Specialized Propero 4 Helmet in Beige

Meet the all-new propero 4 helmetit 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. 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 4which 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, it redefines them. For helmets sold in the u.S. And canada: complies with u.S. Cpsc safety standard for bicycle helmets for persons age 5 and older
