Ten Misunderstandings in the Use of Riding Helmets

1. The lighter the helmet, the better.

Relatively speaking, the lighter the helmet, the better. But the lighter the helmet, the less chance it will pass the national security certification test, and the higher the relative price. So the prerequisite of selecting helmet is to pass the national security certification test standard. Most of the helmet can achieve 260G. This weight won't make you tired even if it's long distance, so you don't have to pay too much attention to the weight index of the helmet. Unless you're racing for a bicycle. To minimize self-weight, otherwise, it is not worth spending extra money to buy a lightweight helmet.

2. The larger or more holes in the helmet, the more ventilated it is.

Air permeability is the key to the helmet, which ensures that your head is dry while riding long distances. The more or larger the vents on the helmet, the greater the air flow around your head and the cooler you feel. Keep in mind, however, that the more or larger the vents on the helmet, the more exposed your head will be, so the degree of protection will be reduced accordingly. Highway bicycle helmet has more or larger ventilation holes than mountain bicycle helmet. Similarly, compared with mountain bikers, road bikers need to consider the weight of helmet. Generally speaking, the lighter the helmet is, the more expensive it is. Therefore, unless you want to reduce your weight as much as possible in order to compete in a bicycle race, it is not worth the extra money to buy an ultra-light bicycle helmet.

3. Small inserts and pulling belts are related to life. If the inserts and pulling belts cannot bear certain forces, they will break.

You may only know that the riding helmet needs some impact tests, but the buckle and pull belt also need to do the corresponding pull test. If they do not pass the corresponding pull test, they can not be used on the helmet. Therefore, a qualified riding helmet, small insert and pull belt must pass the corresponding test, only then can a person truly meet the national security certification test standard of the helmet.

4. Crack or overuse of helmet

If it's cracked, don't use it. If it's worn, it's just a comfort to the heart. It's not of much practical use. If it's a little bump, it doesn't matter. But once it falls, it's powerful, it's not likely to play a protective role. Don't underestimate a crack. It has changed the force and component effect of the helmet in physical structure. Do you know why a bridge collapsed in Seoul in the 1990s? Later, it was inferred that the crack might be caused by a weld joint on one side of the bridge deck that was not soldered firmly. Change the simple principle, you pull a brand new A4 paper from both ends, it may take a little effort to break, but once you tear a small hole in the middle of the paper, it's easy to break the paper.
Whether they have fallen or collided, cyclists should change their helmet every three years. Because, although the helmet has not been collided, sunshine exposure and sweat erosion will also make the helmet and some accessories aging, thereby reducing the safety factor and damaging the helmet protection performance.

5. Wear helmet without tie

It may be more comfortable to unfasten the jaw strap of the helmet, but if the head is hit, it will easily bounce off, naturally without protection. So in order to play the protective role of the helmet, please wear the helmet jaw belt at any time.

6. Wear a helmet too wide or too narrow

If the helmet size is incorrect, it can't protect your head from being hit. Don't make the mistake of buying an inappropriate helmet. To determine the correct size of the helmet, you can first measure around the largest part of the head (usually one centimeter above the eyebrow), and then buy the helmet according to this measurement value. Since helmet sizes are usually small, medium and large, you may only be able to buy a relatively suitable size, and then use the size adjuster rotation button to adjust to achieve the most suitable size. After wearing the helmet, transfer the helmet from one side to the other side, from the front to the back, feel comfortable wearing, if too loose or too tight, you need to continue to adjust or replace.

7. Use inferior helmet

Helmets are manufactured according to strict technical standards, and inferior helmets often fail to meet safe anti-collision standards, which can cause danger.

8. Misplaced

The most effective position of the helmet needs to maintain the level of the helmet and head, and the edge of the helmet should be about 1 centimeter above the eyebrow. If not in this position, check whether the helmet size is appropriate, and then adjust the adjuster knob and jaw strap to ensure that the helmet is in the right position.

9. Loose bandwidth

Loose tie makes the helmet move at any time, and the protective effect decreases when the head is collided twice. Therefore, it is necessary to adjust the length of the pull-belt to make the distance between the pull-belt and chin, and adjust the space to a gap between the fingers, so as to maximize the effective safety protection performance of the helmet.

10. Riding helmet should be released after use.

After each use of the riding helmet, please place it in a cool and ventilated place to avoid high temperature or long sunshine.
