{"product_id":"specialized-propero-4-helmet","title":"Specialized Propero 4 Helmet","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, 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.\u003cbr\u003e\u003cbr\u003eAERODYNAMICS: With extensive testing in CFD and 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 and 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.\u003cbr\u003e\u003cbr\u003eVENTILATION: 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, and ventilated helmet. We incorporated the rear-end design language of the S-Works Prevail 3 and introduced small 2mm offset micro-channels that create turbulence in the airflow throughout the helmet to help create a continuous, refreshing flow of air.\u003cbr\u003e\u003cbr\u003eATTENTION TO DETAIL: Beyond just aerodynamics and 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, and a fit system designed to deliver all-day comfort. The Propero 4 doesn't just meet expectations; it redefines them. 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.\u003cbr\u003e\u003cbr\u003ePropero 4 earned the highest 5-Star Virginia Tech- Helmet Rating from internationally renowned Virginia Polytechnic Institute and State University.\u003cbr\u003e\u003cbr\u003eFS3 Fit System \u0026amp; Occipital Base Adjustment optimizes comfort by personalizing fit to individual head shape, and helmet angle can be adjusted for compatibility with glasses.\u003cbr\u003e\u003cbr\u003eAdjustable Tri-Fix web splitter combined with thin 10mm webbing for increased comfort.\u003cbr\u003e\u003cbr\u003eDedicated sunglass storage maintains a secure fit and keeps eyewear out of the way when needed.\u003cbr\u003e\u003cbr\u003eMicro Channeling \u0026amp; large rear-end vents for increased ventilation.\u003cbr\u003e\u003cbr\u003eS-Works Evade 3 front-end design language for enhanced Aerodynamics.\u003cbr\u003e\u003cbr\u003ePrecision, full-wrap polycarbonate shell for increased durability and premium finish.","brand":"Specialized","offers":[{"title":"Black \/ SMALL","offer_id":43857603723377,"sku":"FP_117939","price":239.99,"currency_code":"AUD","in_stock":true},{"title":"Black \/ MEDIUM","offer_id":43857603756145,"sku":"FP_117940","price":239.99,"currency_code":"AUD","in_stock":true},{"title":"Black \/ LARGE","offer_id":43857603788913,"sku":"FP_117941","price":239.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4704\/4721\/files\/MediumProduct_JIOZLNproper_919917_ccf88b67-4485-401c-a07a-f3df5086eef4.jpg?v=1785742519","url":"https:\/\/pedalheads.com.au\/products\/specialized-propero-4-helmet","provider":"Pedalheads ","version":"1.0","type":"link"}
