TheSpecialized S-Works Rapide Seatpostfeatured here at Escapa is designed to reduce aerodynamic drag in areas of high airflow. Using our test dummy with movable legs, we discovered that pedaling directs high-speed air directly toward the seatpost, making it a critical aerodynamic surface. Its deeper profile—with a reduced frontal area and the thinnest section we’ve achieved in this area—provides cleaner airflow and improved aerodynamic performance, while our refined FACT carbon layup maintains balanced flexibility for optimal all-day comfort.
Features:
The D-shaped design and optimized layup construction deliver the most aerodynamic and comfortable seatpost.
The FACT carbon construction combines durability with comfort. The lightweight, precision-engineered seat clamps allow for quick, precise, and effortless adjustments.
Compatible with the Tarmac SL9, Crux 5, and Tarmac SL8.
