Various Types Of Mountain Bike Helmets


Headgears may come in three different kinds: road, recreational, and mountain. All of these kinds will ensure you of the protection you need against head impact. Plus, they are very comfortable and lightweight. Here are the differences of each type:

Recreational Helmet

These are the most economical option for the commuter, recreational, mountain, and road bikes. They are also well-known with inline skaters ad skateboarders. They come with visors to protect the user’s eyes from the sunlight.

Road Bike Helmet

These are for road enthusiast that offer ventilation, little weight, and aerodynamic feature. These headgears do not usually have visors. That’s why they are lightweight and offer an obstructed view, especially when you are in a crouching position while riding.

Mountain Bike Helmet

These are for Cyclo-cross riders. They provide enough ventilation at low speed. They have a well-enhanced rear head cover and have a secure fit. Thus, they are suitable for rough terrains.

Some of these helmets offer a full-face coverage that park riders and downhill mountain bikers want.

How To Choose A Mountain Bike Helmet


Here are some of the most significant factors and features you need to search for in a helmet:

Construction of the Helmet

A lot of head gears utilize an in-mold construction. It is a well-known method that links an inner liner with the outer shell without glue. It results in a light, but durable design.The weight won’t cause a massive impact for occasional racers and cyclists. However, pro riders want their weight-saving feature.

Shell of the Helmet

A majority of cycling head gears have covers that provide plastic shells to hold them together, especially in a bike crash. Also, they offer puncture-resistant features. It will enable the gear to slide on high impact to protect your neck and head.

Liner of the Head Gear

Most of the lining of helmets have expandable polystyrene foam. On a collision, the lining drives away the pressure to protect your neck and head. But, you need to ensure the liner fits well in your head.

MIPS Technology

Other helmets will provide a technology called the Impact Protection System or MIPS. It is a process of making the helmets that provide enough protection from forces during a bicycle collision.

Helmets with MIPS innovation will have a low friction lining that enables the helmet to absorb the impact.

The foam liner will slightly allow you to rotate your head during a bike crash. But, it will only move for a few millimeters. It will decrease the rotational impact that will transfer to your brain during impacts.

Other Vital Features Of Biker Helmets


Here are the additional features you need to look for in a head gear:


Other riders want to have a shielded screen connected to their helmets to provide sun protection. A display is typical on a mountain bike helmet. However, it adds more weight and a little wind resistance.


Helmet ventilation will improve the wind-flow. So, it will keep you more comfortable and cooler as you ride your bike. The more ventilation the gear provides, the lighter it will be.

Full-Face Protection

Other bike helmets have coverage to the chin to give your face enough protection for park riding and downhill mountain biking. Some racers also enjoy this extra feature for difficult terrains.

Helmet Straps

The straps will provide comfort. Plus, they are easy to clasp and unfasten.

Hair Port

Some headgears will come with straps that can accommodate your ponytails.

Finding The Ideal Sized Bike Helmet


When selecting a mountain bike helmet, a well-fitting gear is crucial. Most helmets will come in small, medium, large, and XL sizes. To look for the right size helmet, you have to use a tape measure around the biggest part of your head.

Most probably, this will be around 1 inch on top of your eyebrows. You can also choose a ribbon or a string to wrap around your head. Then, you have to determine the length of your string.

Adjusting Your Bike Helmet


A well-fitting helmet should be snug enough, but it won’t be too tight. It should have a level close to your head and with a front edge about 1 inch or less atop your eyebrows.

By doing so, you protect your forehead from the impact. You have to push the gear from each side and from back to front. If you notice that it shifts, you have to adjust the helmet.

Next, you have to regulate the fit by expanding the regulating wheel before you put the helmet on your head. Helmets usually come with a sizing wheel.

Once you wear the helmet on your head, try to make contact with your head. Then, you have to tighten the ring of the regulator until it fits well.

Moreover, you need to fasten and tighten the chin strap. The straps should come up with a V shape as you put them below your ears. Also, you need to regulate the straps around your ears until they fit comfortably.

Lastly, as you buckle the chin strap, you have to open your mouth wide enough. The gear should press above your head. If not, you have to tighten it once again. But, remember not to tighten the strap too much until it becomes uncomfortable.
