Cervelo S5 Ultegra Di2 Road Bike 2027 The Cervelo S5 Ultegra Di2 Road Bike is a masterclass in modern aerodynamic engineering, built explicitly for cyclists who refuse to compromise on raw speed and efficiency. Every aspect of this machine is sculpted to cheat the wind, featuring an all-carbon frame with TrueAero tube profiles and a striking integrated bayonet fork design that seamlessly slices through the air. By treating the frame, fork, and the innovative carbon one-piece cockpit as a unified aerodynamic system, this bike minimizes drag and maximizes your power output. Whether you are contesting a local criterium sprint, hunting solo breakaways, or simply looking to shatter your personal records on flat and rolling terrain, this bike turns your effort into pure, unadulterated velocity. Uncompromising Componentry and Precise Electronic Shifting At the heart of this high-performance build is the Shimano Ultegra Di2 12-speed electronic drivetrain, delivering lightning-fast, dependable gear changes even under heavy sprinting loads. The mid-compact chainrings paired with a wide-range cassette ensure you have the perfect cadence for both high-speed flats and challenging climbs, while the integrated dual-sided 4iiii Precision Pro power meter provides the accurate, real-time data required to optimize your training and pacing. Control is just as critical as speed, which is why the bike features hydraulic disc brakes with premium Centerlock rotors, offering predictable, fade-free stopping power in all weather conditions so you can corner with absolute confidence. Elite Wheelset and Tubeless Comfort for the Modern Road To fully unlock the potential of this aero frameset, it comes equipped with a staggered Reserve carbon wheelset spinning on legendary DT Swiss 240 hubs, a combination that balances crosswind stability in the front with maximum aerodynamic depth in the rear. These tubeless-compatible rims are paired with wide Vittoria Corsa Pro tires, providing a supple ride quality, lower rolling resistance, and exceptional cornering grip that redefines how a race bike should feel. Complete with a titanium-railed Selle Italia saddle and integrated computer mounts, this meticulously curated build is fully optimized to deliver an elite racing experience straight out of the box.
