What Our Gearhead® Experts Are Saying:

"The aero advantage these bibshorts provide is no joke. The Forza2 fabric is snug but comfortable, and the Progetto X2 chamois keeps me comfortable on long rides. They feel great during hard efforts and keep everything in place even when I’m out of the saddle."

The Free Aero Race S Bibshort is a premium choice for riders who demand aerodynamic efficiency and superior comfort.

The Progetto X2 Air Seamless chamois delivers top-tier support with multi-density foam and a soft, skin-care layer for long hours in the saddle. Lightweight stripe mesh bib straps enhance airflow and eliminate unnecessary bulk, while silicone leg grippers keep the bibshort securely in place for consistent performance.

With a back pocket for race radio storage and UPF 50+ protection, the Free Aero Race S Bibshort is purpose-built for high-speed efforts and endurance rides alike. Whether you're racing to the podium or tackling century rides, these bibshorts help us perform at our best.
