Propero 4

Delivery Icon

We deliver! Just say when and how.

Meet the all-new Propero 4 helmet—it brings the aero advantages of the S-Works Evade 3 together with the ventilation of S-Works Prevail 3, all with the comfort and confidence Specialized helmets are famous for, earning the highest 5-Star Virginia Tech® helmet rating. Every detail of the Propero 4 was created with our equation for speed in mind. Aerodynamics + Ventilation + Lightweight = Fast.

AERODYNAMICS: With extensive testing in CFD and in our Win Tunnel, aerodynamics were at the forefront of the Propero 4 development. We took the aerodynamic leading edge from the S-Works Evade 3 and pulled it directly into the Propero 4—which helped it to be four watts, or 15 seconds over 40km, faster than our S-Works Prevail 3.

VENTILATION: Drawing inspiration from our world-renowned S-Works Prevail 3, our goal was not merely to replicate but to elevate. Ventilation became a focal point in our quest for a well-balanced, aerodynamic, and ventilated helmet. We incorporated the rear-end design language of the S-Works Prevail 3 and introduced small 2mm offset micro-channels that create turbulence in the airflow throughout the helmet to help create a continuous, refreshing flow of air.

ATTENTION TO DETAIL: Beyond just aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. We went the extra mile by incorporating cutting-edge technologies from our S-Works level helmets, like MIPS technology for confidence, and a fit system designed to deliver all-day comfort. The Propero 4 doesn't just meet expectations

Great helmet

It was time for a new helmet. Fits great. No hot weather riding, yet, so can’t give feedback on venting.

Well vented and perfect fit. Fits me much better than POC, which are tight on the sides. Sleek looking too.
