Castelli Free Aero Race 4 Bibshort Black

The Free Aero Race 4 Bibshort is Castelli’s top race short, which also means that it's insanely comfortable even if you never pin on a number. The original Free Aero Race Bibshort was first introduced over a decade ago and has logged literally millions of kilometers under the backsides of Castelli sponsored pro riders and has been the best-selling short both in the Castelli retail collection and in their Servizio Corse custom program. Over this time the short has undergone numerous updates and improvements in the never-ending quest to create the best short they can make. 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. Featuring 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.
