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 sponsored 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 the best short we can make.
