S5
PURE SPEED
The S5 is a sport-wide benchmark for speed and aerodynamic efficiency—with the race results to back it up. From Wout van Aert winning the Green Jersey by the biggest margin of victory in modern history, to Simon Yates riding himself into the maglia rosa, S5’s iconic V-stem and bayonet fork are a fixture at the front of the professional peloton. The new S5 builds on that legacy of speed by getting even faster.
The new bike is over 6 Watts faster than its predecessor, 124 grams lighter, and retains the handling, poise, and stability that riders everywhere love. The biggest changes are at the front of the bike, where the most significant aerodynamic performance comes from. The fork legs and head tube got quite a bit deeper, and the all-new, one-piece handlebar/stem builds on the original V-stem concept—and gets even faster.
Cervélo and Reserve co-developed the new Reserve 57|64 Turbulent Aero wheels specifically for use in the S5 frame, completing the aerodynamic system.

Aero Aero Aero
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.
One-Piece Handlebar/Stem
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.
Not just faster. Lighter, too.
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.
Reserve 57|64 Designed for S5:
The new Reserve 57|64 wheelset was co-developed by Reserve and Cervélo, and designed for use in the new S5. The rear wheel’s asymmetry matches the seat tube, ensuring air flows smoothly over both. The new wheelset is 3 Watts faster than the 52|63 wheels, and weighs the same.
ONE PEACE OF MIND
The new S5’s one-piece bar and stem is a big part of the bike’s increase in aerodynamic performance, but aerodynamic improvements are limited if the bike doesn’t fit you perfectly. We made nine different size combinations, and when you buy an S5, your Authorized Cervélo Retailer will help you get the right bar/stem combo, for no additional cost.

Frame Sizing
How do I determine what bike size I need?
The age-old question, isn’t it? There are many factors that go into bicycle sizing and fit, particularly for high-performance bikes. Without being able to measure you and see you on a bike, precise fit information is difficult to supply. It’s also not unusual for someone to be able to ride two different sizes depending on their goals, flexibility, and fit tolerance. That said, we have some fantastic retailers, and we’d encourage you to go start a conversation with them about what you want from your new bike. You can find the retailer closest to you on our Dealer Locator.
