Introducing the revolutionary Specialized Propero 4 Helmet, merging the aerodynamic prowess of the S-Works Evade 3 with the exceptional ventilation of the S-Works Prevail 3. Engineered for ultimate comfort and confidence, it boasts a coveted 5-Star Virginia Tech® helmet rating from the prestigious Virginia Polytechnic Institute and State University. Designed with our formula for speed in mind—Aerodynamics + Ventilation + Lightweight = Fast—the Propero 4 excels in every aspect. From aerodynamics to ventilation to lightweight construction, this high-performance race helmet caters to riders of all levels, from novices to seasoned KOM/QOM chasers.
Departing from its predecessors, the Propero 4 draws inspiration from the renowned S-Works Evade 3 and S-Works Prevail 3 helmets, worn by cycling luminaries such as Demi Vollering and Remco Evenpoel. Now, with the Propero 4, we bring the technology of champions within reach of every rider, enabling anyone to experience exhilarating speed.
Aerodynamics is central to speed optimization, and the Propero 4 inherits cutting-edge aerodynamic engineering from the S-Works Evade 3. Leveraging computational fluid dynamics (CFD) and rigorous testing in our Win Tunnel, we refined the Propero 4's design to perfection. Our tests reveal that the Propero 4 outperforms the S-Works Prevail 3 by four watts, translating to a staggering 15-second advantage over 40km at an average speed of 45 kph.
