Good helmet standards, and how often you need to change your helmet!

There is no doubt about the function of bicycle helmets to protect cyclists' lives. According to the report of the United States highway safety insurance research, 98% of cyclists in the United States die each year without helmets, while those who wear helmets in impact accidents reduce the risk of serious head injuries by 85%. With the increase of hard Cypress oil road and stone road, the accidents of head injury when riding a bicycle also increase. Riding helmet is an essential equipment for cyclists because it can protect the fragile head.

Generally, people who have never had an accident will not realize the importance of good equipment. Many people have an inferiority complex and feel that the equipment they bring is forced. In fact, it is not. We certainly hope that the stronger the protection is, the better. Life is once. You save money on equipment, that is, you spend more money in the hospital. Now, the slightest fracture surgery, It also costs nearly 10000 yuan. Such local savings really outweigh the losses.

So, how to choose a riding helmet? What's the difference between them? Let's take a look at the following.

[about texture] - good density

Helmets are generally made of foamed materials (ordinary or high-density, the difference between which is their anti-collision effect) and have a smooth shell surface.

[about weight] - light

Things pressed on the head can not be too heavy, which is also the reason why riding helmets are not made of alloy materials; Most helmets weigh between 9-16 ounces (1 ounce = 28.350 grams), which is only a pound unit or even lighter! Note: cheap helmets are mostly heavy.

[about lining] - washable

Helmet functions such as washable corduroy fabric or anti microbial liner can keep your helmet clean and fresh. The helmet with excellent workmanship has a large lining coverage, better texture and stronger adhesion with the inner side of the helmet. The Velcro behind the lining can facilitate the cleaning of the lining. Just soak it in the water with detergent or detergent for a few minutes, rub it slightly with your hands, rinse it with clean water and dry it.

[about wearing comfort] - it can adjust the head circumference

Cheap helmets are generally uncomfortable. Helmet fitting is a must. Helmets in bicycle stores are small, medium, large and extended sizes. I'm afraid the cheap helmet is only one size. You know, wearing a comfortable helmet can greatly reduce the pressure on the rider's head and neck, and maximize the protection effect in case of impact.

[about breathability] - feel dry

It can ensure the dryness of your head during long-distance riding. The more vents on your helmet, the greater the airflow around your head and the cooler you feel. Cheap helmets have only a few vents, so they are hot. However, keep in mind that the more vents on the helmet, the more your head is exposed, so the degree of protection is reduced accordingly. It is recommended to wear a "sweat band" on your head in hot weather to prevent sweat from flowing into your eyes. In the cold season, wear "ear muffs" or elastic thin headscarves (called balaklavas) to keep warm.

[about types] - meet the riding needs

Half helmet type riding helmets are divided into special-purpose for highway (without brim), dual-purpose for highway and mountain (with removable brim), etc. Some friends also use helmets similar to baseball or roller skating. The shape of full helmet riding helmet is similar to that of motorcycle helmet, which is generally used by speed or climbing enthusiasts. Therefore, the category you choose also determines the price of helmets to a certain extent.

About the sense of design] - humanization

There are different types of helmets. Some helmets have plastic visors in the front to protect their glasses from the sun and rain on rainy days. It can also prevent the helmet from being stuck on the brim of the helmet when riding at night. The more eye-catching the color at night, the easier it is for cars or other cyclists to see you. (PS: don't think color Dazzle is b)

In addition to the above points that determine the price of helmets, there is another point: in addition to the material cost, there are many factors such as scientific research and development, intellectual property rights, marketing cost, brand premium and so on. The cost performance can not be generalized. At least in the helmet industry, the requirements for technical content are very high, which is much more generous than those luxury goods such as Lv.

To sum up, when selecting bicycle helmets, you should give priority to helmets that meet your needs and are reasonably priced according to the importance of helmet selection. Comfort > breathability > appearance and weight.
