2026 Cervélo S5 Ultegra Di2 Unisex Road Bike, Five Black - FREE Shimano Dura-Ace SPD-SL pedals valued at $399.00!

The Cervélo 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.

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 they are confident that the new S5 is at least 5 Watts faster than the bikes of the competition.

One-Piece Handlebar/Stem
HB19 uses the “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, Cervélo optimized the layup and hardware to make the system lighter.

Reserve 57|64 Wheelset 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.
