Specialized S-Works Rapide FACT Carbon Seatpost

300mm | 15mm Offset | Satin Carbon | Aero D-Shape Design

The Specialized S-Works Rapide Seatpost is purpose-built for riders seeking every aerodynamic advantage without compromising comfort. Developed using Specialized's advanced Moving Leg Mannequin aerodynamic testing, the Rapide Post features a deeper D-shaped profile and optimized FACT carbon construction to reduce drag where airflow is greatest during pedaling.

Designed specifically for the latest generation of Specialized performance road bikes, the Rapide Post combines exceptional aerodynamics, lightweight construction, and refined compliance for maximum speed and all-day comfort.
