Introducing the new Propero 4 helmet - the aerodynamics of the S-Works Evade 3 combined with the extraordinary ventilation of the S-Works Prevail 3, plus the comfort and reliability of all Specialized helmets, and the 5-star rating from the Virginia Tech Institute ®. Every detail of the Propero 4 was designed with the equation of Aerodynamics + Ventilation + Lightness = Speed ​​in mind.

AERODYNAMICS: In the development of the Propero 4, aerodynamics was the starting point, and to this end we carried out extensive CFD and in-house wind tunnel tests. With the profile inspired by the S-Works Evade 3 we already gain 4 watts, or 15 seconds over a distance of 40km.

VENTILATION: Taking inspiration from the S-Works Prevail 3 helmet we achieved our goals in terms of quality. We have incorporated the rear vents of the S-Works Prevail 3, and have introduced 2mm micro-channels that create turbulence in the airflow through the helmet, thus creating a continuous and refreshing passage of air.

ATTENTION TO DETAIL : In addition to aerodynamics and ventilation, the Propero 4 is characterized by meticulous attention to detail. We have applied cutting-edge technologies such as MIPS and a sealing system designed for comfort. The Propero 4 goes beyond expectations.
