When it comes to cycling there is one key accessory that everyone should properly invest it. A helmet, whether you choose one that is simple or integrated with aerodynamic technology, a helmet is the one investment that you must rely on if something happens. I’m here to help you find the best road bike helmet that fits your needs and your wallet.

What Makes a Helmet safe?

It is a well known fact that by wearing a helmet it will protect you and can even save your life. Let’s take a look at some of the factors that make a helmet strong enough to offer you this protection.

Polycarbonate shell

Polycarbonate plastics are frequently used to make helmets. This is because they are incredibly durable and lightweight with loads of impact resistance. Also, this material is low cost to manufacture, making it the perfect choice for safety.

EPS Liner

The EPS (expanded polystyrene) liner is made for absorbing the shock of an impact. This liner is great protection in the event of a hard hit, as your helmet won’t bounce on impact with the ground.

Instead, the helmet will absorb the shock of the hit, keeping your head from bouncing around and protecting you from pain or internal damage. While it is excellent for protection, this liner is not good at absorbing multiple large hits and shocks.

In-mold technology

This helmet construction technology is made to be very lightweight, while still keeping a strong protection. This effect is created when the foam liner of the helmet is blown in while the outside shell is still in the manufacturing mold.

This gives the helmet a lightweight design, allows it to have a more interesting shapes and gives the helmet a better vented integration.

Back of helmet adjustments

Recently helmets have started to add an extra level of comfort and security, known as Retention. This easy to reach knob is located on the bottom back of the helmet. With a few turns you will begin to feel the helmet start to contract in, cradling your head and giving you a no-slip fit. Once adjusted, you can turn your head upside down and the helmet should not fall off without the straps on.

This new feature gives riders a better grip and provides better protection from impact since the helmet will remain in place. This feature is mainly featured on higher end models, but can appear in some affordable options as well.

CPSC certified

The Consumer Product Safety Commission has a basic set of standards for all bike helmets to determine whether they are labeled as safe or not. If you are wondering, you can easily look inside a bike helmet and you should see the sticker showcasing the certification.

This certification ensures that the helmet has passed a number of tests that look at the following:

  • Shock Absorbing Properties
  • Helmet Construction
  • Retention system
  • Field of Vision
  • Chin Strap
  • Fastening Devices

Night riding

What you should look for is a helmet color that has reflective paint integrated into the design. This is a must-have if you are riding at night. Some helmets offer neon colors, while others keep a standard simple color and add reflective neon accents.

Some manufacturers install rear caution lights in the back of the helmet. These lights blink or flash with a bright light to alert drivers. When you are riding at night, you need to have some level of reflection or light so that drivers and other individuals can clearly see you.

How to prepare for buying a helmet?

 A few preparations will give you the upper hand when you begin to shop for a helmet. Whether you go in a store or shop online, a few things to consider beforehand will help you when you start looking.


When you start shopping, one of the first things you need to determine is how much you want to spend. Helmets can range from $40 to over $300. One thing you need to know is that a lower priced helmet is not less safe than a higher priced helmet.

All countries have a minimum safety standard that helmet makers have to meet. In the end, when you are paying for a pricier model, you are paying for a different fit, material or just for the name brand.

Head sizing

It is a good idea to measure your head with a soft measuring tape before you shop. This will give you a better idea of what size fit you will need. When measuring your head, wrap the tape around the back of your head, just above your ears and back around to your forehead.

bike helmet sizing

Most helmets will come in a few sizes ranging from small to large. Keep in mind, some of the higher end helmets will have an adjustment gauge in the back to give you a closer fit.


The aerodynamics of a helmet come down to the way a helmet is shaped and how well it resists wind. Helmets that are more vented will take in more air which lowers the level of aerodynamics. A closed helmet will allow wind to wash over it without much collective resistance.

Aerodynamics of bike helmet

If speed is a large factor in your riding, you should opt for a less vented style. Some styles on the market offer a convertible open vented style that can close when you need better speed.


This refers to the cut away on some helmets that leave holes in the top. These vents allow cool air to filter into the helmet and push out stale air that can cause your head to overheat and sweat.

helmet ventilation

Ventilation is a great option to look for, especially if you will be riding on warm days. If you are prone to riding your bike in cooler zones, then you may want to consider a more closed option to keep your head warm.

Rider type

Finally you need to find out what kind of rider you are. Will you be plummeting down hills at top speeds, racing others or simple peddle down streets at a leisurely pace? Realizing what type of rider you are will give you better insight into what key features you really need and what you don’t.

bike rider type

If you are more leisurely, then you don’t really need the most high-end helmet; a simple one will do. On the other hand, if you are frequently biking in races or take more risky routes, then you should look at more durable and higher – end helmets.

At the end of the day, it really comes down to what you like and what fits well. While all helmets are not made alike, they are all made to be safe. So whatever you decide on, the main feature of safety is covered.

On a final note, if you have a significant crash, you should check with the manufacturer to see if they offer any discounts on a new helmet. It is not advised to continue with your helmet if you take a very hard hit, even if there is no damage showing,. Internally, it could be fractured, offering you less protection in the event of a second hard crash.
