Castelli Aero Race 8S 2026 Short Sleeve Jersey

Over a decade of innovation and experience in the world of speed. Our fastest jersey is even faster today.

In the world of high-performance cycling, we want to get more watts and more speed out of our equipment. Clothing specifically created for speed is the best way to go faster, because L80% of a cyclist's aerodynamic resistance is due to the body. With over a decade of innovation and experience making professional runners faster, the Aero Race 8S Jersey was created with the most modern methods and fabrics and has become our fastest jersey ever. The S stands for “speed”. The sleeve construction is engineered and CFD based for optimal seam placement. The engineered ribbed shoulder fabric has been specifically designed for maximum aerodynamic advantage at race speeds, with a CdA reduction of up to 6% compared to previous aero jerseys. The rest of the shirt is designed for maximum comfort. The smooth, stretchy main fabric allows for a perfect fit and optimal next-to-skin comfort. LThe elastic waist keeps the shirt in place and supports the three rear pockets when loaded. Aero Race 8S Jersey is the cutting-edge garment that transforms your watts into speed.
