Specialized S-Works Rapide Seatpost
Aero Efficiency. Lightweight Comfort. Race-Ready Performance.
The Specialized S-Works Rapide Seatpost is designed to help riders save valuable watts without compromising comfort. Developed using Specialized's Moving Leg Mannequin aerodynamic testing, it targets one of the highest airflow areas on a road bike—the seatpost. The result is a deeper, more aerodynamic profile with reduced frontal area that improves airflow while maintaining the compliance needed for long days in the saddle.
Constructed from premium FACT carbon, the S-Works Rapide Seatpost combines lightweight performance with controlled flex for a smooth ride. Precision saddle hardware allows quick, accurate adjustments, making it easy to dial in your riding position.
