{"product_id":"casco-specialized-propero-4-nero-rosso","title":"Specialized Propero 4 helmet - Black red","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, and additionally, the comfort and reliability of all Specialized helmets, along with 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 the development of the Propero 4, aerodynamics was the starting point, and to this end, Specialized conducted numerous CFD tests and wind tunnel testing. With a profile inspired by the S-Works Evade 3, it already gains 4 watts, which equals 15 seconds over a distance of 40km. Drawing inspiration from the S-Works Prevail 3 helmet, Specialized has achieved its 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. In addition to aerodynamics and ventilation, the Propero 4 is characterized by 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 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 the individual head shape.\u003c\/li\u003e\n\u003cli\u003eThe helmet's position 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 integration 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\u003eVery durable polycarbonate shell with a premium finish.\u003c\/li\u003e\n\u003cli\u003eEN1078 certification.\u003c\/li\u003e\n\u003cli\u003eColor: Black red.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Specialized","offers":[{"title":"51-56 \/ Black","offer_id":52485438734682,"sku":"60126-1712","price":157.0,"currency_code":"EUR","in_stock":true},{"title":"55-59 \/ Black","offer_id":52453333762394,"sku":"60126-1713","price":157.0,"currency_code":"EUR","in_stock":false},{"title":"58-62 \/ Black","offer_id":52454117605722,"sku":"60126-1714","price":157.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/Casco-Specialized-Propero-4-Nero-rosso-All4cycling-0.webp?v=1760641654","url":"https:\/\/maisoncalyx.shop\/en\/products\/casco-specialized-propero-4-nero-rosso","provider":"All4cycling ","version":"1.0","type":"link"}
