Mountain bike helmets are by far the most important gear that is crucial for your safety. Mountain bike helmets come in a wide array of models, shapes, and designs to meet the bikers’ needs and requirements.

For instance, some bikers probably want to focus on riskier forms of riding like downhill. Such risky activity will need extra protection. Therefore, they will need to wear the full face mountain bike helmet for solid protection. Meanwhile, the cross country mountain bikers would need to wear open face helmets for good ventilation.

1. Troy Lee Designs A2

The helmet uses an innovative design with two types of foam: EPS, which is found in most bike helmets for absorbing impacts at high speed, and tough EPP for low-speed crashes. With MIPS, a low-friction layer slides 10 to 15mm in all directions, reducing rotational motion to the brain during impact. Comfort is near the top of the pack with a minimalist but smart design with thick padding around the forehead. The helmet features multipurpose cam-lock adjustable stabilizer and full spectrum adjustable visor.

Helmet Categories

Cross-Country (XC)

The Cross country or XC helmet tends to be lighter and more open. The type of helmet is more vented than the other types of mountain bike helmets. Sometimes, people mistakenly pinpoint it as an enduro helmet while the huge difference is in its ventilation system. XC helmets are more open to give the perfect ventilation. It is also more lightweight.

All-Mountain

All-mountain bike helmet has more coverage on its part. It comes with the peaks to keep the sun or rain out of your eyes. Well, the design does make sense because it is specially created for multiple mountain bike disciplines such as cross country, trail riding, Enduro or all-mountain, downhill, freeride, and dirt jumping. If you are not yet specifying your discipline, or perhaps wanting to explore all of the disciplines before determining one, you could use this All-mountain bike helmet. All-mountain helmet is the most versatile amongst all types. You can use it for multiple purposes.

Downhill

For extreme chasers, you cannot go wrong with the Downhill mountain bike helmet. In downhill discipline, the key to solid performance is speed and extreme. Therefore, you will need to cope with the speed and hard imp[acts. In this case, you will need a full face helmet to completely protect your head. Downhill mountain bike helmets usually come with extra padding and wrap to protect you from heavy impacts. The good helmet for extreme activities are the models which come with MIP protection. We’d go down with it in the next point.

Helmet Weight

The weight of the helmet is also an important aspect to consider. You must choose the helmet which is not too light, or not too heavy. The typical mountain bike helmet weights can be around 28 to 32 pounds at max. Lighter helmet is usually better if you are doing all-mountain or cross-country missions because you will need more endurance with adequate protection. But for the extreme ones, you could use a heavier helmet. There’s a good reason for this. Most of the downhill mountain bike helmet comes with extra padding. That explains why these helmets tend to be heavier than their brothers.

Ventilation

Helmet ventilation is the key to your game. The ventilation ports in the helmet will help the bikers to draw the air and breathe out to the right exit points. But there’s an important part besides the in and out points: the convection. The convection has the cooling effect which is the supportive key to the endurance of the biker. If you are looking for endurance, consider picking the helmet with the larger front vents. But in some cases, it might hinder your speed because of the g-force in the denser foamed helmet. In a nutshell, larger ventilators are not always better.

Helmet Fit

The fit of the helmet is altogether with safety and comfort. When it comes to the helmet fit, it will be down to the personal choice, rather than authorized tests. Some helmets fit might be better for your friends, but not yours. So, how to find out the best helmet fit for you? First things first, make sure that the helmet is in contact with your entire head, just above the brow. Make sure that you have clear vision when wearing the helmet. The ring system in the helmet should be tight enough, but not make you uncomfortable.

Consider to choose the models with multiple height adjustments to make a more appropriate tuned fit. Also, consider checking the straps of the helmet.

While it is a great idea to check the helmets physically when visiting a brick-and-mortar store, you could also get the best helmet from an online store. But when you purchase online, make sure to double check the measurements. The last thing you want is that you receive too small or too large a helmet at your home.

Padding and Comfort

The padding quality is the key to the safety and comfort of the mountain bike helmet. In common cases, the more padding will reduce the acceleration and impacts to the head. When a helmet is able to reduce the acceleration to the head, it will reduce the risks of concussion when the greater impacts happen. As much as important is safety, the padding can also give comfort to your head. Wearing a helmet does not necessarily make you inconvenient, right?

Helmet Safety: MIPS, SPIN, Turbines

There are some helmet safety systems that you need to comprehend: MIPS, SPIN, and Turbines. What do they mean?

MIPS

MIPS is a thin layer of material which is placed between your head and your helmet. This layer gives slight flexibility in your helmet to allow it rotating when your head receives an impact while wearing your helmet. The slip plane system in the MIPS will protect your head from impact.

SPIN

When it comes to the mountain bike activity, you will be challenged with various impacts and forces. One of the most significant forces to consider is the rotational force on your brain. Therefore, you’d like to pick a helmet with SPIN. The SPIN system is easy to understand. It uses the pads on the interior to reduce the rotational force medley.

Turbine Technology

Turbine Technology uses the system which inserts the circular flexible pads into the liner of the helm. The turbines are distributed through the liner. The main objective of this safety system is to absorb the impact maximally and prevent the conclusion. It also helps to reduce the rotational forces around the brain.

Mountain Bike Helmets Price Guide

If you are serious with your mountain bike interests, you need to spare anything between $100 to $350. The good news is that most of the types of helmets come within this price range.
