New model available at your official Cervélo, Elevate Bikeshop in Charmey Aerodynamics, again and always The new S5 is 6.3 watts faster than its predecessor. These gains come primarily from the front of the bike, but the integration of the asymmetrical profiles of the seat tube and rear wheel also contributes significantly. Cervélo has long been the leader in aerodynamics in the peloton, and we are confident that the new S5 is at least 5 watts faster than our competitors' bikes. Not just faster. Lighter too. Despite a larger surface area, the new S5 is 124 grams lighter than its predecessor. Although the increased depth of the fork and head tube has added weight, we have optimized the layering and components to lighten the entire system. Reserve 57|64 designed for the S5: The new Reserve 57|64 wheelset has been co-developed by Reserve and Cervélo, specifically for the new S5. The asymmetry of the rear wheel matches that of the seat tube, ensuring smooth airflow throughout. This new wheelset is 3 watts faster than the 52|63 wheels, while maintaining the same weight.
