{"product_id":"2024-propero-4-helmet","title":"2024 | Propero 4","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. 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.\u003c\/p\u003e","brand":"Specialized","offers":[{"title":"Deep Marine Metallic \/ Small","offer_id":51411882082600,"sku":"SPE36980164S","price":250.0,"currency_code":"CAD","in_stock":true},{"title":"Deep Marine Metallic \/ Medium","offer_id":51411882115368,"sku":"SPE36215587M","price":250.0,"currency_code":"CAD","in_stock":false},{"title":"Deep Marine Metallic \/ Large","offer_id":51411882148136,"sku":"SPE36410197L","price":250.0,"currency_code":"CAD","in_stock":false},{"title":"Black \/ Large","offer_id":51411882180904,"sku":"SPE33222029L","price":250.0,"currency_code":"CAD","in_stock":true},{"title":"Black \/ Small","offer_id":51411882213672,"sku":"SPE33507428S","price":250.0,"currency_code":"CAD","in_stock":true},{"title":"Black \/ Medium","offer_id":51411882246440,"sku":"SPE33372376M","price":250.0,"currency_code":"CAD","in_stock":true},{"title":"Powder Indigo \/ Small","offer_id":51411882279208,"sku":"SPE37429213S","price":250.0,"currency_code":"CAD","in_stock":false},{"title":"Powder Indigo \/ Large","offer_id":51411882311976,"sku":"SPE37488719L","price":250.0,"currency_code":"CAD","in_stock":true},{"title":"Hyper Dove Grey \/ Medium","offer_id":51411882344744,"sku":"SPE39553926M","price":250.0,"currency_code":"CAD","in_stock":false},{"title":"Hyper Dove Grey \/ Large","offer_id":51411882377512,"sku":"SPE39230209L","price":250.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/8262\/3016\/files\/2024-Propero-401-1-The-BikeShop-Aug09.png?v=1771222958","url":"https:\/\/thebikeshop.com\/products\/2024-propero-4-helmet","provider":"The Bike Shop","version":"1.0","type":"link"}
