Castelli Aero Race S bibshort 2025
Developed to meet the needs of high performance cyclists
From training rides close to home to the toughest bike races in the world, the Free Aero Race S Bibshort has been developed to meet the needs of high performance cyclists. When pedalling, it is essential that the bibshorts provide maximum comfort. The ‘Forza2 Stretch’ fabric adheres to the body without constricting it, guaranteeing freedom of movement with every pedal stroke. The bib straps are light and essential, but at the same time supportive, and are elasticated and breathable to offer high comfort. Silicone grips in the leg bottoms keep the shorts in the desired position. Naturally, Castelli has used the Progetto X2 Air Seamless pad for your comfort, even on the most intense training days.
In the modern world of high performance cycling, aerodynamics has quickly become one of the most important factors. Thanks to countless hours in the wind tunnel, Castelli has optimised the shorts to give you a 3% reduction in CdA, making the Free Aero Race Bibshort the fastest ever. This means that every watt you produce can be used to make you go faster.
