Buyer’s Guide

Getting the right road bike helmet depends on a number of factors, including how long do you plan to wear it, how sensitive your head is, etc.

Types of Bike Helmets

There are several types of bike helmets and here are the three most common that you should know how to distinguish.

Commuting Bike Helmets

Commuters’ helmets are made for people who bike to work or school daily without regard to top-level performance. They are made to be comfortable all-year-round, providing cooling in hot weather and warmth when it’s cold out.

The most significant difference between commuters and racing road bike helmets is the weight. Commuting helmets are slightly heavier but that’s only because advanced materials are not necessary. As a result, they’re far more economical and a decent helmet of this sort starts at $60 or maybe even less.

Performance Bike Helmets

Performance helmets are lightweight but they can also be costly. They’re made to help competitive cyclists enhance their performance in races, especially on mountainous terrains. In challenging conditions, even the slightest difference in weight can make a difference.

That’s why helmet manufacturers are competing in coming up with the most compact and lightweight helmet (without affecting safety, of course). Performance helmets are nice to have and they definitely feel great on your head, but you don’t have to reach for you if you don’t want to.

Aero Bike Helmets

This is among the latest designs in the world of high-end bike helmets. The idea is to help cyclists perform better by way of aerodynamic. The manufacturers are still trying to figure out the shape that would work best, so there are multiple highly distinctive shapes on the market.

The only downside to aero helmets is that they’re often not ventilated and devoid of any thermoregulation system, which is the reason why some people avoid them. They can be an excellent choice for when it’s nice out, but not so much when the weather is overly hot.

Fit and Comfort

The most important thing with respect to choosing a road bike helmet is to make sure that it fits properly. It means that it should be comfortable and not too tight or too loose. Although you can just measure your head at home and find your size online, it’s recommended to try out several models before you make a final decision.

For extra comfort, look for models fitted with soft padding inside. Make sure that the padding is removable and washable, or else you could run into problems in the summer days when you sweat profusely.


The ventilation is another essential factor, especially for those who go on long rides. You should look for a helmet that has multiple holes in the shell for air circulation. However, keep in mind that less-ventilated helmets can be warmer and more suitable in cooler climates.

Alternatively, you may want to go with a ventilated helmet that’s equipped with warm internal padding. It could very well be a winning combination for all seasons.


The driving force of the industry these days is to produce increasingly lighter helmets that can also deliver safety and comfort in spades. People prefer lighter helmets for one reason: the lower pressure on your head and neck allows for a wider range of motion.

Professional bikers would tell you that even a 50g difference in weight has an outsized contribution to the performance. The only downside is that the lightest helmets also tend to cost a bundle.


Aerodynamics is a big deal with competitive racers, which applies to everything that they wear including clothes and helmet. By reducing the drag, aerodynamic helmets can only enhance your speed, allowing you to ride faster and smoother. Investing in a quality aerodynamic helmet could improve your results significantly.

However, there are two downsides. First, this is a relatively new feature that’s usually reserved for competitive cyclists. You can count on these helmets to be pricey on account of the R&D that goes into them. Second, which may not be a big deal to many people, aerodynamic helmets often come with funky shaped lids.

Final Thoughts

You can’t go wrong with any of these five helmets. What’s more, you now know how to determine whether a helmet offers the appropriate protection or not, so you’re able to make your own decision.

Just for the sake of naming one, the overall best road bike helmet currently available on the market is the Giro Aether Spherical Adult Road Bike Helmet. This model not only offers supreme protection, but it’s also designed with excellent ventilation and temperature regulation so that you can wear it all-year-round.
