AERO PRO W JERSEY
THE FIRST AERODYNAMIC JERSEY PROJECT WE CALLED SPLIT SECOND
When Castelli developed the first aerodynamic jersey for road cycling back in 2006, everyone thought we were crazy. At that time, aerodynamics was only used in time trials. Performance clothing meant breathability management and you could win the Tour de France with a loose jersey that was little more than a polyester t-shirt. Even our aerodynamics experts expected limited benefits, which is why we called the Split Second jersey. Exactly then as now, we already thought that even a small advantage was worth pursuing. In the end, the benefits were substantial and we completely revolutionized the look of the pros as a group. | Now we have arrived at the sixth version of our aero 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 air flows in an aerodynamic position, influencing the choice of fabric and the placement of seams. It also benefits from feedback from Team INEOS Grenadiers riders, considering we have worked hard to make the jersey comfortable during their long hours of training and racing in all 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 ...

WHAT IT IS
