The Free Aero Race short has been engineered as our premier race short. Our first Free Aero Race debuted in 2007 and has undergone continuous improvement as we develop new fabrics and construction methods and respond to feedback from our professional teams. We designed the Free Aero Race to be fast by concentrating on helping you get the most out of your body and by optimizing aerodynamics. The other main goal in this short is comfort, because the pros will be riding 30,000 km per year, and a four-hour ride isn’t even considered long. While the Free Aero Race short has been engineered for top-level racing, all its features make it an ideal short for whatever your cycling challenge.

Muscle Support and Speed
In re-engineering the Free we took a look at blood flow, providing just the right muscle support without constricting. The revolutionary Giro Air leg band provides more stretch and distributes the compression over a larger area. The body of the short uses 30% Spandex for excellent return.
We also looked at aerodynamics, optimizing boundary-layer airflow with the Giro Air leg band and the dimples on the side fabric. The wind tunnel says it saves 10 watts at 50 km/h, but you’ll probably want to go even faster because your aero advantage will only increase.
-
Confort and Fit
The best race short must be supremely comfortable. The new fabrics are all softer than the outgoing fabrics, especially the new softer surface fabric on the updated Progetto X2 Air seatpad. The innovative double V construction on the front keeps everything in place without compressing your stomach. And we’ve engineered a new Carré yoke that makes the straps lie perfectly flat.
But the most important part of comfort is fit. As one of our pro testers said, “These shorts fit perfectly. They don’t move around. Everything is just right.”
Every product is unique, just like you. If you're looking for a product that fits the mold of your life, the Castelli Free Aero Race 4 Bibshort - Black is for you.
