Best Choice Castelli Free Aero Race 4 Bibshorts Black

The Castelli Free Aero Race 4 Bibshorts demonstrate a meticulous evolution. These are Castelli’s top race shorts, delivering excellent comfort. After over a decade in production, the Castelli Free Aero Race Bibshorts have logged literally millions of kilometers with sponsored pro riders. It’s no surprise that they have been the bestselling short in the Castelli retail collection. 

Over this time these shorts have undergone numerous updates and improvements in Castelli’s neverending quest to create the best short they can make. While the basic concept of a minimalist workhorse prolevel comfortable race short remains, every single fabric, component, stitch and construction method has been updated and improved over the years.

The Castelli Free Aero Race 4 Bibshorts feature 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. Even eighthour rides are no problem for these bibshorts.

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