Castelli Aero Race 8 Jersey - Posidonia 2026

Official IG CYCLING Posidonia 2026 (Posidonia Tour) Charity Race Jersey

This collectible cycling jersey is the official kit for the IG CYCLING Posidonia 2026 charity race (Posidonia Tour). Based on the advanced Castelli Aero Race 8.0 model, it incorporates WorldTour expertise to offer unparalleled aerodynamic performance. The placement of fabrics and seams has been optimized through Computational Fluid Dynamics (CFD), ensuring the rider moves with the least possible wind resistance.

Drawing on more than a decade of innovation and knowledge in making professional riders faster, the Aero Race 8 Jersey is the result of using the most modern methods and fabrics to create the fastest jersey ever made. Dressing for speed is one of the best ways to get faster, since 80% of the drag on a cyclist comes from the body. The sleeve construction uses CFD engineering for optimal seam placement, while the engineered ribbed shoulder fabric provides a CdA savings of up to 6% over previous aero jerseys. The rest of the jersey is designed for maximum comfort with smooth, stretchy body fabric, bonded sleeve endings, and a silicone waist elastic to support loaded pockets.
