    How To Choose Suitable Riding Helmet

    Riding enthusiasts on road cars, riding people think that you can go beyond this level easily, let alone professional cyclists, in the high tension competition, often nearly a hundred times of the high speed, but also should go back and ponder carefully: my safety helmet is not safe at all. In the bicycle age, please call Lv Dongfeng, a company's business manager (hereinafter referred to as Daniel) to explain to us:


    Daniel said that in the early days of the safety helmet development, the earliest version was called the "full function cap" before it evolved into a hat style. Lin Daozhong's branches and rocks were blocked. The latter was classified as mountaineering car caps and personalized prisms, with the rise of mountain bikes.


    The rough character of mountain riders is now subdivided into highways, mountaineering, time keeping, leisure and other items.


    The round shape is fitted with the large hat brim, which is a modern version of the helmet for mountaineering vehicle. The round shape is fitted with the large hat brim, which is a modern version of the helmet for mountaineering vehicle.


    The general functional safety helmet is mainly made of olive type, and the rear end is designed with "duck tail", which brings air mechanics and visual effects. However, Daniel emphasized that the more roundness of the design, the smaller the force deviation during the impact, and the stability of the head and safety helmet in the rolling process to avoid neck.


    Because of resistance, the handsome cutting-edge shape, once contacted with the ground, is the source of increased friction.


    The bicycle safety helmet is a large part of the bicycle safety helmet. Daniel, for example, is like aluminum alloy, which is like aluminum alloy. It is light weight and changeable in shape. Between the glue shell and the particle, the thermal protection glue can achieve the bonding effect. The safety helmet of PU material can be compared to the titanium alloy. The processing limit is more, and it is not easy to break in weight and molding. However, the material is conducive to shock absorption, the strength is superior to the former, and the foam itself is sticky.


    Be careful. There are risks in these places.


    In order to achieve lightweight demands, the inside of the dragon will be reinforced by transverse and vertical ribs, which will reach the rigidity of the safety helmet after crossing. However, this material emphasizes density and density, which is directly related to strength. In other words, excessive lightweight safety helmets are not safe.


    "Is my safety helmet safe?"


    To answer this question, Daniel recommends that you carefully examine the particles that are tightly bonded after prebubble. Because of the organic solvents and ultraviolet rays that come into contact with each other, it will damage the bonding of the Dragon cap. Once the cracks or breakages occur, this is the most vulnerable place when stress concentration occurs.


    Therefore, Daniel suggests that knights should avoid putting helmets in the car for a long time and avoid touching chemicals or organic solvents in the air before they can use them safely. Of course, after impact, it is not suitable to continue to use. This concept applies to 2 materials.


    Cracks after long term use are the warning signs of safety helmet aging. Cracks after long term use are the warning signs of safety helmet aging. After the impact of the rear side, there is an obvious crack in the cap. After the impact of the rear side, there is an obvious crack in the cap.


    Attention should be paid to safety first.


    Riding enthusiasts may not know, at present, bicycle safety helmets, regardless of vehicle type, in the domestic inspection standards are the same. With many requests for aerodynamics and ventilation performance of the riders, each brand has been designing with great efforts and constantly changing the main structure of the safety helmet. Even the top hand of the first class motorcade, there are many different views on the head. Even a first-class professional player, the shape of the helmet is dazzling. Even a first-class professional player, the shape of the helmet is dazzling.


    "Compared to equipment, human factors are the biggest source of wind resistance." Daniel said so. In addition to professional cyclists, the choice of general cyclists should start with safety. Notice that wearing a helmet can reduce injury by seventy percent. A good safety helmet is absolutely necessary for riding enthusiasts in the face of danger.
