Specialized Propero 4 helmet - Beige

Here is the new Specialized Propero 4 helmet - the aerodynamics of the S-Works Evade 3 combined with the extraordinary ventilation of the S-Works Prevail 3, and additionally, the comfort and reliability of all Specialized helmets, along with 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. In the development of the Propero 4, aerodynamics was the starting point, and to this end, Specialized conducted numerous CFD tests and wind tunnel testing. With a profile inspired by the S-Works Evade 3, it already gains 4 watts, which equals 15 seconds over a distance of 40km. Drawing inspiration from the S-Works Prevail 3 helmet, Specialized has achieved its quality goals by incorporating the rear vents of the S-Works Prevail 3 and introducing 2 mm micro-channels that create turbulence in the airflow through the helmet, thus creating a continuous and refreshing airflow. In addition to aerodynamics and ventilation, the Propero 4 is characterized by meticulous attention to detail, applying cutting-edge technologies such as MIPS and a retention system designed for comfort. The Propero 4 exceeds expectations.
