Protecting the head during riding is very important, but it is often overlooked by many knights. As a result of cycling, a large number of cases of bloodless sacrifice due to wearing or not wearing helmets occur every year. There are skin traumatic injuries, internal injuries, broken clavicles, broken arms and legs, and loss of life. However, this did not cause enough caution to the knights. According to the BHSI survey in the United States, about 700 deaths caused by riding in the United States each year account for 70% of head injuries. There are also statistics showing that an ordinary rider will experience an accident every 7200 km of riding. When the author goes out riding, he always sees that there are many riders who do not wear helmets to ride. This is basically streaking! In the event of an emergency, regret it! We remind everyone here that we must have enough safety awareness of the activities we are involved in, be responsible for ourselves and be responsible to our family members.
Helmet is essential equipment for riding! Helmet is essential equipment for riding! Helmet is essential equipment for riding! Three important things to say! It is not an exaggeration to say how many times.
Since the helmet is a necessity, picking the right helmet is a top priority. There are many bicycle helmets on the market. The price ranges from tens of dollars to two or three thousand. There are various styles. How can we choose? How to buy a suitable helmet? I combed it from several aspects.
The safety of the selection of riding helmet material - this is the primary consideration for our helmet purchase! Where does the security come from? One is the material used for the helmet and the other is the design of the helmet science. Helmets that look the same, may have poor protection performance. Recommend that you choose those brands certified by the standard safety standards of bicycle helmets, such as Lightning, TREK, Giant, Bell, Giro, and Kask, and other large brands, and many domestic counterfeit products suggest that you abandon! While we hope to ride faster and faster, the safety standards will also increase. Everyone does not want to let those cottage products without any R&D and design investment protect the most important heads, which is too risky. The products of these big brands are guaranteed, and the design of materials and safety used is higher than that of a mountain helmet.
The big-name helmets are all safety-certified, such as the Kask helmets, which are certified through bicycle helmets in the three markets of Europe, the United States, and Australia (CE, CPSC, and AS/NZS respectively). Only through these certifications can the products be Related market sales, this is the confidence of security. The domestic cottage helmets are many, many are not certified through safety, especially those less than 100 yuan cheap products.
The material of riding helmets has been legislated for cyclists to wear helmets in many areas in foreign countries. The non-green area is shown below.
The shape of the choice of riding helmet shape - helmet is divided into two types, there are two main, one is oval, one is round. The former is suitable for Europeans and Americans, and the latter is suitable for Asians. When Asians wear oval helmets, there is a sense of chucking on both sides of the head. We use a round helmet, its profile can better fit our head type, wear compact, to provide maximum security. In this regard, I still recommend Kask because the Kask helmet is a round design with a thicker inner liner that can better match a wide variety of head contours and is more compact and comfortable to wear. The two images below show the wearing effect of the elliptical and round helmets at a glance.
Ventilation Ventilation of Cycling Helmet - The ventilation of the helmet is very important, especially in the hot summer, you definitely do not want to wet the top of the head while riding, even the sweat will flow into your eyes (the riding cap will be very Useful). A helmet of good quality will have an air slot between the top of the head and the helmet, creating an air flow between the two to help dissipate heat. Of course, ventilation is sometimes not the first choice because, like the Triathlon/TT helmets, ventilation is sacrificed because of considering the aerodynamic performance first and the number of holes is small.
The tightening system of the riding helmet is the tightening system of the riding helmet - that is, the device behind the helmet which can be adjusted in size. This is related to the wearing safety and fine tuning of the helmet. The tightening system should be able to fix the helmet on the head well without shaking, so that it can work in an emergency situation; the quality of the belt and the connection with the helmet are also considered indicators. In addition, a good tightening system can be adjusted in both horizontal and vertical directions to better match the helmet to the head shape.
One thing that needs to be mentioned here is the adjustment of the vertical direction. Many of the helmet's tightening system is tied to the bones behind the head. It's not right. There is a prominent part of the hindbrain, which is the hindbrain bone, and the tightening system must work under its hoop. This is the advantage of the helmet with adjustable vertical direction. According to different head types, it can be adjusted up and down, and it can always be hung under the hindbrain bone. For example, the vertical bar in the middle of the helmet is used to adjust the vertical position.
The chin strap is also part of the tightening system. Be sure to buckle your chin while riding! Wearing a helmet without a chin is equal to not wearing it because the helmet will come off in an emergency!
The weight of the helmet - the weight of the helmet depends on the materials and technology used. The lightest road helmet currently on the market is about 220 grams. In general, the better the helmet, the better the material used, the more reasonable the structure, and the lighter the weight. But not the lighter the helmet, the better the quality. First of all, most of the helmets are made of foamed foam. A good helmet will use two layers of inner and outer foams of different densities. How these two layers of foam are connected is also responsible for the different price points. A good helmet is to make two layers of foam. Cross-fusion, the structure is stronger, the appearance is more beautiful, and the difference is simple bonding, even using only one kind of density. And the bubble itself is also good or bad. Just think about the difference in helmet weight. In addition, a good helmet has a built-in skeleton, just as there is a reason to use steel bars in the building. There are two types of carbon fiber and polycarbonate, the former is more expensive and the latter is lighter. These are the reasons why the weight of the helmet is different, and they are the main reason for the price to be pulled out.
As can be seen from the above two figures, the two types of bubbles are fused in one figure, and the two figures are fused with obvious gaps. A picture shows that the helmet is being processed together with the outer shell and the overall strength is much higher and more beautiful.
When it comes to materials, there is a small trick when buying helmets. As shown in the picture below, the two helmets actually have a big difference. The blue circle on the left side of the helmet is the outer shell of polycarbonate. It can also be understood as a plastic shell. It covers the foam inside, and the foam on the right side of the helmet. It is directly exposed. What's the problem? The foam is easily squeezed, pits appear, and it is easily dirty, while the plastic shell does not allow the surface to be pitted, prolonging the service life and allowing the helmet to be updated.
The back of the helmet of the mountain helmet protects the back of the mountain helmet. The protection of the mountain is more complicated, so the protection is more demanding. The protection of the hindbrain is particularly important because it is very fragile and vulnerable. For mountain helmets, covering the hindbrain is an additional item. At present, the mainstream XC-grade mountain helmets have the protection of the hindbrain, and the shanzhai products have almost no role in this respect. This is where the value difference is.
In summary, the helmet's breathability, aerodynamic design, internal structure, shape coating, and the use of materials have brought a variety of advantages and disadvantages, while the helmet has hidden costs in all these aspects, so that the cheap cottage What exactly is a helmet? How much is the design and R&D expenses for such a low price? What material is used? How is the breathability? The most important thing is that there is no guarantee of security? Please see the officer's own judgment.
Attach the correct helmet-mounted schematic and wear it correctly to achieve a good safety effect. The following figure shows the steps of wearing a helmet. Note the position of the second step, do not block the line of sight, do not leak too much on the forehead. The tightness of the four or five steps should be appropriate. Too loose is insecure. Wearing the effect is not the same as the sixth step. It is not safe.
Finally, I share my point of view:
1, buy brand helmets. Brand products are guaranteed in all aspects. A one-off investment is not only an improvement in safety performance, but also an increase in forcing. Wearing a cottage is not always the case.
2, on the price - the ability to do it. Brand selection, the difference in price is the difference between weight and aesthetic appearance, of course, this is the minimum requirement, involved in aerodynamics, or see the money to speak. When it comes to price, there is a point to be made that is to determine the price of the helmet based on the price of its own vehicle. Some people say that my car is only 5000 yuan. Buying a helmet of a thousand or two is too luxurious. It is better to upgrade a part. My point is that the head is the most important, and you can't overdo it if your conditions permit. The threshold of the hospital is much higher than the threshold of the helmet.
3, which brand? See what you like, which one you like, haha. I am Kask's powder because I like Team Sky and I like Made in Italy. The quality abroad is not the same and the workmanship is good. Many other brands are made in China. It is very comfortable to wear, before wearing Giro, collet! Changed kask much better.
Finally, my friends remember riding a helmet and riding happily!
