{"product_id":"specialized-propero-4-black","title":"Specialized Propero 4 Black","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.\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.","brand":"Specialized","offers":[{"title":"M","offer_id":57291782488445,"sku":"60124-1703","price":189.0,"currency_code":"EUR","in_stock":true},{"title":"S","offer_id":57291783438717,"sku":"60124-1702","price":190.0,"currency_code":"EUR","in_stock":true},{"title":"L","offer_id":57291785929085,"sku":"60124-1704","price":189.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0921\/2775\/6669\/files\/artPic_public_L_3421544.jpg?v=1761830724","url":"https:\/\/kaptein.cc\/products\/specialized-propero-4-black","provider":"Kaptein - The Complete Cycling Experience","version":"1.0","type":"link"}
