Propero 4

Meet the new Propero 4 helmetit brings the aerodynamic advantages of the S-Works Evade 3 along with the ventilation of the S-Works Prevail 3, all with the comfort and confidence Specialized helmets are famous for, earning the highest 5-star rating from Virginia Tech. Every detail of the Propero 4 was created with our speed equation in mind. Aerodynamics Ventilation Lightness = Speed.

– AERODYNAMICS:

With extensive CFD and Win Tunnel testing, aerodynamics were at the forefront of Propero 4s development. We used the aerodynamic edge of the helmet to create a faster helmet. We took the aerodynamic front of the S-Works Evade 3 and molded it directly into the Propero 4, making it four watts, or 15 seconds over 40 km, faster than our S-Works Prevail 3.

– VENTILATION:

Inspired by our globally known S-Works Prevail 3, our goal was not simply to replicate it, but to go further. Ventilation became a focal point in our pursuit of a well-balanced, aerodynamic, and ventilated helmet. We incorporated the back of the Prevail 3 and introduced small offset microchannels of 2 mm that create air turbulence throughout the helmet to help generate a continuous, cooling airflow.
