Aerodynamics: With extensive testing in CFD and in our Wind Tunnel, aerodynamics were at the forefront of the Porpero 4 development. We too the aerodynamic leading edge from the S-Works Evade 3 and pulled it directly into the Propero 4 - which helped it to be four watts, or 15 seconds over 40km faster than our S-works Prevail 3.

Ventilation: Drawing inspiration form our world renowned S-Works Prevail 3, our goal was not merely to replicate but to elevate. Ventilation became a focal point in our quest for a well balanced, aerodynamic and ventilated helmet. We incorporated the rear end design language of the S-Works Prevail 3 and introduced small 2mm offset micro channels that create turbulence in the airflow throughout the helmet to help create a continuous, refreshing flow of air.

Attention to Detail: Beyond just aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. We went the extra mile by incorporating cutting-edge technologies from our S-Works level helmets, like MIPS technology for confidence, and a fit system designed to deliver all-day comfort. The Propero 4 doesn't just meet expectations
