The S5 has only one mission: to get to the line before everyone else. Under the leadership of Wout van Aert, Marianne Vos and Christophe LaPorte, it has already proven to be an unrivaled tool. At the 2022 Tour de France, this bike propelled Wout to the highest points standings score in the modern era. Out of 480 points available, Wout overtook his closest rival to 194 points behind him—tangible proof that the Cervélo company continues to provide aerodynamic gains for our World Tour athletes.

The new S5 features deeper frame sections to maximize UCI-allowed shapes, a new fork design that helps simplify the entire front end, and increased wheel/tire clearance that accommodates the new Reserve 52/63 wheelset, which we co-developed to deliver an even faster bike.

V IS FOR VELOCITY

In pursuit of speed, everyone wants to try different positions to find their most aggressive fit. The S5's iconic V-stem not only inspires confident handling at high speeds, it's now also remarkably simple to dial in your perfect set-up. All the necessary spacers come with the bike, and there’s now only one bolt length, reducing complexity and making the system 53g lighter in the process.

FRAME ENHANCEMENTS

The UCI’s new regulations on aerodynamic design allowed us some additional room to deepen our 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, we were able to tidy the dropout a bit, and update the shaping all over the bike.

TIRE CLEARANCE

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.

HANDLEBAR REFINEMENT

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

KEEPING IT SIMPLE

Bike fitters at every level are moving away from longer-offset seat posts, and the new S5 comes stock with a 15mm offset post on most sizes (vs 25mm offset on outgoing S5). The old seat posts are forward-compatible, and we’ll keep the 400mm-long, 25mm offset post in stock for those looking for a more extreme fit.
