The Free Aero Race 4 Bib Short is Castelli's top race short, the result of meticulous evolution, comfortable even if you never pin on a number.

The original Free Aero Race Bib Short was first introduced over a decade ago and has logged literally millions of kilometers under the backsides of pro riders and has been the best-selling short in the Castelli retail collection. Over this time the short has undergone numerous updates and improvements in the never-ending quest to create Castelli's best short. While the basic concept of a minimalist workhorse pro-level comfortable race short remains, every single fabric, component, stitch, and construction method has been updated and improved over time.

The fourth major generation of the short features the updated Progetto X2 Air Seamless seat pad. This pad separates a soft, stretchy skin care layer that moves with your body from a generously padded cushioning layer that replicates the form of your saddle. Eight-hour rides are no problem.

Of course the fabrics are premium, made to Castelli's specifications by Italy's best fabric suppliers. The Forza fabric on the inner leg features 38% Lycra® content for perfect fit, while the Vortex fabric on the side panels is dimpled for aerodynamics. And it's held in place by the latest iteration of the seamless flat Giro leg gripper.

Engineered for aerodynamics and WorldTour racing performance. The careful choice of fabrics and components and the obsessive attention to detail make this bib short supremely comfortable for everyday riding and racing alike.

Castelli Sizing: Many Castelli products are designed with a European race-fit. It is not uncommon to size up one or two sizes for the right fit.

Note: All measurements are provided by the manufacturer and may vary depending on how measurements are acquired. Castelli instructs that for best results measurements be taken over underwear. Castelli recommends sizing up if measurements fall between sizes for a better fit.
