Racing Without Goggles Is a Compromise You Should Not Have to Make
Every cyclist who has raced or trained at speed knows the problem. 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.
The Yumaj YM-01 Aero TT Cycling Helmet with Goggles 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.
The Aerodynamic Advantage of an Integrated System
The 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.
For 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.
EPS + PC Construction — Ultralight and More Protective
The 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.
Together, 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.
CE Certified — Safety You Can Trust
The 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.
One Size, Universal Fit — 55–61cm
The 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.
Available in White and Black
The 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.
