10 Best Triathlon Bike Helmets Tested & Reviewed
Through the decades there has been a push to make helmets have as much protection as possible for all bike enthusiasts. The MIPS (Multi-directional Impact Protection System) has come a long way in innovation by using the slip plane concept. It has a double layer protective barrier and was designed to prevent brain injury and concussions from impact if involved in an accident.
Trimming bike times is essential to triathletes. The aerodynamics that is implemented in the best triathlon bike helmets have come a long way in science and technology–which really allows you to shred that time.
During the mid-1980’s, aerodynamics inside the helmet had improved but were still only available to a select number of athletes. However, by the early 2000’s safety, air flow speed, and an expanded polystyrene core were finally incorporated into the helmet. Today, wearing an aerodynamic helmet is proven to increase speed by up to 10-15 watts–in comparison to a traditional bike helmet.

Criteria Used for Evaluation
Safety is one of the most important factors to consider if you cycle. This is why helmet designs are consistently being upgraded–to ensure your safety and comfort during all of your races. You never know when an accident may occur, so it’s important to cover all your head properly. In the United States, the Consumer Product Safety Commission (CPSC) must approve the product, in Europe, the Conformité Européenne (CE) must approve the product, and in Australia, the AN/ NZS must approve the product.
The fit is the most important aspect because it ensures your comfort and effectivity of your helmet. Make sure your helmet provides a snug and secure fit and that it isn’t too loose. If the fit isn’t right for you then you will not be covered in the case of an accident and won’t receive the safety the helmets are meant to provide you with. The straps on the helmet should also form a V and when you twist your helmet there should be very little movement. The strap will allow you to adjust your fit and ensure your comfort and safety.
Typically, the lighter the helmet, is the more money it will cost you. While this may sound ridiculous to some of you, this is because it is extremely difficult to make a helmet that is both lightweight and able to provide you with the safety you need. Lightweight helmets will allow you to gain speed and help you shed precious seconds off your race time.
Breathability will increase your comfort levels and is crucial for triathletes. However, more airflow requires less padding, which in turn takes away from the safety the helmet provides you with. This is why many helmets employ special channels on the inside as well as holes on the outer part of the helmet. This allows the helmet to be padded and safe–while also preventing you from sweating excessively.
On our list, there are helmets that cost around 100 dollars but there are also products that cost around 300. We don’t want to say that the more expensive the helmet is, the better it is- it’s really untrue. However, the high price of some of the products on our list doesn’t come from nowhere. Extra padding, more ventilation and weight are the factors that decide what will be the price of the product. Triathlon is very demanding and we must be clear- accidents happen.
Even if you’re very careful, the one second may decide. We think that life is priceless and spending even 300 dollars for the helmet is a decision that is reasonable. What’s more, you will be able to use a helmet not only for the triathlon. High-quality helmets can stay with you for years and you can wear even during short ride around the city. There are also many sales and even 20% discount is a lot. Don’t waste your money for cheaply made helmets only because they cost less. Your safety is the priority and stick to this rule.
Other Factors to Consider
Size and style because they can affect many other factors. A helmet that is too small can be too tight and will decrease your blood flow. On the other hand, if the helmet is too large it won’t provide you with the safety and protection you need when you are out on your bike. If your helmet is too big there are caps you can use to make it fit better.
As far as style, you can find options that come in lots of different colors and pattern options. Some are sleeker than others while others are bulkier–so you have a variety of options to choose from.
Our list has helmets between $100-$300. Price will depend on the features you are looking. So, before making your purchase make sure you are getting something that fits your needs and preferences. Some helmets may also come with hair ports, Reflective features, or even additional lighting options. Make sure you aren’t paying for features you don’t need!
Selecting the perfect helmet can be a difficult purchase to make. You have to consider safety and whether a MIPS helmet would be a great fit. Then there is, of course, the aerodynamics to consider in order to shave off as much time as possible on both trials and competitively.
Comfort is just as important. It has to fit your head right without moving too much and the size is imperative because you don’t want a tight fitting helmet. The cooling mechanisms are a must for even the most serious cyclist and you have to be able to put water into the helmet for a fast and rapid cool down. All of the helmets reviewed have a combination of what athletes and triathletes alike are looking for, now it is just a matter of choosing one and getting out there for fun, competition and a healthier lifestyle. Comfortable helmets will prevent neck strain during your runs, will stay put, and prevent you from overheating. The chin strap should provide an adjustable an secure fit but should not be uncomfortable nor should it pinch you. The earflaps on aerodynamics helmets should to stay put and be comfortable enough to wear during long races.
Frequently Asked Questions
MIPS Technology stands for Multi-directional Impact Protection System Technology. This method of making helmets allows for more protection because the additional layer it gives your helmet reduces the rotational forces that can happen if you get into an accident. This technology was invented in Sweden and has been tested for almost 2 decades–so you can rest assured that it will keep you safe.
Recreational helmets are the simplest type of helmet. They are used for recreation as the title implies, or by people who commute to work. They are economical and perfect for commuter, road and mountain bikers. They often include visors to shield your eyes from the sun.
Road bike helmets have more advanced aerodynamic features and are much lighter than recreational helmets These helmets allow for a wide view, so you can clearly see if there’s a car coming your way.
Mountain bike helmets are perfect for people who ride downhill and need good ventilation. As the terrain is very demanding and it’s really easy to get hurt, the helmet has a hard shell and the straps are very firm.
That’s a good question. The most important thing we can tell you here is to not use harsh chemicals. Instead, use mild soap and water and make sure to keep your helmet in a cool and dry place.
If you get into any type of accident it’s important to replace your helmet–even if it looks okay. However, if you have not been involved in a crash, most manufacturers recommend you replace your helmet every 4-5 years. While they are durable, the older they get the less safe they may be.
