The new Cervélo S5 has revolutionized the aero road segment – again. It combines many incremental improvements across the frame to deliver one huge improvement to you: more speed. The model that BikeRadar calls “spectacular in terms of raw aggression and savage speed” now offers increased stiffness, race-ready geometry and improved ride quality to produce our fastest road bike ever.

The S5 perfects aerodynamic performance advantage with no compromise in weight — no small challenge given the high standards of the previous-generation S5. We also succeeded in significantly increasing torsional stiffness, a key factor in handling, to permit a more aggressive riding position. Our emphasis on systems engineering and structural efficiency maximizes stiffness while minimizing weight, and we’ve worked to perfect new manufacturing techniques to achieve tighter tolerances and improved compaction.


The new S5 Ultegra offers the same handling as our classic road R Series, but the frame size and fit has been adjusted to achieve a more aerodynamic riding position. 



Aerodynamics - Out-of-the-box speed means that all facets of the bike — components included — maximize aero advantage. Our Dropped Downtube and Shielding Seatstays are designed to minimize aero drag at precise locations on the frame using a systems approach. Cervélo’s new All-Carbon Aero Handlebar saves 4.4 Watts over a standard round bar, and is compatible with standard 31.8mm stems.


Stiffness -The new S5 offers a 6% increase in bottom bracket stiffness, giving you a high degree of connection to the road and a feel of efficiency with each pedal stroke. A 35% increase in headtube torsional stiffness and 17% increase in lateral fork stiffness offer increased confidence in cornering and overall handling.

Weight -You’ve probably never relished the climbs on an aero bike before. An aero bike that also offers category-leading lightweight performance is rare, but the S5 delivers. Our lightweight engineering refuses to compromise the airfoil shapes that give the S Series its distinctive design — and more distinctive performance — all without adding unnecessary weight.
