The wind at 40 km\/h makes your eyes water. Dust, insects, and road debris become genuine hazards. UV exposure over long rides causes eye fatigue that compounds with physical fatigue. And the standard solution — a separate pair of cycling glasses or goggles — adds complexity, adds cost, and creates the aerodynamic gap between helmet and eyewear that generates turbulence and drag.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eYumaj YM-01 Aero TT Cycling Helmet with Goggles\u003c\/strong\u003e eliminates this problem entirely. By integrating the goggle system directly into the helmet design, it removes the gap, removes the complexity, and removes the need to manage two separate pieces of eyewear equipment. You put on the helmet, the goggles are already there, and you ride — faster, more comfortably, and with complete eye protection from the first pedal stroke to the last.\u003c\/p\u003e\u003ch2\u003eThe Aerodynamic Advantage of an Integrated System\u003c\/h2\u003e\u003cp\u003eThe gap between a standard helmet and a separate pair of glasses or goggles is one of the most significant sources of aerodynamic turbulence on a cyclist's head. Air enters the gap, creates a turbulent wake, and adds drag that is measurable at race speeds. An integrated goggle system eliminates this gap entirely, creating a smooth, continuous surface from the helmet shell to the eye protection — reducing drag and improving the aerodynamic efficiency of the entire head-and-helmet system.\u003c\/p\u003e\u003cp\u003eFor time trial riders, triathletes, and road racers where every second counts, this is not a marginal gain. It is a meaningful aerodynamic advantage that requires no additional fitness, no additional training, and no additional effort.\u003c\/p\u003e\u003ch2\u003eEPS + PC Construction — Ultralight and More Protective\u003c\/h2\u003e\u003cp\u003eThe YM-01 uses a combination of EPS (Expanded Polystyrene) and PC (Polycarbonate) in its construction. EPS provides the primary impact absorption — the foam that compresses and deforms in a controlled way during an impact, absorbing and distributing energy before it reaches the skull. PC provides the outer shell — a harder, more abrasion-resistant material that protects the EPS foam from surface damage and provides the smooth, aerodynamic exterior surface.\u003c\/p\u003e\u003cp\u003eTogether, these materials create a helmet that is simultaneously lighter and more protective than single-material alternatives. The thickened EPS construction provides enhanced impact protection. The PC shell provides durability and aerodynamic consistency. And the combined weight of approximately 355g reflects the additional protection that the thickened construction provides — a worthwhile trade-off for riders who prioritise safety alongside performance.\u003c\/p\u003e\u003ch2\u003eCE Certified — Safety You Can Trust\u003c\/h2\u003e\u003cp\u003eThe CE certification confirms that this helmet has been independently tested and meets European safety standards for cycling helmets. For any rider who takes their safety seriously, the CE mark is the assurance that the protection this helmet provides is real, verified, and compliant with the standards that European regulators have determined are necessary to protect cyclists in the event of an impact.\u003c\/p\u003e\u003ch2\u003eOne Size, Universal Fit — 55–61cm\u003c\/h2\u003e\u003cp\u003eThe YM-01 fits head circumferences from 55 to 61 cm — the range that covers the majority of adult cyclists. The adjustable retention system allows you to dial in the fit precisely within this range, ensuring the helmet sits securely and comfortably regardless of where your head circumference falls within the size range.\u003c\/p\u003e\u003ch2\u003eAvailable in White and Black\u003c\/h2\u003e\u003cp\u003eThe YM-01 is available in White and Black — two colourways that work across any kit combination and any riding context, from training rides to race day.\u003c\/p\u003e\u003ch2\u003eAliExpress Standard Sizing Guide (Cycling Helmets)\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eOne Size:\u003c\/strong\u003e Head circumference 55–61 cm\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eMeasure at the widest point of your head, approximately 2.5 cm above the eyebrows.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e Yumaj\u003cbr\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e YM-01\u003cbr\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e EPS + PC (Ultralight, High-Density)\u003cbr\u003e\u003cstrong\u003eConstruction:\u003c\/strong\u003e Integrally-Moulded\u003cbr\u003e\u003cstrong\u003eCertification:\u003c\/strong\u003e CE\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 355g\u003cbr\u003e\u003cstrong\u003eAir Vents:\u003c\/strong\u003e \u0026lt;8\u003cbr\u003e\u003cstrong\u003eSize:\u003c\/strong\u003e 55–61 cm (One Size)\u003cbr\u003e\u003cstrong\u003ePacking:\u003c\/strong\u003e With Goggles\u003cbr\u003e\u003cstrong\u003eColours:\u003c\/strong\u003e White, Black\u003cbr\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Aero TT \/ Road \/ MTB \/ Triathlon\u003cbr\u003e\u003cstrong\u003eGender:\u003c\/strong\u003e Unisex Adults\u003cbr\u003e\u003cstrong\u003eHigh-Concern Chemicals:\u003c\/strong\u003e None\u003cbr\u003e\u003cstrong\u003eOrigin:\u003c\/strong\u003e Mainland China\u003c\/p\u003e","brand":"Elanique","offers":[{"title":"grey 1lens \/ 55-61cm","offer_id":53356510445911,"sku":"14:193#grey 1lens;5:872#55-61cm","price":156.06,"currency_code":"USD","in_stock":true},{"title":"white 1lens \/ 55-61cm","offer_id":53356510478679,"sku":"14:200004889#white 1lens;5:872#55-61cm","price":156.61,"currency_code":"USD","in_stock":true},{"title":"grey 3lens \/ 55-61cm","offer_id":53356510511447,"sku":"14:200002984#grey 3lens;5:872#55-61cm","price":165.91,"currency_code":"USD","in_stock":true},{"title":"white 3lens \/ 55-61cm","offer_id":53356510544215,"sku":"14:173#white 3lens;5:872#55-61cm","price":165.27,"currency_code":"USD","in_stock":true},{"title":"white blue 3lens \/ 55-61cm","offer_id":53356510576983,"sku":"14:100018786#white blue 3lens;5:872#55-61cm","price":200.55,"currency_code":"USD","in_stock":true},{"title":"ink grey 1lens \/ 55-61cm","offer_id":53356510609751,"sku":"14:200000195#ink grey 1lens;5:872#55-61cm","price":168.21,"currency_code":"USD","in_stock":true},{"title":"white blue 1lens \/ 55-61cm","offer_id":53356510642519,"sku":"14:365458#white blue 1lens;5:872#55-61cm","price":168.21,"currency_code":"USD","in_stock":true},{"title":"ink grey 3lens \/ 55-61cm","offer_id":53356510675287,"sku":"14:200006157#ink grey 3lens;5:872#55-61cm","price":179.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/8463\/0103\/files\/H95cdc65bf3fe431698d037fc028197e1s.webp?v=1779306021","url":"https:\/\/elanique.shop\/fr\/products\/yumaj-ym-01-aero-tt-cycling-helmet-with-goggles-road-mtb-triathlon","provider":"Elanique","version":"1.0","type":"link"}
