Specialized Propero 4 Helmet

Specialized Propero 4 road cycling helmet, white and fluorescent. Specialized reference: 60124-1734

Meet the new Propero 4 helmet - it 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 that Specialized helmets are famous for, earning the highest rating of 5 Virginia Tech® stars. Every detail of the Propero 4 was created with our speed equation in mind. Aerodynamics + Ventilation + Lightness = Speed.

AERODYNAMICS: With extensive testing in CFD and in our Win Tunnel, aerodynamics was at the forefront of the development of the Propero 4. We took the aerodynamic cutting edge of the helmet to create a faster helmet. We took the aerodynamic front end of the S-Works Evade 3 and molded it directly onto the Propero 4, which helped make it four watts, or 15 seconds to 40 km, faster than our S-Works Prevail 3.

VENTILATION: Inspired by our world-famous S-Works Prevail 3, our goal was not to simply reproduce it, but to take it one step further. Ventilation became a focal point in our search for a well-balanced, aerodynamic and ventilated helmet. We incorporated the rear of the Prevail 3 and introduced small 2mm offset microchannels that create airflow turbulence throughout the helmet to help create a continuous, cooling airflow.

Ventilation became the focus of our search for a well-balanced, aerodynamic and ventilated helmet.
