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.
The new S5 and R5 feature advanced, one-piece bar/stem combinations that make both bike and rider faster. However, we know that achieving a perfect fit is a critical component to not just speed, but comfort on the bike. As part of our development of the new bikes, we made a number of additional stem length/bar width combinations to make sure all riders can get as close to their ideal fit as possible.
Any rider that purchases a new S5 or R5 will be able to request an additional bar/stem in a different size at no extra charge. This request must be made via the Authorized Cervélo retailer where the bike was purchased, and must be made within the first 60 days of ownership. These new stem/bars will be provided by Cervélo free of charge, but any labor costs or cost of parts that may be required for removing and installing the bars will be the responsibility of the rider.

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.
