Mad Duck Custom Free Aero Race S Bibshort by Castelli

Built for speed. Ready for suffering. Styled for the flock.

The Mad Duck Custom Free Aero Race S Bibshort brings genuine WorldTour-level technology to our everyday rides—and those Tuesday nights that somehow turn into race day.

Castelli’s aero-optimized Forza2 Stretch fabric molds comfortably to the body, supporting your muscles without restricting your pedal stroke. Extensive wind-tunnel development gives this bib short a claimed 3% reduction in CdA, making it the fastest Free Aero Race bib Castelli has produced.

At the heart of the bib is Castelli’s premium Progetto X2 Air Seamless seat pad. Its soft, seamless skin-care layer reduces friction, while ventilated, multi-density cushioning provides support exactly where it is needed. Whether you’re attacking the fast group ride or settling into a long day in the saddle, it is designed to keep comfort from becoming the limiting factor.

Lightweight lie-flat straps and a breathable mesh back keep the upper body cool, while silicone leg grippers hold the raw-cut openings securely without unwanted movement. The main fabric also provides UPF 50+ protection, and a small rear pocket offers space for extra storage or a race radio—because looking professional is half the battle.

Finished in deep Mad Duck navy with crisp white graphics and a sharp pink leg stripe, these bibs are fast, distinctive and unmistakably ours.
