Free Aero Race S men's bib shorts | Castelli

From your local training routes to the world's toughest cycling races, the Free Aero Race S Bib Shorts were developed to meet the demands of the performance cyclist. When you get on a bike, the first thing you expect from your bib shorts is comfort. The stretchy Forza2 fabric hugs your body without being too tight, allowing the fabric to move with you with every pedal stroke. The bib straps remain lightweight and minimalist while still providing good support, and are stretchy and breathable to ensure a high level of comfort. Silicone grippers at the bottom of the legs keep the shorts perfectly in place. And, of course, we've used our Progetto X2 Air Seamless chamois to keep you comfortable, even on the longest training days. In the modern world of performance cycling, aerodynamics has quickly become one of the most important components. After countless hours of wind tunnel testing, we've optimized the aerodynamics of the bib shorts to give you a 3% reduction in drag coefficient (CdA), making them the fastest Free Aero Race Bib Shorts we've ever created. This means all the energy you produce can be used to help you go faster.
