Castelli Free Aero Race S Bib Shorts

Castelli Free Aero Race S Bib Shorts The Castelli Free Aero Race S Bib Shorts are their fastest and most comfortable race-focused shorts to date. They excel in the elbows-out, high-speed exhilaration of a surging peloton and the lung-bursting efforts of training. Castelli's Forza2 stretch fabric gives precise and supportive comfort, moving smoothly with every pedal stroke. Forza2 is also aero-optimised, with a claimed percentage reduction in CdA of 3%, letting you get up to and hold speed with ruthless efficiency.  The bib straps are minimal, with a lightweight and flexible construction that gives a barely-there feel and allows optimal breathability. Low-profile leg grippers ensure everything stays in place, letting you concentrate on race tactics and interval splits.  Progetto X2 Air seamless seat pad A pro-level seat pad engineered for maximum comfort. A plush and seamless skin-care layer feels super soft against your skin and reduces the chances of abrasion and irritation.
