Smoke Visor for Uvex Race 8 TT Helmet - One size

Triathlon is not just about watts and willpower – it’s also about equipment that can help you optimize every part of the race. A triathlon bike helmet is just such a piece of equipment. It is designed with one clear purpose: to minimize drag and maximize your speed, without compromising on comfort and ventilation. At Transition Zone, we sell triathlon helmets from Rudy Project, Uvex, MET, Sweet Protection and Giro – all brands with strong roots in the world of performance.

Unlike a traditional road helmet, a triathlon helmet is typically more aerodynamically shaped, with a smoother surface, integrated visor and optimised airflow. The design helps reduce turbulence around the head and the transition to the back – a small detail that makes a big difference over long distances. It is especially in time trials and non-drafting triathlons that the shape and structure of the helmet have a major impact on your average speed. Even an improvement of a few seconds per 10 km can be decisive in the overall result.

But it's not just aerodynamics that matter. Comfort is just as important. A good triathlon helmet should be lightweight, easy to put on and take off in the transition zone, and stay in place even under high intensity and hot conditions. Modern tri helmets take all of these elements into account – and you'll quickly notice the difference when you've found the right model.

A good triathlon helmet balances aerodynamics, comfort and functionality – and it is this balance that sets it apart from ordinary cycling helmets. Most tri helmets are developed in a wind tunnel and tested by professional athletes, which means that even small details like ventilation channels, visor shape and chin strap placement are thought out down to the smallest millimeter.

A key feature of many triathlon helmets is the integrated visor, which not only improves aerodynamics but also protects against sun, rain and insects. It eliminates the need for sunglasses and ensures clear vision even when you’re lying in an aero position for hours. Many helmets have magnetic or hinged visors, making it easy to manage at speed – or when you’re under time pressure in T1 or T2.

Ventilation is another important factor. Previous generations of aero helmets were known to be hot and a bit claustrophobic, but today's tri helmets have integrated air channels and advanced materials that ensure you can keep your head cool - even in 30 degree heat. Brands like Rudy Project and MET in particular have developed solutions where the helmet maintains its aerodynamic advantage without feeling like a sauna on your head.

Finally, fit and weight play a big role. A triathlon helmet should be light and fit snugly without squeezing. Adjustment systems are typically more precise than on regular helmets, and the best models allow micro-adjustments both horizontally and vertically. It’s important that the helmet neither slides backwards in an aero position nor squeezes so much that it bothers you on the bike. It should feel like a natural extension of your setup – helping you perform, not getting in the way.

At Transition Zone you will find a carefully selected range of triathlon helmets from Rudy Project, Uvex, MET, Sweet Protection and Giro – five manufacturers who all have proven experience in developing helmets for competition use. We only select helmets that meet our requirements for fit, performance and safety. Whether you are new to the sport or training specifically for Ironman, we will help you find the right helmet for your level and needs.

When choosing a triathlon helmet, it's not just about aerodynamics on paper - it's about the overall experience. How easy is it to change? How does it fit on your head? Is the ventilation sufficient for your particular training conditions? We recommend that you try the helmet physically in the store in Aarhus, or contact us for personal advice if you're shopping online. With the right tri helmet, you can gain free speed, increase comfort and get an important mental boost when you roll out of the transition zone.

Whether you prioritize low weight, an integrated visor or the most aerodynamic profile, we have the helmet that suits you. And once you've found the right one – all you have to do is step in and keep your cool.
