Cervelo S5 - Sram Red AXS

Notes from the builder

The new S5 has reduced drag by 65 grams, and increased the frame’s surface area while still reducing overall weight. The deeper frame sections maximize the shapes allowed by the UCI. Meanwhile the iconic V-stem has been further refined and a new fork designed to simplify the entire front end.

Wider wheels and tires are faster aerodynamically, and more comfortable to boot. S5 comes specced with 28mm tires but has clearance for up to a 34mm (measured) tire. The frame is optimized to complement the wider Reserve 52/63 turbulent aero wheels. In addition to the handling benefits, this saves over 5 watts compared to the previous Reserve wheelset.

The UCI’s new regulations on aerodynamic design allowed Cervelo additional room to deepen their aero profiles and squeeze 65 more grams of drag performance out of what is already the fastest aero bike on the market. You’ll notice a deeper head tube and BB area, and more aggressive shaping on the trailing edges of the tubes. Since the new S5 is only compatible with electronic shifting, Cervelo was able to tidy the dropout a bit, and update the shaping all over the bike.

Cervelo has improved the comfort of the handlebar, and tweaked the shape to get a perfectly flat bar-to-hood transition. They now use a two-bolt interface that allows for infinite tilt adjustments between 0 and 5 degrees.

About the Cervelo S5

The fastest bike of the modern aera. The S5 has one job—get to the line before everyone else. Under the likes of Wout van Aert, Marianne Vos, and Christophe LaPorte, the new model has already proven itself as a tool without equal. In the 2022 Tour de France, this bike propelled Wout to the highest ever Points Classification score of the modern era. At 480, Wout was some 194 points ahead of his nearest rival—tangible proof that Cervélo keeps delivering aerodynamic gains to our World Tour athletes.

 

The new S5 has reduced drag by 65 grams, and increased the frame’s surface area while still reducing overall weight. The deeper frame sections maximize the shapes allowed by the UCI. Meanwhile the iconic V-stem has been further refined and a new fork designed to simplify the entire front end. What’s more, a ground-breaking new wheel design concept has been co-developed with Reserve to increase stability and reduce drag in turbulent aero conditions.
