How Do Mountain Bike Helmets Work?

Mountain bike helmets focus on increased protection and adaptability. Unlike road bike helmets, which serve as protection that is both ventilated and aerodynamic, mountain bike helmets need much more structure.  

Because mountain bike trails lead through narrow spaces with lots of potential debris, crashing can become much more dangerous. Barring the fact that you can’t get hit by a car when you’re on a trail, mountain biking involves traveling downhill at high speed and can require much more control than if you’re riding on a straight and well-paved path.

Therefore, mountain bike helmets need to provide certain protection that a road biker helmet doesn’t. Specifically, they need more protection over the base of the skull and the top of the spine. Mountain bike helmets also feature heavier materials to prevent scrapes and abrasions and often cover more of the face to protect from branches.

Usually, mountain biking is undertaken at lesser speeds than road biking because there’s a lot more vertical change. Slower speeds mean mountain biking helmets don’t need to be as aerodynamic. Because of this, mountain bike helmets can use visors. 

Visors are an essential element of mountain bike helmets because they keep the sun off a biker’s face. Riding in an upright position, as on a mountain bike, means light casts a greater influence on how a biker can perceive their surroundings. 

Road bikers don’t need visors because their position allows them to focus on the path directly in front of their tires. In contrast, mountain bike riders have more risk of sunlight distorting their vision, so their helmets require visors to prevent blindness.

How to Choose the Best Full-Face Mountain Bike Helmet

Mountain bike helmets have several features to consider before you take one home. 

Fit

Every helmet you own should fit your head. However, not every skull has the same shape. Trying on a helmet is the only way to see if it can properly fit. Some manufacturers might have a wider or narrower build depending on their preferences. Some might have a rounder interior or a boxy one. 

If your head is a more unique shape than most, you might have to do some searching before you can find a manufacturer who provides the perfect helmet for you.

Thankfully, all helmets have some ability to adjust to unique shapes. Full-face mountain bike helmets are less forgiving than open-faced mountain bike helmets, as they generally have two different kinds of padding (thinner or thicker) for adjustability. Open-faced helmets, by contrast, can be more flexible in terms of straps and interior comfort.

Ventilation

Protection doesn’t necessarily involve coverage from potential crashes. It also prevents sticks and twigs, and other debris from becoming stuck in your helmet as you fly past. But more coverage results in less ventilation. A more ventilated helmet will provide you with relief, but it’s not worth it if you always bike in heavily wooded areas.

Structure

A helmet with a poor structure is a terrible choice all around. A structurally sound helmet designed to withstand spills is essential. Today the design of full-face helmets incorporates post-crash recovery to provide better protection than ever before.

Eyewear

Goggles are necessary for complete eye protection, especially with full-face helmets. If you want to keep your goggles on your head, your helmet should be able to hold them securely. Grooves and clips for goggle straps will prevent unwanted movement, so your goggles always stay on your face.

Injury

No matter how cautious you are, spills and injuries can still occur. Therefore, many mountain bike helmets have evolved to accommodate potential head and neck injuries with easily removable chin guards and inflation systems that help stabilize the neck. 

Type Of Helmet

You can choose between a couple of different types of helmets:

Full or Half Face

Riders who love to tear down the steepest slopes for a wild ride favor full-face helmets. These helmets provide more protection than the half-face ones by far. However, full-face helmets are hard to breathe in, especially if you’re climbing hills. So, bikers who love to use their legs instead of a lift to gain elevation prefer half-face helmets.

Convertible

A convertible helmet switches between full and half face by removing the chin guard. If you like switching up your terrain, you can consider buying a convertible. It protects the same as a full-face helmet and is breathable as a half-face if you’re working hard. 

Conclusion 

For the best overall mountain bike helmet, the Fox Racing Rampage Carbon encompasses all aspects needed on the trail. Not only is it one of the safest helmets available, but it also has substantial ventilation and durability, not to mention you can choose the non-carbon version for less expense.
