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. This S-Version is spec'd with a simplified and economic set of our new LevaTime II rings with steel bolts.
