tape, and building the bikes and components designed to win, inform the performance and design details of this fork. It employs a monocoque construction, it's compatible with standard and integrated headsets, and features carbon dropouts and post disc mount.
