Cervelo S5 Frameset TVLAB Replica - 2026

Aerodynamics
The 2026 S5 boasts a 6.3-watt gain over the previous version. This increased performance is due to extensive work on the front of the frame, particularly on the fork legs and head tube, but also to the integration of asymmetric profiles on the seat tube and rear wheel. Cervélo estimates that this frame is at least 5 watts faster than its main competitors.

HB19 handlebar and aero position
The HB19 carbon one-piece cockpit incorporates the “Plus-Four” concept: the width at the hoods is 4 cm narrower than at the bottom of the handlebar, which helps reduce aerodynamic drag without compromising stability when descending or sprinting. All dimensions comply with the latest UCI regulations.

Weight reduction
Despite a larger frontal area, the S5 2026 frame boasts a weight reduction of 124 grams thanks to optimized carbon layup and adjustments to structural components.

Reserve 57|64 wheel compatibility
The S5 was developed in collaboration with Reserve to maximize the power of the 57|64 wheelset. The rear wheel's asymmetry follows the seat tube profile for smoother airflow and a 3-watt gain over the 52|63 wheels, without any added weight.
