What Our Gearhead® Experts Are Saying:
"The Free Aero Race S Short isn’t just about aerodynamics—it’s the whole package. The Progetto X2 Air chamois ensures comfort during long miles, while the silicone grippers and Forza2 fabric make every ride faster and more efficient."
The Free Aero Race S Short is engineered for cyclists who demand top performance.

The silicone leg grippers provide a secure fit, eliminating distractions so we can focus entirely on the ride.
Comfort remains a priority thanks to the Progetto X2 Air Seamless Donna chamois, which is highly breathable and offers optimal padding for long days in the saddle. With UPF 50+ sun protection built in, the Free Aero Race S Short is perfect for tackling sunny circuits and endurance events alike. Whether we’re chasing PRs or crushing interval sessions, these shorts deliver the speed and support we need to perform at our best.
