10 Best Triathlon Bike Helmets Tested & Reviewed

1

There are three important aspects that go into selecting The Best Triathlon Bike Helmets–Safety, Aerodynamics, and Comfort (the most important being safety).

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 are 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 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.

Here Is How We Evaluated The Best Helmets

After our reviews, it’s time to show you how we picked up the top 10. It wasn’t an easy task but we’ve made up a list with most important factors.

Safety

When the cycling is developing more and more, there’s growing need for safety. Cycling may be a nice hobby but it can be also an extreme sport. That’s why people started to upgrade the design of the helmet in order to enlarge safety. As there are many accidents connected with cyclists, governments in many countries decided to put forward the standards and requirements that manufacturers should meet. These standards have different names in different regions of the world.

In United states. Consumer Product Safety Commission ( CPSC) must approve the product, In Europe, it’s CE( Conformité  Européenne ) and in Australia, it’s AN/ NZS.

When it comes to safety, hard and durable material is the key for our protection. Polystyrene is the most common used material. It’s main aim is to absorb the shock and when there’s an accident with big impact, it may even crack. It’s normal and you shouldn’t be shocked- just don’t use it more.

Fit

There’s no way that the helmet will provide protection if it doesn’t fit.  How to check if the helmet fits you? At first, you need a helmet that is tight enough. We know that many of you don’t like have anything on the head because it’s heavy and there may appear sweating problems. However, wearing the helmet tight enough is essential. This is because, when you wear your helmet too loose, it may easily come off your head. This may especially happen during the bike accident and without the helmet, the risk of serious injury or even death is very high.

Of course, it can’t be too tight as your head needs blow flood. Even if it’s worn tight, you should be able to wear it for many hours. The straps should form the V and they should meet just under the ear. You need to see everything so if helmet slips to much over your eyes, try to adjust a little more tightness. Even if you try to twist your helmet, there should be only little movement. The helmet line should be a little above your eyebrows. There are many different designs of the helmets and many different shapes. The best option is to try on many various models and choose the best one.

Weight

Many people is really surprised when they get to know that the lighter helmet it is, the more expensive it is. It may sound really ridiculous as first but it’s true. You may wonder why it’s so hard to make a lightweight helmet. You may think that’s only a lot of special materials and holes in it. However, even though, there’s really good material, it has a tendency to split. This is why manufacturers use hard plastic shell to provide more protection for our heads.

Also, additional straps are added in order to be able to adjust the tightness.  A weight may be also a big obstacle for those who don’t like big, chunky helmets because it can really have a big impact on the comfort. Don’t expect your helmet to be very lightweight, as without padding and additional safety features, your ride won’t be safe.

Ventilation

Keeping cool is crucial for triathletes as it’s much more comfortable for them to ride without sweat all over the head. It may be a little problem here – if you want more airflow, you get less padding. Less padding means that your ride is less safety. You need to balance those two factors. The ventilation system isn’t very complicated. There are usually holes in the helmet to provide air flow. However, if you really want to stay cool, look also for products with special design. We mean that there should be also special channels inside the helmet and thanks to them, the air can reach the hottest parts of the head. A good ventilation system will let you enjoy riding for many hours even if you have a problem with over-sweating.

 

More Stuff Worth Thinking About

Size and style

The size is a big problem while choosing the helmets. It’s really hard to find the best size because many people are usually between sizes. You can wear smaller size but you must be aware that it will be very tight. If you feel like your blow flood is decreased, better buy a larger size. When your helmet is too big, it may not give you enough protection and it may come off your head and during the accident, it’s really dangerous. You can wear for example a cap or something and then you put the helmet on and it should be okay.

You can easily measure your head- just put the tape measure around your head. It should be the largest part of your head so it’s little above the eyebrows. Next thing is the matter of look or design. How do you want your helmet to look like. We are sure that you know the look is less important than safety and comfort but who would like wear something ugly? No one. Try to find a helmet that above all the basic factors like providing safety, comfort, size has also nice appearance. While reading reviews, we found out that people complain very much about not big enough range of colors. It’s really useful to find helmet with flashy or white colors in order to be visible. Helmet with reflective lines or logo is also extra both for us and for drivers.

Price

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.

Does it have a guarantee?

You may not even know how important the guarantee can be in case of helmets. The main task of the helmet is to protect your head from damages. What happens if you decide to buy one for 200 dollars and few days after, because of an accident, your helmet is useless. You really need to look for helmets with a decent guarantee. Of course, not every manufacturer will give you a new helmet because you had destroyed the previous one, but there are brands that offer this kind of service. What’s more, a guarantee is a good thing when your helmet was delivered damaged or with defects.

And what about the way of shopping? In this case, it will be better for you to find the product in the store. It’s rather hard to purchase the helmet without trying it on. The fit is a key to safe and comfortable ride so don’t hesitate and visit the nearest store. At least, you can find an appropriate size and then check if on the Internet it is cheaper.

Additional features

When we were talking about the look, we mentioned that reflective symbols on the helmet may be very useful. They’re not the only features that we can have – there are much more of it. Have you ever had this feeling of being blinded by the Sun. We know this feeling very well and that’s why we want you to know that there’s solution for it- visor. It is attached to the helmet and it makes much easier for us to see.

The visor isn’t usually very heavy so it won’t be much to the weight of the product. There are some models that have special protection for the chin. Manufacturers are aware that people are very demanding and they won’t to look good and feel comfortable with the product- that’s why special hair ports are growing in popularity. If you want to wear a helmet and a ponytail at the same time, it won’t be a problem. Less common feature is lighting in the helmet which can make you even more visible for the others.

 

FAQ

Q.What is MIPS Technology?

A.MIPS Technology stands for Multi-directional Impact Protection System Technology. This is the method of constructing helmets that gives more protection than the previous methods.  How it is done?  If your helmet has MIPS Technology, there’s an additional layer in your helmet. It can reduce rotational forces-a one of two forces that can appear during  bike accidents. The other force is called linear. Whenever you have an accident, there’s usually combination of these two forces. It means that MIPS can give you more protection in particular cases. MIPS is a new technology, invented in Sweden and has been tested for almost 20 years. It doesn’t matter if you are a professional cyclist, or you just use a bike for a relaxing ride, it’s really worth to have a helmet with MIPS.

Q.I’ve heard about different types of bike helmets. Can you describe them?

A. Yes, here are the most popular types of bike helmets:

Recreational helmets are the simplest type of helmet. They are used for recreation as the title implies, or by people who commute to work.

Recreational helmets are an economical choice for recreational, commuter, road and mountain bikers; they’re also popular with skateboarders and inline skaters. They often include visors to shield your eyes from the sun.

Road biking helmets have more advanced aerodynamics and manufacturers try to make them the lightest they can. Cycling on the road may be dangerous and that’s why this type of helmet provides a wide view and you will be able to pick the car out.

Mountain bike helmets are perfect for people who ride downhill and they 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.

Q.How should I take care of my helmet?

A. That’s a good question. Here we go with a piece of advice. The first important thing is cleaning. You shouldn’t clean your helmet with very harsh chemicals. Mild soap and water will be the best solution. You need to keep your helmet in dry and cool place. Too much heat is never a good idea. The little bubbles may appear on your helmet and you won’t be able to use it again so attic or car trunk aren’t the best places for a helmet. The thing that may seem strange is that you shouldn’t lend your helmet. You never know what happened to your helmet when it wasn’t on your head. This is a big thing because if there was a crash, your helmet needs to be replaced. You can’t use your helmet even if it wasn’t destroyed because you don’t know if it still works well.

Q.How will I know that I need a new helmet?

A.You are always obliged to replace your helmet after crash. Even if it looks okay, it may not work so it won’t provide safety. However, if you didn’t have any crash and you don’t know how long can you use it, most manufacturers recommend to replace the helmet after 4 or 5 years of usage. Helmets are rather durable but there will come the time when it will be too old and less safe for you.

Comfort is also key for long rides and neck easement. It has to stay put and not overheat. The chin strap needs to stay secure and not pinch or be uncomfortable.  The earflaps on the aerodynamics helmets need to stay put and be comfortable for the long course races and you have to make sure that you have an overall overheating mechanism built with the helmet whether that be a water spout at the base of the helmet or the overall material to keep your head from the infamous overheat

With that said, we have selected six of the best helmets on the market to date that will cover all of the those questions, plus give you the most bang for your buck.

 

Summary

Selecting the perfect helmet can be 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.
