The S-Works Rapide Post is a premium aerodynamic carbon seatpost engineered to reduce drag, improve airflow and maintain all-day ride comfort on high-performance road and gravel bikes. Designed using Specialized’s Moving Leg Mannequin testing, the Rapide Post targets one of the bike’s most important aero zones, where pedalling motion drives high-speed air directly onto the seatpost.
