Specialized launches new aero helmet, the Propero 4

On Tuesday, Tuesday launched a new aero helmet, the Propero 4. Although the helmet is meant to save you watts, that doesn’t mean Specialized has forgotten about proper ventilation.


The Propero is inspired by the S-Works Evade 3 and S-Works Prevail 3. You’ve probably seen those helmets on some of the best cyclists of the world like Lotte Kopecky, Demi Vollering, Remco Evenepoel, and Primož Roglič.

Specialized took some of the aero engineering from the S-Works Evade 3 and applied it to the Propero 4. The company claims that after wind tunnel testing, the Propero 4 four watts faster than the S-Works Prevail 3.


Although being fast is key, it’s also key to have good ventilation. Specialized took some of the data from the S-Works Prevail 3 using Computational Fluid Dynamics (CFD). The rear-end vents are optimized for airflow to keep cool while being fast.

To keep your head cool, Specialized has introduced something called “Micro Channelling.

The tech is inspired…by a tumble dryer. “Just as your clothes spin around, ensuring every fiber gets fully dry, MicroChanneling ensures that all the air within your helmet is working to constantly pull in cool air and expel hot air, creating a cooler ride,” Specialized said.

For rotational impact company, the helmet uses Mips Evolve Core, and has a 5-star Virginia Tech safety rating.

The helmet manages to be lightweight, coming in at 290 g for a size medium.
