Specialized S-Works Rapide FACT Carbon Seatpost

Specialized S-Works Rapide: the aero carbon seatpost designed to maximize performance

The Specialized S-Works Rapide seatpost was developed to offer the perfect balance between aerodynamics, lightness, and comfort, contributing to improving the overall performance of the bicycle. Designed through in-depth fluid dynamics studies and tests with mannequins equipped with movable legs, it has been optimized to reduce air resistance in areas where aerodynamic flow is most intense during pedaling.

The result is a FACT carbon seatpost capable of improving aerodynamic efficiency without sacrificing its ability to absorb vibrations, offering comfort even on the longest and most demanding rides.

Optimized Aerodynamics

During the development of the project, Specialized identified the seatpost as one of the elements most affected by the airflow generated by the cyclist's leg movement.

For this reason, the new S-Works Rapide adopts:

• an innovative D-profile;
• a reduced frontal surface;
• the thinnest section ever made by Specialized in this area;
• a deeper profile that promotes cleaner and more efficient airflow.

These features contribute to reducing aerodynamic drag and increasing the overall efficiency of the bicycle.

Uncompromising Comfort

The FACT carbon construction was designed to ensure controlled flexibility that improves comfort during long rides, while maintaining high levels of stiffness and strength.

The balance between vibration absorption and power transmission makes the seatpost ideal for both competitive use and intensive training.

Simple and Precise Adjustments

The saddle clamping hardware was manufactured with precision machining to offer:

• quick adjustments;
• high precision inclination;
• secure clamping;
• low weight.

This allows you to easily find the ideal saddle position and make any changes simply and quickly.
