Product Description
Ritchey tires have won more World Cup races than any other. Our SpeedMax series consists of semi-slick designs for minimal rolling resistance, maximum acceleration and all-out speed in hardpack conditions. Our Z-Max series is based on Z.E.D. (Z-Max Evolved Design) philosophy, designed for optimal traction and handling in a variety of conditions. Our newest additions to the Ritchey WCS™ lineup build on that heritage: the Z-Max Premonition™, Intuition™ and the SpeedMax Beta™ combine new Dual Compound rubber with world cup winning Vector Force Analysis™ tread technology. The result is the next generation of tires worthy of our name.
