Cervelo Framesets | S5 (2023)

The S5 prioritizes aerodynamic performance and stiffness, making it a platform preferred by the fastest sprinters in the world. You've no doubt noticed the now-iconic V-Stem. We optimized that shape to deliver the best possible performance in the wind, hid the cables inside, and made enough bar/stem/stack options to fit just about anyone. It'll clear 28mm tires, too so you can eke out even more aero advantage.

Cockpit
Improvement In pursuit of speed, everyone wants to try a different position, a longer stem, and a more aggressive fit. The updated Cervelo S5 makes installation and alteration easier. All the necessary spacers come with the bike, and there’s only one bolt length, instead of the previous stack-specific bolt spec. The handlebars attach more simply and have a 5-degree rotation to dial in your fit. Reducing all that complexity made the system 53g lighter, too. Cervelo improved the comfort of the handlebar and tweaked the shape to get a perfect bar-to-hood transition. In place of the shims on the previous S5 handlebar, Cervelo used a two-bolt interface that allows for infinite tilt adjustments between 0 and 5 degrees. 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 Cervelo will keep the 400mm long, 25mm offset post in stock for those looking for a more extreme fit.

Enhancements
The UCI’s new regulations on aerodynamic design allowed us some additional room to deepen the aero profiles and squeeze a little more 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.

Tire Clearance
Wider wheels and tires are faster aerodynamically, and more comfortable to boot. S5 has clearance for up to a 34mm (measured) tire and is optimized around the new, wider Reserve wheels, which are wrapped in 28mm tires. These wheels, developed under Turbulent Aero protocols, save a little over 5 watts.
