Of course the question becomes: how would to begin your research on the many different kinds of mountain bike helmets? We’ve rounded up a few questions so you know what to consider when choosing the helmet for you.

How do I choose the right helmet for me?

Different riding habits require different qualities of helmets. Falling under two main categories, mountain bike helmets ideal for riding on the road or flatter off road trails tend to be half shell, and full face protection might not be that necessary as it is with motorcycle helmets.

They are also lighter and are better ventilated since you might prefer comfort over high level of impact protection. Full face, on the other hand, make for better protection on higher-risk roads, such as downhill. Another thing is knowing when’s the time to replace your helmet.

    How does a helmet work and what kind of protection does it provide?

    A helmet protects you from potentially fatal brain, head, and neck injuries. It manages that by its styrofoam padding, which crushes to control crash force, reducing peak impact to the brain.

    What is MIPS and why is it important?

    MIPS stands for Multi-Directional Impact Protection System. It’s a layer of light plastic that sits between you and your helmet, providing relative movement of your head and helmet in the event of forceful impact, and reduces the chances of rotational brain injury.

    Giro Chronicle MIPS MTB Bike Review

    Another key safety feature is that the interior is fully wrapped with an EPS liner that adds an extra layer of protection which absorbs forces under impact, protecting your head and neck in the case of a crash.

    Giro Scamp Youth Bike Helmet Review

    Mountain Bike Helmets: Frequently Asked Questions

    How Do I Make Sure the Helmet Is a Good Fit?

    For the best protection, a helmet should feel like it sits low on your head. The side pads and straps should be adjusted so that your helmet touches all the way around the brim with the sides meeting just below the ear, and the chin strap wrapping snugly and not too tightly.

    A helmet that is a good fit for you will have you forget you are wearing it most of the time, so if you’re able to move the helmet more than an inch backwards or upwards using your hand (a good test to check for the right adjustments), you should probably tighten the straps.

    Not everyone gets the chance to do that, but trying on the helmet before buying it is the best way to go.

    When Should I Replace My Helmet?

    Generally, a helmet is best replaced every 5 years or when it no longer fits you. You should also replace your helmet right after any accident where you hit your head.

    Any damage done to the foam part of the helmet will not be seen, so even if you think your helmet’s still okay to use, you must know that the styrofoam is one-time use only and loses its protective qualities upon impact.

    Is It Okay to Buy a Secondhand Helmet?

    Usually, it isn’t the best idea to buy a used helmet. As with the previous answer, damage done to the helmet’s foam after accidents isn’t visible, so you won’t be able to tell whether or not the used helmet is still viable for protection.

    Investing in a new helmet better ensures your protection and safety, and it doesn’t have to be that expensive anymore with many efficient and affordable options on the market, some of which we’ve mentioned above.

    What Am I Compromising When Buying a Cheap Helmet?

    As with the difference between MIPS and the less expensive non-MIPS helmets, the former further ensures your protection, so investing a little extra might come in handy.

    Sometimes both cheap and expensive helmets surprisingly perform very similarly and share many features.

    It’s always important to know what you fully need out of a helmet and to have it be an ideal fit for you, so if a helmet will not offer that much protection or is not a right, comfortable fit for you, it might be worth it to go with the more expensive helmet.
