The Castelli AERO / Free Aero collection is designed for those who ride "like racers": aggressive position, high speeds, every watt counted. Here, the goal is singular: reduce aerodynamic drag without sacrificing comfort and stability in the saddle. It is the ideal line for competitive racers, advanced gran fondo riders, and tri/road racers seeking "race-fit" garments and WorldTour-level details: the Aero Race 8S brings next-generation aerodynamics with sleeves developed through CFD analysis and ribbed fabric on the shoulders for a CdA reduction of up to 6%; the Free Aero Race and Free Aero RC bib shorts focus on muscle support and long-distance comfort thanks to Forza2 fabrics and the Progetto X2 Air Seamless chamois, with a structure also optimized for aerodynamics (on the Free Aero Race: CdA -3%). To complete the kit, "speed-first" accessories: Aero Race shoe covers (aero, waterproof non-insulated, waterproof zip, 10–18°C), AeroRace Pro 20 socks with aerodynamic ribs and a 20 cm high cuff, and Rosso Corsa Pro gloves with a back made from the same aero fabric as the 8S and a palm in Dyneema® for superior protection.

Who it's for: those who do intense rides, criteriums/gran fondos, threshold training, and want a kit that transforms every watt into speed.
