Product details

Designed to meet the demands of performance cyclists. Created for a fresh look on all your rides.

Whether for a training ride in your neighborhood or the toughest bike races in the world, the Free Aero Race S Bibshorts are engineered to meet the needs of performance cyclists. When you get on the saddle, the first thing you want from your bibshorts is high comfort. The Forza2 Stretch material shapes the body without constricting it and moves with you with every pedal stroke. The minimalist straps are lightweight yet provide support, are stretchy, and breathable for maximum comfort. The silicone anti-slip inserts at the leg openings ensure a good fit, just the way you like it. Of course, our Progetto X2 Air Seamless pad is included, providing comfort even on long training rides. In the world of modern cycling, aerodynamics has quickly become one of the most important performance aspects. After countless hours in the wind tunnel, we have optimized the bibshorts for a 3% lower drag, making them the fastest Free Aero Race Bibshorts we have ever designed. This way, every watt you generate can be used to make you ride even faster.
