{"product_id":"propero-4-aus-1000208598","title":"Propero 4","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. Every detail of the Propero 4 was created with our equation for speed in mind. Aerodynamics + Ventilation + Lightweight = Fast.  AERODYNAMICS: 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.  VENTILATION: 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.  ATTENTION 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.  For helmets sold in the U.S. and Canada: Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older. 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\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\u003e\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.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e","brand":"Specialized","offers":[{"title":"Dark Navy Metallic \/ M \/ Classic","offer_id":51000139284758,"sku":"60124-2723","price":300.0,"currency_code":"AUD","in_stock":true},{"title":"Dark Navy Metallic \/ S \/ Classic","offer_id":51000139317526,"sku":"60124-2722","price":300.0,"currency_code":"AUD","in_stock":true},{"title":"Dark Navy Metallic \/ L \/ Classic","offer_id":51000139350294,"sku":"60124-2724","price":300.0,"currency_code":"AUD","in_stock":false},{"title":"White \/ M \/ Classic","offer_id":51000139448598,"sku":"60124-2713","price":300.0,"currency_code":"AUD","in_stock":false},{"title":"White \/ S \/ Classic","offer_id":51000139415830,"sku":"60124-2712","price":300.0,"currency_code":"AUD","in_stock":true},{"title":"White \/ L \/ Classic","offer_id":51000139383062,"sku":"60124-2714","price":300.0,"currency_code":"AUD","in_stock":true},{"title":"Black \/ M \/ Classic","offer_id":51000139546902,"sku":"60124-2703","price":300.0,"currency_code":"AUD","in_stock":true},{"title":"Black \/ S \/ Classic","offer_id":51000139481366,"sku":"60124-2702","price":300.0,"currency_code":"AUD","in_stock":true},{"title":"Black \/ L \/ Classic","offer_id":51000139514134,"sku":"60124-2704","price":300.0,"currency_code":"AUD","in_stock":true},{"title":"Hyper Dove Grey \/ M \/ Classic","offer_id":51000139645206,"sku":"60124-2733","price":300.0,"currency_code":"AUD","in_stock":false},{"title":"Hyper Dove Grey \/ S \/ Classic","offer_id":51000139612438,"sku":"60124-2732","price":300.0,"currency_code":"AUD","in_stock":true},{"title":"Hyper Dove Grey \/ L \/ Classic","offer_id":51000139579670,"sku":"60124-2734","price":300.0,"currency_code":"AUD","in_stock":true},{"title":"Sandstone Metallic \/ M \/ Classic","offer_id":51000139710742,"sku":"60126-2703","price":300.0,"currency_code":"AUD","in_stock":true},{"title":"Sandstone Metallic \/ S \/ Classic","offer_id":51000139677974,"sku":"60126-2702","price":300.0,"currency_code":"AUD","in_stock":false},{"title":"Sandstone Metallic \/ L \/ Classic","offer_id":51000139743510,"sku":"60126-2704","price":300.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/4765\/0326\/files\/60124-172_HLMT_PROPERO-4-HLMT-CE-DEEPMARN-M_HERO-SQUARE.jpg?v=1769776563","url":"https:\/\/cbcycles.com.au\/products\/propero-4-aus-1000208598","provider":"CB Cycles Australind","version":"1.0","type":"link"}
