Castelli Free Aero Race S Bib Shorts - Paprika Red

Cycling Bib Shorts Castelli Free Aero Race S Kit – Aerodynamics and race-day comfort

The Castelli Free Aero Race S Kit bib shorts represent the evolution of competition bib shorts: a garment designed to offer maximum aerodynamics, extended comfort, and high-level performance. Developed to meet the demands of the most demanding cyclists, it is ideal for both intense training sessions and the toughest races.

Thanks to the Forza2 Stretch aerodynamic fabric, the bib shorts fit perfectly to the body without restrictions, ensuring freedom of movement and muscle support during pedaling. This innovative material, wind tunnel tested, allows for a 3% reduction in the aerodynamic drag coefficient CdA, improving efficiency and turning every watt produced into greater speed.

The minimalist striped mesh straps are lightweight, breathable, and elastic, designed to provide stability and temperature regulation without adding weight. The silicone grips on the leg hems keep the shorts perfectly in place even during the most intense efforts.

For long-distance comfort, Castelli has integrated the Progetto X2 Air Seamless chamois, one of the brand’s most advanced, designed to provide support and cushioning even on the longest rides and race days.

A practical detail designed for competitive cyclists is the rear pocket, useful for small items or race radio.
