Cycling and Triathlon Helmets — How to Choose the Right One?

The helmet is one of the most important pieces of equipment for triathletes and cyclists. Beyond safety, it plays a key role in aerodynamics and can save several watts over a bike course. At Triathlonstore, we offer a selection of road, aero, and time trial helmets suitable for all levels and distances.

Road Helmet or Aero Helmet for Triathlon?

The aero helmet (or time trial helmet) is designed to minimize aerodynamic drag at high speeds. It is particularly suitable for long-distance triathlons (70.3, Ironman) where an aero position is maintained for extended periods. The road helmet offers more ventilation and comfort, ideal for training and short triathlons.

Which Helmet Brands to Choose for Triathlon?

Kask, POC, and Giro are the market leaders. Kask is favored by professionals for its aerodynamics and comfort. POC excels in safety and ventilation. Giro offers versatile models suitable for all budgets.

Frequently Asked Questions about Cycling and Triathlon Helmets

Which Aero Helmet to Choose for an Ironman?

For an Ironman, opt for an aero helmet with good ventilation for long hours of racing. The Kask Bambino and POC Tempor are two highly popular choices among long-distance triathletes for their balance of aerodynamics and comfort.

Does an Aero Helmet Really Save Time in Triathlon?

Yes — according to aerodynamic tests, an aero helmet can save between 10 and 30 watts compared to a classic road helmet depending on speed and position. In an Ironman, this can represent several minutes of difference.

Should You Try on Your Helmet Before Buying It?

It is highly recommended, especially for aero helmets — aerodynamic gains vary depending on each athlete's morphology and position. Our in-store experts in Paris and Nice can advise you and help you find the most suitable model for your profile.

What is the Difference Between a Cycling Helmet and a Triathlon Helmet?

A triathlon helmet is generally more aerodynamic than a classic road helmet, with a profiled shape that reduces drag. Some models include a visor to avoid wearing separate glasses. Road helmets offer more ventilation for long rides and hot days.
