Engineered for aerodynamics and WorldTour racing performance, the Castelli Free Aero Race 4 short features a careful choice of fabrics and components with an obsessive attention to detail to make this bibshort supremely comfortable even when you don't pin on a number. 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 many sponsored pro riders and has been the best-seller throughout.
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. 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 Castelli's seamless flat Giro leg gripper. Please Note: Castelli use Italian sizing which is significantly smaller than the standard US equivalent, we recommend taking one size larger than your normal size.Please Note: Castelli use Italian sizing which is significantly smaller than the standard US equivalent, we recommend taking one size larger than your normal size.
