Similarly, many types of bicycle helmets are also available to cover the needs of different cyclists. Specific helmet designs are available for mountain biking, track racing, time trial, bike commuting and road biking.

You can also find mountain bike helmets tailored to downhill riding, dirt jumping, endure racing and cross-country riding. Literally, dozens of manufacturers produce bike helmets.

Some of them are very popular, but the others are not so much. Many different brands and technologies are available. Therefore, choosing the right helmet is a daunting task.

There is a very little structural difference between the desired features of a mountain or road bike helmet, though the styles will vary. Mountain bike helmets may have integrated visors, but this feature will be absent in road cycling helmets because they usually impede vision while using with a drop handlebar.

While dirt jumpers prefer increased protection, cross-country riders prefer ventilation and light weight.

The priority of a road racer can be aerodynamic qualities, but a weekend or a commuter warrior prefers ventilation and protection. Regardless of your riding style, here are a few things you should look for while purchasing a bike helmet.

A. Things To Consider 1 : Protection

Protection is the most important factor of a helmet. There are lots of government-instituted standards, and all of them should be followed while manufacturing a helmet.

These standards can vary between continents or countries. In the United States, helmets must have CPSC approval, In Europe, CE sticker must be checked, and in Australia, it must be AS/NZS. Shock-absorbing expanded polystyrene is used for manufacturing most helmets.

Shock-absorbing expanded polystyrene is used for manufacturing helmets. So, when you meet with an accident, the helmet will be crashed itself.

Therefore, you can see a cracked helmet after a big impact. It means the material is doing its job. You should not use the helmet again once it is broken.

Today, almost all helmets are in-molded. So, the protective inner material and the outer shell are molded together for providing extra strength.

Systems such as Mips can be found in certain mountain bike helmets, which offer additional protection from rotational impacts, which are more frequent when out on a ride. Today, some mountain bike helmets even offer increased protection with a greater coverage and deeper fit at the back.

B. Things To Consider 2 : Ventilation

When you work hard, your head is the most important place, which helps your body regulate heat. Therefore, ventilation is extremely important for keeping you cool when temperature shoots up.

Usually, ventilation takes the form of multiple exterior vents or holes, air can flow directly to your head through these holes.

However, proper ventilation not depends on the number of holes. A well designed internal venting is also greatly important. In this design,
the air channels are carved into the inner shell, which helps to direct air effectively to the hottest parts of your head.

Then, this air is channeled to large exit ports. In such a way, your helmet can easily prevent your head from overheating.

Larger, more open vent holes are the peculiar features of some mountain bike helmets. Compared to road cycling, mountain biking requires lower average speed. The vent holes are larger and more open due to this reason. But these types of helmets are not suitable for road cycling because they can create greater wind noise.

C. Things To Consider 3 : Fit and Adjustments

Your helmet should not be too tight. It should be a comfortable and snug fit. If you measure your head, you can make a perfect move.
To do this, you should measure the circumference of your head, which helps you to determine what size should try on first.

You should try on plenty of different models and makes. The internal shape of all helmets is not same. Some manufacturers design their helmets in different models such as more oval, rounder, etc. Therefore, you should find one, which suits your head perfectly.

The helmet should fit properly and stay in place during the event of a crash. In order to ensure these features, every helmet comes with a retention system. You should ensure that this is adjustable in the rear cradle.

The helmet must be shaped ideally to hug the base of the skull to prevent the helmet popping off the front of your head when you hit the back of it.

D. Things To Consider 4 : Padding and Visors

Padding is just as icing on the cake. It provides you maximum comfort. You can find adjustment of internal shape due to padding in a helmet. This is also highly helpful for wicking away sweat from the head. The anti-bacterial treatment in padding helps to prevent unpleasant smells.

Visors protect your eyes against the glare of the sun.

It also helps to prevent raindrops getting on your glasses or in your eyes. But, you should ensure that they do not obstruct your vision. Visors are not so useful for road bike helmets.

But, it is more applicable to helmets for mountain bikers. If you select a helmet with adjustable visors, you can check how much they protect your eyes.

E. Other Considerations

Crash replacement is the other important factor while selecting a mountain bike helmet. Subsidized replacements are offered by many suppliers. If the helmet damages your lid within the first year or two, a crash replacement will be highly beneficial. You should consider it if you are particularly accident prone.

You should not use strong chemicals or solvents to clean your helmet because they can damage the outer shell & can use mild soap and warm water to clean your helmet.

You can take out pads to wash with  strictly avoid exposing your helmet too high temperatures. If you maintain your helmet properly, you can use it around eight years.
