This parameter affects the overall feeling of an allegro: the longer the wheelbase, the more stable the feeling, but the slower the speed; Or vice versa, the wheelbase from Dallas to the auditorium is usually about 50cm, and the wheelbase of freestyle board is only about 40cm; Boss, 55-80 cm.

2. An available skateboard is usually made of 7 layers of sugar maple. There is a smooth layer of special chemicals at the bottom of the smooth board.

3. Foot socket refers to the curved concave part on the chessboard. In addition to freestyle boards, all popular boards now have foot sockets, which is also for skateboarders to better control skateboarding.

5. In the past, the most popular wheel size was 60-70mm, and the freestyle wheel was usually 57MM. Generally speaking, a big wheel is good for maintaining speed and passing through small obstacles, but the acceleration is not as fast as that of a small wheel and it is too heavy. Small wheels are suitable for playing skillful movements.

6. Hardness is usually measured by Shaw A coefficient of Shaw Company. The greater the value, the greater the hardness. Generally speaking, the wheel hardness is inversely proportional to the rebound, and the hard wheel is faster, but the road surface is too bad. 95A wheels can also perform well on slightly poor ground.

7. The standard of bridge body is that the distance between two wheels on the same bridge body after installation cannot be greater than the width of the board (at least the same), otherwise it will affect the turning and action of the board.

8. Pedestal refers to the part where the bridge contacts the board surface. After numerous tests, aluminum alloy has been proved to be the best base material.

9) The main screw is used to combine the axle shaft with the base (PU pad is provided at the joint).

9. The main part of the main bridge is used for sliding when doing actions such as 5050.

Second, the history of skateboarding

Skateboarding started in California in 1950. The earliest skateboards were made of skates (fixed on the board). Skateboarding is very popular because of surfing: in fact, skateboarding was originally called "sidewalk surfing". Initially, skateboards were made by individuals with boards and boards by hand. With the popularity of this sport, the company began to produce skateboards on 1959.

In postwar America, society was carefree, and children usually played in the street. While the company strives to make the board of directors lighter, stronger and improve its performance, the board of directors is also developing.

Skateboarding is a very personal activity. Skateboarding continues to develop. Since 2000, skateboarding has become the mainstream due to the attention of media and products such as skateboarding games, children's skateboarding and commercialization. With more and more interest and money invested in skateboarding, more and more skateboarding parks and better skateboarding came into being.

In addition, continuous interest urges skateboarding companies to innovate and invent new things. Skateboarding will appear for the first time in the 2020 Summer Olympics.
