{"product_id":"specialized-propero-4-mips-helmet","title":"Specialized Propero 4 MIPS Helmet","description":"\u003cp\u003eMeet 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.\u003c\/p\u003e\u003cp\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.\u003c\/p\u003e\u003cp\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.\u003c\/p\u003e\u003cp\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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMips 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.\u003c\/li\u003e\n\u003cli\u003ePropero 4 earned the highest 5-Star Virginia Tech® Helmet Rating from internationally renowned Virginia Polytechnic Institute and State University.\u003c\/li\u003e\n\u003cli\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.\u003c\/li\u003e\n\u003cli\u003eAdjustable Tri-Fix web splitter combined with thin 10mm webbing for increased comfort.\u003c\/li\u003e\n\u003cli\u003eDedicated sunglass storage maintains a secure fit and keeps eyewear out of the way when needed.\u003c\/li\u003e\n\u003cli\u003eMicro Channeling \u0026amp; large rear-end vents for increased ventilation.\u003c\/li\u003e\n\u003cli\u003eS-Works Evade 3 front-end design language for enhanced Aerodynamics.\u003c\/li\u003e\n\u003cli\u003ePrecision, full-wrap polycarbonate shell for increased durability and premium finish.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Specialized","offers":[{"title":"Black \/ M","offer_id":47268857741566,"sku":"210000097942","price":229.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ L","offer_id":47268857774334,"sku":"210000097943","price":229.99,"currency_code":"USD","in_stock":true},{"title":"White \/ M","offer_id":47268857807102,"sku":"210000097944","price":229.99,"currency_code":"USD","in_stock":true},{"title":"White \/ L","offer_id":47268857839870,"sku":"210000097945","price":229.99,"currency_code":"USD","in_stock":true},{"title":"Hyper Dove Grey \/ M","offer_id":47268857872638,"sku":"210000097946","price":229.99,"currency_code":"USD","in_stock":true},{"title":"Hyper Dove Grey \/ L","offer_id":47268857905406,"sku":"210000097947","price":229.99,"currency_code":"USD","in_stock":true},{"title":"Glacial \/ S","offer_id":47268857938174,"sku":"210000097948","price":229.99,"currency_code":"USD","in_stock":true},{"title":"Glacial \/ M","offer_id":47268857970942,"sku":"210000097949","price":229.99,"currency_code":"USD","in_stock":true},{"title":"Black \/ S","offer_id":47271130136830,"sku":"210000097941","price":229.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0344\/4994\/8716\/files\/nlh2a19dgxetintlsga8.jpg?v=1779219436","url":"https:\/\/alpineeastdeals.com\/products\/specialized-propero-4-mips-helmet","provider":"Alpine East","version":"1.0","type":"link"}
