The Cervelo S5 frameset rebuilds the front end of an already fast bike. Deeper fork legs, a redesigned head tube, and a one-piece carbon bar and stem route every cable internally and present a cleaner profile to the wind. The Bayonet fork and integrated cockpit work as a single aero system rather than assembled parts, so the gains compound rather than cancel each other out. The result is a carbon aero road frameset where fit and aerodynamics are solved together, not traded against each other. What Our Gearhead(R) Experts Are Saying:"The deepened fork legs and one-piece bar move the biggest aero gains to the front of the bike, where the wind hits hardest."Building up the S5 Frameset and want help dialing in the right spec Our Gearhead(R) Experts know this frame inside out.
