WE CALLED THE FIRST AERODYNAMIC JERSEY PROJECT SPLIT SECOND
When castelli developed the first aerodynamic jersey for road cycling way back in 2006, everyone thought we were crazy. At that time, aerodynamics were only used in time trials. Performance clothing meant managing breathability, and you could win the Tour de France in a baggy jersey that was little more than a polyester t-shirt. Even our aerodynamicists expected limited benefits, which is why we called the jersey Split Second. Exactly then as now, we already thought it was worth chasing even a small advantage. In the end, the benefits were substantial and we completely revolutionized the look of professionals in groups. We have now reached the sixth version of our aerodynamic jersey. Each generation has become more aerodynamic and with a better fit. The Aero Race 6.0 benefits enormously from engineering studies through computer simulations of airflows in the aerodynamic position, influencing fabric choice and seam placement. It also benefits from feedback from Team Quickstep runners, considering we've worked hard to make the jersey comfortable during their long hours of training and racing in any possible weather conditions. The 6.0 is the most aerodynamic and most comfortable version ever made. But we are already working on version 6.1...
