The new Free Aero Race 4 Bibshort is the result of over a decade of partnerships with pro teams. Castelli has implemented miles of racing and riding experience into ensuring that the latest clothing is ready to meet the demands of professionals, and also that of performance-focused cyclists. As one of Castelli's best-selling bibshort for the professional rider and race-ready athlete alike, the latest iteration keeps everything loved about the Free Aero Bibshort and makes a few key improvements.
Minimal and Fast
A brand new bib construction is implemented for a minimalist fit, which has been combined with fabrics that boast better breathability. Featherweight, super-thin striped mesh aids in breathability. When the race turns up, the Free Aero Race 4 will lend to better temperature regulation than before.
New leg grippers lay flat, allowing stretch through all phases of the pedal stroke. Now with vertical silicone, the laser cut raw edges are staying right where they belong, from the beginning to the end of your ride. Receiving the updated Progetto X² Seamless seat insert reduces road vibrations while be extremely soft and comfortable.
