The Best Cycling Helmet for Triathlons

A helmet is a must-have accessory for any triathlete, and it’s equally important for your training sessions. With the availability of lightweight helmets with ample ventilation, there’s no reason to skip wearing one.

When it comes to triathlon bike racing, aerodynamics is a key factor, and our guide features a variety of fast helmets that not only provide comfort but also help to enhance your race performance by reducing your race time.

There’s also transition (T1) where you don’t want to lose time there putting on your helmet so we will cover the best helmets for speedy transitions.

Considerations When Chosing a Triathlon Cycling Helmets

At the end of the day the reason we wear a helmet when we cycle is for safety. Of the 700-plus bicycle deaths each year, approximately three-quarters are from head injuries. A 2016 study of more than 64,000 cyclists found that wearing a helmet can reduce the risk of fatal head injury by nearly 70 percent. When selecting a helmet for triathlon racing, there are several factors to consider:

  1. Aerodynamics – A helmet with a streamlined shape and a low profile will reduce drag and wind resistance, which is crucial in triathlon racing.
  2. Ventilation – Look for a helmet that provides sufficient airflow to keep you cool and comfortable during the race.
  3. Weight – A lightweight helmet will reduce the strain on your neck and shoulders and allow you to maintain a comfortable and efficient riding position.
  4. Fit and Comfort: The helmet should fit snugly and securely on your head without being too tight or uncomfortable. It’s essential to try on different helmets to find the perfect fit for your head shape.
  5. Safety Standards: Always choose a helmet that meets safety standards set by relevant authorities, such as CPSC, EN1078, or AS/NZS2063.
  6. Visor: Some helmets come with a detachable visor that can be helpful in reducing glare and protecting your eyes from the sun or rain. Consider whether this is a feature you need for your race.
  7. Transition Time: Look for helmets with easy-to-use straps and buckles that can be quickly adjusted and secured during transitions between race stages. Some helmets have magnetic clasps for super-fast transitions.

Helmet Race Rules

We have all seen professional triathletes getting unnecessary penalties in races because of helmet rule infringements. Do you remember Hayden Wilde at the Commonwealth games when he was battling Alex Yee for the top spot? They reached the final bend and Wilde, with a low five and fist bump, stopped at the penalty box. He got a 10-second penalty issued for unfastening his helmet before his bike was properly racked in T2. This lost him the race.

Quite simply, your helmet must be on your head and secured before you remove your bike from racking and remain that way until you return from the bike course and the bike is securely racked again.

Your helmet must be an approved ANSI Z90.4, SNELL B90, EN 1078 or equivalent standard and this can be checked by looking inside your helmet. Note that a CE mark is not an approved standard.

In your race pack you will probably have a race number which you need to stick on the front of your helmet so ensure you read your specific race rules.

Coaches Tip for Quick Transitions: Helmet

During your training you should practice T1 and T2 several times and when you have found your optimum set-up that works for you take a photo of it and replicated in transition on race day.

Your helmet must be fastened before you leave transition. So, it’s important to get it on, done up and secured as quickly as possible. Before the race, place it on the handlebars, with the cords opened and unlocked. Give yourself enough space in the helmet so it fits comfortably on your head without too much adjustment. This will help avoid any unnecessary time delays.

Practice putting it on and fastening it quickly several times during training so it’s second nature.

Different Types of Triathlon Helmets

One helmet does not fit all! There are a few different types of cycling helmets that you need to take into consideration when choosing the right one for you.

Road: Road helmets are the most common helmet that people wear when recreationally using their bike. The material used in these helmets is plastic and foam, which protects your head. Cyclists wear them to stay safe from bike or major car accidents.

Aero: Aero Helmets are good for those looking for smooth airflow when riding. In other words, using these helmets can effectively enable the air to flow over the top of the helmet and reduce drag. An aero road bike helmet is a hybrid between a road bike helmet and a TT helmet. It gives you all of the benefits of a TT helmet but without a long tail. 

An aero road helmet features an aerodynamic design that moves air up over the helmet. Traditional road bike helmets have multiple vents that channel the air through the helmet, also keeping you cool. The best aero road helmets will incorporate ventilation to keep you cool and still efficiently move air up and over the helmet.

TT: TT means “Time Trail” which can make it a great option for longer triathlons. TT helmets are more commonly used by elite cyclists and triathletes looking for every advantage to reduce drag and maximize speed. Their distinguishing feature is a long tail off the back of the helmet to aid in providing the least amount of wind resistance when a rider is in the aero position.

While you don’t need them in everyday training, you will want to seriously look at getting one for a time trial and or triathlon race formats where every second counts.

As with all triathlon kit you need to find the right helmet for your needs and budget. The decision will also depend on if you plan to do short course triathlon or long course triathlon like an IRONMAN. The following helmets will help you make your mind up.

GIRO has implemented a unique helmet design with TransformvAir technology, which helps with drag during cycling. The Transform Air technology provides advanced aerodynamics which is useful for both racing and training.

The helmet comes in three different standard sizes – small, medium, and large. This means the customer can find the correct fitting helmet based on Giro’s specifications in it’s sizing chart.

The lenses/shades are also replaceable so you can use their own shade in the helmet if you choose.

I personally own the Giro Vanquish and it’s been a great hemlet. The fit has been very comfrotable, but by far the best feature is the magenetic shades. Even on a cloudy day you can see perfectly so the shades keep the sunlight out while still allowing you to see clearly in darker conditions, which is super important for biking.

$224.95 at Specialized.com

This helmet Specialized designed with McLaren but enhanced by taking it back into the wind tunnel to make it even more slippery. The S-Works TT helmet has a longer tail than most, so it’s best for riders who have their TT position dialled and can tuck their head. Airflow is inside the shell is courtesy of the patented side ‘gill’ vents that move a surprising amount of air through the lid — not the breeziest helmet on the market, but it’s not sweltering either. 

The visor is removable, but it’s not a sophisticated system like the POC, Smith or Giro, with Specialized opting for clips instead of magnets.

Triathlon Helmet FAQ

Why do I need a specific helmet for triathlon racing?

Triathlon helmets are designed with aerodynamics, ventilation, and comfort in mind, which are essential for the unique demands of triathlon racing. They also often come with features such as visors and easy-to-use straps to help you quickly transition between stages.

What should I look for when choosing a triathlon helmet?

When selecting a triathlon helmet, look for one that is aerodynamic, lightweight, well-ventilated, and fits comfortably on your head. It’s also important to choose a helmet that meets relevant safety standards and has features that will help you during transitions.

Are more expensive helmets better for triathlon racing?

Not necessarily. While expensive helmets may have advanced features and materials, such as carbon fiber or magnetic buckles, they may not necessarily be the best fit or provide the most comfortable ride for your head shape. It’s essential to try on helmets and find the best one for your individual needs and budget.

Can I use a regular road bike helmet for triathlon racing?

Yes, you can use a regular road bike helmet for triathlon racing, but a specialized triathlon helmet will likely provide better aerodynamics and ventilation, which can make a significant difference in your race performance.

Can I attach a visor to my triathlon helmet?

Many triathlon helmets come with detachable visors, but not all models do. If you want a visor on your helmet, make sure to choose a model that has this feature or one that is compatible with aftermarket visors.

How often should I replace my triathlon helmet?

It’s recommended to replace your helmet every three to five years, depending on use and wear. You should also replace your helmet after any significant impact, such as a crash or drop, even if there is no visible damage.

Can I wear glasses with my triathlon helmet?

Yes, you can wear glasses with your triathlon helmet, but it’s essential to choose a helmet that fits well and does not interfere with the placement of your glasses. Some helmets have features such as eyewear docks that make it easier to store and access your glasses during the race.

How do I properly fit my triathlon helmet?

To properly fit your triathlon helmet, first, adjust the chin strap so that it is snug but not too tight. Next, adjust the rear stabilizer so that the helmet sits level on your head. Finally, adjust the helmet’s side straps so that they form a V-shape around your ears without being too tight.

How do I care for my triathlon helmet?

To care for your triathlon helmet, keep it clean and dry by wiping it down with a soft cloth after each use. Avoid using harsh chemicals or solvents that can damage the helmet’s materials. Store the helmet in a cool, dry place, away from direct sunlight, and avoid leaving it in a hot car or other extreme environments.

Are helmets mandatory for triathlon races?

Yes, helmets are mandatory for all triathlon races, including training sessions. You may be disqualified or prevented from participating if you do not have a helmet that meets safety standards.

What safety standards should a triathlon helmet meet?

Your helmet must be an approved ANSI Z90.4, SNELL B90, EN 1078 or equivalent standard and this can be checked by looking inside your helmet. Note that a CE mark is not an approved standard.

Triathlon helmets should meet safety standards set by organizations such as the Consumer Product Safety Commission (CPSC) and the Snell Memorial Foundation. Look for the appropriate certification sticker or label on the helmet to ensure that it meets these standards.

Can I wear a time trial helmet in a non-drafting triathlon race?

Yes, you can wear a time trial helmet in a non-drafting triathlon race, as long as it meets safety standards and does not have a tail or extension longer than 10 cm.

Can I make adjustments to my helmet during a triathlon race?

Yes, you can make adjustments to your helmet during a triathlon race, but you must do so in a designated transition area, and you must not impede the progress of other athletes.

What is MIPS?

MIPS stands for Multi-directional Impact protection. MIPS technology reduces the trauma when the helmet sustains impact from any angle. However, the ultimate goal of using the technology in a helmet is to protect the brain.
