{"product_id":"casco-specialized-propero-4-azzurro","title":"Specialized Propero 4 helmet - Light blue","description":"\u003cp\u003eHere is the new Specialized Propero 4 helmet - the aerodynamics of the S-Works Evade 3 combined with the extraordinary ventilation of the S-Works Prevail 3, as well as the comfort and reliability of all Specialized helmets, and the 5-star rating from the Virginia Tech Institute®. Every detail of the Propero 4 has been designed with the equation of Aerodynamics + Ventilation + Lightness = Speed in mind. In developing the Propero 4, aerodynamics was the starting point, and for this purpose, Specialized conducted numerous CFD tests and wind tunnel testing. With a profile inspired by the S-Works Evade 3, it gains 4 watts, which translates to 15 seconds over a distance of 40km. Drawing from the S-Works Prevail 3 helmet, Specialized has achieved quality goals by incorporating the rear vents of the S-Works Prevail 3, and introducing 2 mm micro-channels that create turbulence in the airflow through the helmet, thus creating a continuous and refreshing airflow. Besides aerodynamics and ventilation, the Propero 4 features meticulous attention to detail, applying cutting-edge technologies such as MIPS and a retention system designed for comfort. The Propero 4 exceeds expectations.\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMips C-Solution technology.\u003c\/li\u003e\n\u003cli\u003eOn the Virginia Tech® Helmet Rating™ scale from the Virginia Polytechnic Institute and State University, the Propero 4 received 5 stars, the highest rating..\u003c\/li\u003e\n\u003cli\u003eThe FS3 retention system and occipital base adjustment allow for fine-tuning to individual head shape.\u003c\/li\u003e\n\u003cli\u003eThe helmet's positioning angle can be adjusted for compatibility with glasses.\u003c\/li\u003e\n\u003cli\u003eTriFix strap system for optimal comfort.\u003c\/li\u003e\n\u003cli\u003eGlasses insertion capability.\u003c\/li\u003e\n\u003cli\u003eThin straps, 10mm wide.\u003c\/li\u003e\n\u003cli\u003eLarge rear vents and internal micro-channels for maximum ventilation.\u003c\/li\u003e\n\u003cli\u003eFront profile inspired by the S-Works Evade 3.\u003c\/li\u003e\n\u003cli\u003eHighly durable polycarbonate shell with premium finish.\u003c\/li\u003e\n\u003cli\u003eEN1078 certification.\u003c\/li\u003e\n\u003cli\u003eColor: Light blue (Glacial).\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Specialized","offers":[{"title":"51-56 \/ Blue","offer_id":49838591410522,"sku":"60125-1712","price":157.0,"currency_code":"EUR","in_stock":false},{"title":"55-59 \/ Blue","offer_id":49838704329050,"sku":"60125-1713","price":157.0,"currency_code":"EUR","in_stock":false},{"title":"58-62 \/ Blue","offer_id":49838579777882,"sku":"60125-1714","price":157.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/60125-171_HLMT_PROPERO-4-HLMT-CE-GCL_HERO-PDP.webp?v=1730881894","url":"https:\/\/www.all4cycling.com\/en\/products\/casco-specialized-propero-4-azzurro","provider":"All4cycling ","version":"1.0","type":"link"}
