Why We Like The Free Aero Race 4 Limited Edition Bib Short

Designed to cheat the wind, the Free Aero Race 4 Limited Edition Bib Short as it's top-tier short for training and racing. We love it particularly for how well it handles the heat, allowing us to ride in the hottest weather. The Limited Edition designation pertains to the use of colors that distinguish it from the standard Frees. Comfort, aero benefits, and strikingly good looks, all in one package.


Inside the bib, the excellent Progetto X2 Air chamois has a seamless construction, four-way stretch, and impressive ventilation with its perforated foam layer. The Forza material of the legs offers just the right amount of compression to aid in recovery and prevent premature fatigue over rougher terrain. The Doppio V construction allows for excellent breathability without sacrificing support while the suspenders are mostly mesh and utilize lie-flat material on the shoulders. For the leg openings, Castelli trusts its Giro 4 mesh-like grippers to keep the hem in place.

Great Bib Shorts!? First Impressions

Familiarity:
I've used it once or twice and have initial impressions

Concerned when first put on, they seemed a snug fit (I typically wear Medium in shorts without any issues). Immediately noticed good fit of chamois. Love the texture of the fabrics. Thin and snug, tech feel in various panels, felt cool on a warm day. The chamois is as comfortable as any I own (and I own way too many including the latest Assos). All of this on my first 20+ mile ride in SoCal through the hills. Only initial concern is that the straps are light and may roll a little compared to more structured styles. I hesitate to mark these as "runs small" because they were so comfortable to ride in, so the tight fit seems intentional?
