Description
Meet the all-new Specialized Propero 4 MIPS Road 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 Specialized's 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. Specialized 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 the S-Works Prevail 3.VENTILATION: Drawing inspiration from their world-renowned S-Works Prevail 3, Specialized's goal was not merely to replicate but to elevate. Ventilation became a focal point in their quest for a well-balanced, aerodynamic, and ventilated helmet. They 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. Specialized went the extra mile by incorporating cutting-edge technologies from their 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.Specialized Propero 4 MIPS Road Helmet FeaturesMips Evolve Solution is a low-friction layer that allows a sliding motion of 10 to 15mm in all directions. Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts.Propero 4 earned the highest 5-Star Virginia Tech® Helmet Rating from internationally renowned Virginia Polytechnic Institute and State University.FS3 Fit System & Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape, and helmet angle can be adjusted for compatibility with glasses.Adjustable Tri-Fix web splitter combined with thin 10mm webbing for increased comfort.Dedicated sunglass storage maintains a secure fit and keeps eyewear out of the way when needed.Micro Channeling & large rear-end vents for increased ventilation.S-Works Evade 3 front-end design language for enhanced Aerodynamics.Precision, full-wrap polycarbonate shell for increased durability and premium finish.
