The Northern California Coast and Santa Cruz Mountains are steeped in road riding history. To honor it, we named our new top-level crank Zayante, after the fabled redwood-covered climb so-named – secret training ground for many local pros. The Zayante Carbon is the ultimate marriage of lightness, stiffness and versatility.
