{"product_id":"casque-propero-4","title":"Propero 4 Helmet","description":"\u003cp\u003eMeet the all-new Propero 4 helmet - it brings the aerodynamic benefits of the S-Works Evade 3 along with the ventilation of the S-Works Prevail 3, all with the comfort and confidence that Specialized helmets are renowned for, achieving the highest 5-star Virginia Tech® Helmet Rating. Every detail of the Propero 4 was created with our speed equation in mind. Aerodynamics + Ventilation + Lightweight = Fast.\u003c\/p\u003e\n\u003cp\u003eAERODYNAMICS: Through extensive CFD and Win Tunnel testing, aerodynamics was at the forefront of the Propero 4’s development. We took the aerodynamic leading edge of the S-Works Evade 3 and pulled it straight into the Propero 4 - helping it be four watts, or 15 seconds over 40km, faster than our S-Works Prevail 3.\u003c\/p\u003e\n\u003cp\u003eVENTILATION: Taking cues from our world-renowned S-Works Prevail 3, our goal was not to simply replicate but to elevate. Ventilation became a focal point in our quest for a well-balanced, aero-and-ventilated helmet. We incorporated the S-Works Prevail 3’s rear-end design language and introduced small 2mm offset micro-channels that create turbulence in the airflow throughout the helmet to help create continuous, refreshing airflow.\u003c\/p\u003e\n\u003cp\u003eATTENTION TO DETAIL: Beyond aerodynamics and ventilation, the Propero 4 represents meticulous attention to detail. We went the extra mile by integrating the cutting-edge technologies from our S-Works level helmets, like MIPS for confidence, and a fit system designed to deliver all-day comfort. The Propero 4 doesn't just meet expectations\u003c\/p\u003e\n\u003cp\u003eMips Evolve Solution is a low-friction layer that allows a 10 to 15mm sliding motion in all directions. Studies indicate that this reduces some of the rotational forces transmitted to the brain during angled impacts.\u003c\/p\u003e\n\u003cp\u003ePropero 4 earned the highest 5-star Virginia Tech® Helmet Rating from the internationally renowned Virginia Polytechnic Institute and State University.\u003c\/p\u003e\n\u003cp\u003eFS3 fit system and occipital base adjustment optimizes comfort by personalizing fit to individual head shape, and helmet angle can be adjusted for eyewear compatibility.\u003c\/p\u003e\n\u003cp\u003eAdjustable Tri-Fix web splitter combined with a thin 10mm strap for added comfort.\u003c\/p\u003e\n\u003cp\u003eDedicated sunglasses storage keeps a secure fit and out of the way when needed.\u003c\/p\u003e\n\u003cp\u003eMicro-channeling and large rear vents for increased ventilation.\u003c\/p\u003e\n\u003cp\u003eS-Works Evade 3 front-end design language for improved aerodynamics.\u003c\/p\u003e\n\u003cp\u003ePrecision, full-wrap polycarbonate shell for increased durability and premium finish\u003c\/p\u003e","brand":"Specialized","offers":[{"title":"Small \/ Hyper Dove Grey","offer_id":47688719040666,"sku":"60124-0732","price":249.99,"currency_code":"CAD","in_stock":true},{"title":"Small \/ Noir","offer_id":47840053592218,"sku":"210000008318","price":249.99,"currency_code":"CAD","in_stock":true},{"title":"Medium \/ Hyper Dove Grey","offer_id":47840053756058,"sku":"210000008356","price":249.99,"currency_code":"CAD","in_stock":true},{"title":"Medium \/ Noir","offer_id":47840053723290,"sku":"210000008312","price":249.99,"currency_code":"CAD","in_stock":true},{"title":"Medium \/ Glacial","offer_id":47840053821594,"sku":"210000009512","price":249.99,"currency_code":"CAD","in_stock":true},{"title":"Large \/ Noir","offer_id":47840053657754,"sku":"210000008315","price":249.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0741\/1223\/7722\/files\/specialized-accessoires-small-hyper-dove-grey-casque-propero-4-36638078271642.webp?v=1776889961","url":"https:\/\/www.velovision.ca\/en\/products\/casque-propero-4","provider":"Vélo Vision","version":"1.0","type":"link"}
