Let me guess.

You either just bought a tri bike and now need to upgrade your helmet as well. (because a super fast bike with a beginner helmet just looks ridiculous).

Or you think you’ll just buy the helmet for aero gains on your road bike (but to be completely honest, the upgrade to a tri bike won’t take long either).

And you’re right because aero helmets are engineered to reduce wind resistance, potentially saving precious seconds or even minutes throughout a race. 

With numerous options on the market, selecting the best aero helmet can be tricky….but this is what I’m here for!

This review highlights the best aero helmets for triathlon, considering factors like aerodynamics, comfort, weight, safety features, and ventilation.

Why Aero Helmets Matter in Triathlon

In triathlon, where every second can count towards achieving a personal best or winning a podium place, the marginal gains offered by aero helmets can be significant.

Over the bike leg of a triathlon, which can be anywhere from 20 km in a sprint distance to 180 km in a full Ironman, the cumulative time savings from reduced drag can be substantial.

Many studies provide proof of this. Standard helmets impose a higher drag in comparison to an aero road helmet. 

Aero helmets also contribute to energy savings, allowing athletes to conserve energy for the running leg of the race.

Aero Road Helmet VS Standard Helmet VS Time Trial Helmet

The main difference between an aero bike helmet and a normal cycling helmet lies in the design focus:

• Aero Road Helmets: Designed primarily for speed, they feature a smoother surface and fewer vents, to minimize air resistance. They are ideal for races and time trials where aerodynamics is a priority over long-distance comfort. This is the middle ground between a standard road cycling helmet and a TT and triathlon helmet.
• Standard Road Helmets: These prioritize ventilation and comfort, featuring more vents and a design that promotes airflow over and around the head to keep riders cool over longer distances. While they are more versatile, they are not as aerodynamically efficient as aero-road helmets.
• Time Trial Helmets: Characterized by their distinctive shapes, often featuring a long tail to smooth airflow across the helmet and down the back of the rider, they’re engineered to minimize drag in a straight-line position. Strategic vent placements, internal channeling, and advanced materials work together to keep the rider cool while maintaining aerodynamic advantages. But these helmets are less about comfort and more about performance, specifically tailored for time trials and triathlon bike legs where every second counts. 

In any case, wearing a helmet is a must, at least at competitions, so you can decide if you want to wear an aero cycling helmet or just go with a regular one.

How an Aero Helmet Can Benefit You

• Time Savings: The most direct benefit is the potential reduction in time against the clock, which can be crucial in competitive settings.
• Energy Efficiency: By cutting through the air more effectively, you expend less energy battling wind resistance, potentially leaving more watts in reserve for later stages of the race.
• Safety and Comfort: Modern aero helmets also incorporate advanced safety features like MIPS (Multi-directional Impact Protection System), along with design considerations for fit and comfort, making them a smart choice for both performance and protection.

Frequently Asked Questions

Is an Aero Helmet Worth It?

Investing in an aero helmet is worth considering for any triathlete focused on improving performance. The primary advantage lies in its ability to reduce aerodynamic drag, which is a significant factor in the cycling portion of a triathlon.

By optimizing the shape and design to cut through the air more efficiently, aero helmets can offer tangible time savings, which could be crucial in a competitive race. 

Does an aero helmet make a difference?

An aero helmet stands out from traditional cycling helmets primarily due to its ability to minimize wind resistance.

By employing aerodynamic shapes and sometimes longer tails, these aero helmets can help streamline the way air passes over and around the helmet and rider. This reduces the drag.

This reduction in drag means that for the same power output, a rider can maintain higher speeds over distances, translating to improved race times and efficiency.

Does an aero helmet make you faster?

The helmet itself doesn’t increase your muscular power or endurance! Rather, it enhances your aerodynamics, so you can achieve higher speeds for the same physical output.

The bike leg of a triathlon is usually the largest part, so aerodynamic efficiency is crucial.

Riders may find that they can maintain higher average speeds with less perceived exertion with an aero helmet, thanks to the reduced drag. Therefore, while the helmet doesn’t boost your physical capabilities, it optimizes your performance

What are the aero helmet time savings in an Ironman race?

Savings can vary based on conditions and the athlete, but improvements of several minutes over the bike leg are not uncommon. The exact time savings depend on factors like the helmet’s design, the athlete’s aero position on the bike, and environmental conditions.
