The S5 is a sport-wide benchmark for speed and aerodynamic efficiency—with the race results to back it up.

The new S5 is 6.3 Watts faster than its predecessor. These gains are realized primarily at the front end of the bike, but the integration of the asymmetric profiles of the seat tube and rear wheel are a significant source as well. Cervélo has long been the aerodynamic leader in the peloton, and we’re confident that the new S5 is at least 5 Watts faster than the bikes of our competitors.
HB19 uses our “Plus-Four” concept, meaning the dimension at the hoods is 4cm narrower than in the drops (e.g. 38cm/42cm). This approach helps riders maintain a more aero body position while their hands are on the hoods, and provides stability in the drops for descending and sprinting. All bar sizes are UCI-legal, even in light of the most recent regulations change.
Despite an increase in surface area, the new S5 is 124 grams lighter than its predecessor. While the increase in fork and head tube depth added weight, we optimized the layup and hardware to make the system lighter.
