{"product_id":"propero-4","title":"Propero 4","description":"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. Every detail of the Propero 4 was created with the equation for speed in mind: Aerodynamics + Ventilation + Lightweight = Fast.\n\nWith extensive testing in CFD and in the Win Tunnel, aerodynamics were at the forefront of Propero 4 development. The aerodynamic leading edge from the S-Works Evade 3 was incorporated directly into the Propero 4, helping it to be four watts, or 15 seconds over 40km, faster than the S-Works Prevail 3.\n\nDrawing inspiration from the world-renowned S-Works Prevail 3, the goal was not merely to replicate but to elevate ventilation. Small 2mm offset micro-channels were introduced to create turbulence in the airflow throughout the helmet, helping to create a continuous, refreshing flow of air.\n\nBeyond aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. Cutting-edge technologies from S-Works level helmets were incorporated, including MIPS technology for confidence and a fit system designed to deliver all-day comfort.\n\n\u003cdiv data-section-type=\"hero-banner\" data-theme=\"white\" data-align-h=\"left\" data-align-v=\"center\" data-text-align=\"left\" data-content-max-width=\"250\"\u003e\r\n\u003ch3\u003ePropero 4\u003c\/h3\u003e\r\n\u003cimg src=\"https:\/\/assets.specialized.com\/i\/specialized\/ROAD_0916_2025_Propero-hero-2_desktop_16-25?fmt=auto\u0026amp;w=1200\u0026amp;q=80\" alt=\"Propero 4\" style=\"width:100%;height:auto;\"\u003e\r\n\u003c\/div\u003e\r\n\r\n\u003cdiv data-section-type=\"hero-banner\" data-theme=\"white\" data-align-h=\"left\" data-align-v=\"center\" data-text-align=\"left\" data-content-max-width=\"350\"\u003e\r\n\u003ch3\u003eInspired by the Best to Inspire Your Best\u003c\/h3\u003e\r\n\u003cp\u003eThe Propero 4 takes its DNA from our world-renowned S-Works Evade 3 and S-Works Prevail 3.
