Here is the new Propero 4 helmet - the aerodynamics of the S-Works Evade 3 combined with the extraordinary ventilation of the S-Works Prevail 3, and furthermore, the comfort and reliability of all Specialized helmets, and the 5-star rating from the Virginia Tech Institute®. Every detail of the Propero 4 has been 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 for this purpose, we conducted numerous CFD tests and in our wind tunnel. With the profile inspired by the S-Works Evade 3, we already gain 4 watts, which translates to 15 seconds over a distance of 40km.
VENTILATION: Taking inspiration from the S-Works Prevail 3 helmet, we have achieved our goals in terms of quality. We have incorporated the rear vents of the S-Works Prevail 3, and we have introduced 2 mm 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 exceeds expectations.
- Mips C-Solution Technology
- 'In the Virginia Tech® Helmet Rating™ scale of Virginia Polytechnic Institute and State University, the Propero 4 received 5 stars, the highest rating.'
