CASCO SPECIALIZED PROPERO 4

The Specialized Propero 4 helmet is born to offer high-level performance at an accessible price, combining the aerodynamics of the S-Works Evade 3 with the ventilation of the S-Works Prevail 3. The result is a fast, light, and comfortable helmet, designed according to the formula Aerodynamics + Ventilation + Lightness = Speed.

During development, aerodynamics was the starting point. Through CFD testing and wind tunnel trials, the profile inspired by the Evade 3 saves up to 4 watts, equivalent to approximately 15 seconds over a 40 km distance. A tangible difference for those seeking real performance on the road.

Ventilation derives directly from the S-Works Prevail 3 project. The large rear vents and internal 2 mm micro-channels create controlled turbulence, ensuring a continuous and refreshing airflow even during the most intense efforts.

The Propero 4 also integrates MIPS C-Solution technology for enhanced protection from rotational impacts and has achieved the top 5-star rating in the independent Virginia Tech® Helmet Rating™ tests. The FS3 adjustment system with an adjustable occipital base ensures a precise and personalized fit, compatible with eyewear use.
