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 & 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 & 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 & 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 & ventilated helmet. We incorporated the rear-end design language of the S-Works Prevail 3 & 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 & 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 & a fit system designed to deliver all-day comfort. The Propero 4 doesnt just meet expectations; it redefines them. For helmets sold in the U.S. & Canada: Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 & Older. Mips 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 & State University. FS3 Fit System & Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape & 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 & 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 & premium finish. ...
