PROPERO 4 DARK NAVY METALLIC

DETAILS

AERODINÁMICA

With thorough testing in CFD and in our Win Tunnel, the aerodynamics were at the forefront of the development of Propero 4. We take the aerodynamic vanguard of the helmet to create a faster helmet. We take the aerodynamic front of the S-Works Evade 3 and attach it directly to Propero 4, which contributed to four watts, or 15 seconds in 40 km, faster than our S-Works Prevail 3.

VENTILATION

Inspiring in our world-renowned S-Works Prevail 3, our goal was not simply to reproduce it, but to take a further leap. Ventilation became a central point in our search for a well balanced, aerodynamic and ventilated helmet. We incorporate the back of Prevail 3 and introduce small 2 mm displaced microchannels that create turbulences in the airflow across the hull to help create a continuous and refreshing airflow.
