CASTELLI Free Aero Race S Bib Shorts
Unleash your full potential on the road with the CASTELLI Free Aero Race S Bib Shorts, the definitive choice for cyclists who refuse to compromise between all-day comfort and outright speed. Engineered for peak performance, these men´s bib shorts represent the culmination of years of pro-level feedback and relentless aerodynamic testing. They are designed not just for race day, but for every ride where you demand the best from your equipment and yourself. The result is a short that feels as incredible on your longest training epics as it does when you´re sprinting for the line.
Experience a tangible competitive edge thanks to the revolutionary aero-optimized Forza2 Stretch fabric. This advanced, high-compression synthetic material provides exceptional muscle support to reduce fatigue while offering a remarkable degree of stretch for complete freedom of movement. Its primary function, however, is to cheat the wind. Through extensive wind tunnel development, the fabric and construction deliver a proven 3% decrease in CdA (Coefficient of Drag Area), allowing you to ride faster with the same power output. This is a measurable advantage that translates directly to performance.
At the core of the bib´s legendary comfort is the iconic Progetto X2 Air Seamless seat pad. Considered the gold standard for long-distance support, this chamois features a buttery-soft, seamless top layer that moves with your skin to eliminate chafing and a multi-density foam layer that provides targeted cushioning exactly where you need it. It’s the ultimate solution for comfort, even on your longest and most demanding rides. The upper construction complements this focus on comfort, featuring minimalist, lie-flat bib straps that you´ll barely notice, and a breathable mesh back panel that significantly improves airflow to keep you cooler when the intensity rises.
The fit is perfected with premium silicone leg grippers that ensure the short leg endings stay securely in place without digging in or constricting movement, maintaining a clean, aerodynamic profile from hip to knee. Practicality is also built-in, with a convenient back pocket ideal for stashing a gel, a key, or even a race radio. For those long, sunny days in the saddle, the short fabric provides a crucial layer of 50+ UPF protection, shielding your skin from harmful UV rays.
