Soudal/Quick-Step Free Aero Race S Bibshort - Men's

What Our Gearhead® Experts Are Saying:

"These bibs are all about efficiency and comfort. The Forza2 fabric hugs the legs for a compressive, aero fit while remaining breathable, and the Progetto X2 Air chamois eliminates pressure points on endurance rides. The silicone grippers keep them locked in place without squeezing too tight, and the mesh bib straps are so light I forget they’re there. It’s the perfect mix of race performance and everyday comfort."

The Free Aero Race S Bibshort is the pinnacle of race-level performance and long-distance comfort. Engineered with Castelli’s aero-optimized Forza2 Stretch fabric, these bibs provide a compressive, aerodynamic fit that enhances power transfer and reduces drag. The fabric’s 3% decrease in CdA means every watt we push goes further, whether we’re sprinting for the line or grinding through an all-day ride.

The Progetto X2 Air Seamless seat pad ensures unparalleled comfort, with multi-density foam and a seamless design that eliminates irritation. Silicone leg grippers keep the bibs perfectly positioned, while lightweight mesh bib straps enhance breathability for warm-weather rides. A back pocket offers added storage, and UPF 50+ protection helps shield from the sun’s harsh rays.

From high-speed racing to epic endurance days, the Free Aero Race S Bibshort is the ultimate companion for riders who demand the best in comfort, aerodynamics, and performance.
