What counts on the racecourse is outright speed so we use the Cervelo S5 Road Frameset for every marginal gain while creating our dream build. Made from an all-carbon material while including the handlebar stem fork and seat post in the same frame creates a hyper-aero bike that's as comfortable on the road as it is on the podium. Cervelo uses advanced design practices to create an aero machine that's stiff where we want it to be while being comfortable when we need it. The Cervelo S5 is smartly designed with 28mm tire clearance proven to roll faster over a variety of terrain than thinner tired options. This frame ships without stem spacers. If we're building this up for you we'll be in touch to get fit info so we can install the necessary spacers. If you are building this yourself and require spacers please contact a gearhead.
