WALGUN Aero TT Time Trial Cycling Helmet with Lens – CE Certified Road & MTB

The Problem: Every Second Counts, and Your Helmet Is Costing You Time

In time trial and road racing, the margins are measured in seconds. The difference between a podium finish and a mid-pack result is often not fitness, not training, not even tactics — it's aerodynamics. The drag created by a non-aero helmet is not theoretical. It is measurable, consistent, and cumulative over the course of a race. Every minute you spend riding with a standard helmet is a minute you're giving away to riders who have made the aerodynamic choice. The WALGUN Aero TT Time Trial Cycling Helmet is that choice.

CE certified, EPS-constructed, and weighing just 285g, this is a helmet that takes the aerodynamic demands of time trial and road racing seriously — without the weight penalty that compromises climbing performance or the price point that puts professional-grade aero equipment out of reach for serious amateur riders.

Aero Shell Design: Engineered for Speed

The integrally-moulded EPS (Expanded Polystyrene) shell is the construction method that delivers both aerodynamic performance and impact protection in a single, unified structure. Unlike helmets with a separate outer shell bonded to an EPS liner, the integrally-moulded design creates a seamless surface that reduces drag and eliminates the structural weak points that can develop at the bond line between shell and liner.

The aero profile — elongated at the rear, smooth across the crown — is designed to reduce the frontal area presented to the wind and to channel airflow smoothly over and around the helmet rather than creating the turbulent wake that standard round helmets produce. At race speeds, this translates to a measurable reduction in aerodynamic drag and a corresponding improvement in speed for the same power output.

8–15 Air Vents: Aero Performance Without Overheating

The 8–15 air vents are the engineering compromise that makes this helmet genuinely usable in race conditions. Pure aero helmets with no ventilation are faster in a wind tunnel but can cause dangerous overheating in warm conditions or during high-intensity efforts. The ventilation channels on this helmet are positioned to maximise airflow across the head while minimising the aerodynamic penalty — giving you the cooling you need to maintain performance without sacrificing the speed advantage that an aero design provides.

Integrated Lens: Goggle-Free Racing

The integrated lens is the feature that makes this helmet a complete racing system rather than just a helmet. By incorporating the lens directly into the helmet design, it eliminates the need for separate goggles — reducing the total aerodynamic profile, eliminating the gap between helmet and eyewear that creates turbulence, and simplifying the pre-race setup. The lens is available in multiple tint options to suit different light conditions, from bright sunlight to overcast racing days.

CE Certified: Safety You Can Trust

The CE certification confirms that this helmet has been independently tested and meets the European safety standards for cycling helmets. In a market where uncertified helmets are common, the CE mark is the assurance that the protection this helmet provides has been verified by an independent testing authority rather than claimed by the manufacturer.

Size Guide

• M: 54–57 cm head circumference
• L: 57–61 cm head circumference

Measure your head circumference at the widest point (approximately 2.5 cm above the eyebrows). If between sizes, size up for comfort and a more secure fit.

For the Rider Who Takes Performance Seriously

The WALGUN Aero TT Helmet is for the rider who understands that equipment matters — who has done the training, put in the miles, and wants gear that doesn't limit what their fitness can achieve. At 285g, it won't slow you on the climbs. With CE certification, it won't compromise your safety. And with its aero profile and integrated lens, it won't give away the seconds that your training has earned.
