Cervelo S5

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. The offset of the wheels perfectly matches the asymmetry of the S5 seat tube, and they tuck right into the wheel cut outs. This ensures that air flows smoothly over the entire bike, and Reserve’s Turbulent Aero approach makes them incredibly stable, even in crosswinds.

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.

HANDLEBAR SIZING: Get in touch with us with you Bike Fit data or by making an appointment in store to help determine the best size prior to purchase. Any rider who purchases a new S5 will be eligible to trade in their original equipment HB19 handlebar for one handlebar of a different size at no cost within the first 60 days of purchase.

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.
