When Castelli introduced the first aero jersey for road racing in 2006, many people thought it was a crazy idea, including some professional riders. At that time, aerodynamics were only used for time trials. Performance clothing focused on managing moisture, and it was believed that one could win the Tour de France wearing a loose jersey that was essentially a polyester T-shirt with pockets on the back. Despite skepticism, Castelli pressed on and named the jersey the Split Second. The gains turned out to be significant, revolutionizing the appearance of professional cycling.

Now in its seventh major revision, the aero jersey continues to show improvements. Through CFD analysis of wake flow in the riding position and feedback from pro riders, the jersey has been optimized for speed and comfort during long rides. For those crucial moments, wearing the Bolero SS base layer under the jersey can provide even greater aerodynamic advantages.
