Skateboard frame
Seemingly simple
Actually ... it's very simple.
How do novices choose the skateboard that suits them? First of all, we should understand the structure of a skateboard, and then consider what kind of skateboard to choose, no matter which part or brand, the most suitable one is the most correct way! The following battalion commander can explain the structure of a skateboard, and can basically remember the structure by decomposing a picture!
Generally speaking, skateboard is composed of the following parts: skateboard is mainly composed of plate, sandpaper, bracket, PU, wheel, bridge end nut, bridge nail, buffer pad, bearing and so on.
support
The bracket with wheels is the most durable part of the skateboard. You can use it to grind all kinds of surfaces. They can transform you. You know they're important, right? Let's take a look at the composition of the bridge: it consists of the shaft sleeve/shaft, the main nail of the bridge, the bushing and the bottom plate.
The base plate is the part fixed on the board surface. The thick screw passing through the bottom plate is called the kingpin. You can adjust the tightness of the pivot pin to control the flexibility of the bridge.
The main nail is the most easily damaged part of the whole bridge, but it can be replaced. Bushing is above the main nail, and each bridge has two bushings, one large and one small, with different hardness. With your use and abuse, they will break, and then your bridge can't be tightened. Fortunately, many bridge manufacturers offer replacement sleeves with different hardness.
One problem with the bracket is "shaft slip", which occurs when the plate hits the ground with its side and the shaft is perpendicular to the ground (the term is primo). The shaft slides in the shaft sleeve so that one wheel is tight and the other wheel is loose. The general way to deal with this situation is to primo the board in the opposite direction, but it is conceivable that the problem of sliding shaft will only get worse after a long time. Many companies claim that their bridges are "anti-skid". You can have a try.
Don't listen to others say whether the bridge is tight or loose. It all depends on your preference. A loose bridge is easy to turn, but a tight bridge is more stable. You can also tighten the rear axle slightly, so Ollie is more stable.
Bridges have different widths. A bridge too wide is installed on your board and looks like a turtle. When you turn the chessboard, the bridge will touch your feet. The narrow bridge prevents you from seeing the wheels when you slide. One principle of choosing the width is to erect the side of the plate after the bridge is installed, so that it can be placed basically vertically on the ground. So you can do something like somersault.
wheel
Wheels are a neglected part of your skateboard, but wheels determine how you feel when you skate. It depends on where you skate-street, U-pool, swimming pool or indoor cricket field-which will determine what kind of wheels you choose (including size and hardness). When you face all kinds of wheels in a skateboard shop, you will drool. You may think that they just look different and use the same, but you are wrong.
When selecting wheels, color and pattern may be important factors, but function is more important. Wheels are made of polyurethane, which is a chemically synthesized hard rubber. Improve the performance of wheels by changing the proportion of chemical components.
The first is hardness. Skateboard wheels are usually made of polyurethane, and the hardness of the wheels varies with the proportion of polyurethane in the wheels. Wheels with hardness of 85A(A stands for hardness) are soft, suitable for sliding on rugged roads, and the sound is extremely low when sliding, which is a good choice for friends who like to pedal shopping. However, the wheel of 85A is soft and not wear-resistant, and it is easy to break the spacer when doing sideslip braking and other actions.
Generally, skaters choose 97A- 103A wheels. This kind of hard wheel is suitable for smooth marble and flat road surface, as well as props such as U pool and platform jumping. There is no sound in smooth and flat places, such as the wheels of 85A. But in rugged places and on the U-shaped pool, there will be a loud rumble (this kind of sound often makes the wrench have a boiling blood). 103A is not recommended for transparent or translucent wheels. It's too hard and will crack. It is best to use it only on props made of all wood materials.
The second is the diameter, and 38-40mm wheels are rarely used. This kind of wheel accelerates quickly, but has little stamina. It is only suitable for very flat roads, and its characteristic is quite flexible. Friends who like small moves can try.
45mm-50mm wheels are the most suitable wheels for road types. 52-60mm wheels are more suitable for props. Because the action on the props needs strong power, the flat action wants the board to be as light as possible, and the heavy board on the props can sometimes bring greater inertia and impact, allowing you to fly higher and farther. You can choose cross-country wheels over 60 mm in the field, and professional mountain skateboarding uses large rubber wheels.
There is also a rebound, and the rebound of the wheels is very important. Although there are no parameters to refer to. However, the stronger the rebound, the stronger the ability to overcome obstacles. If you don't know how well your wheels bounce, you can do a small experiment. Remove the bearing from the wheel. You throw the steering wheel to the ground hard. If the bullet is high, the wheel will bounce to the ceiling. If the wheel bounce is low, it will only bounce on the ground twice. On the flat ground, perhaps, the two kinds of wheels run as fast, but when encountering uneven road conditions, the advantages of high rebound wheels will immediately appear.
Hardness:
87A- Very rough ground (steep slope, etc.). )
95A- Rough ground (block)
99A- Smooth floor (various markets, skatepark, U-shaped pool, swimming pool)
10 1A- Not suitable for rough or very smooth ground (poor grip because it is too hard).
Size:
52-55mm- Suitable for most users. Market, skateboard park. Little skater.
56-60mm- Suitable for most users. Market, skateboard park. Adult skater.
60+mm- special skater. Lengthening the board, downhill, mud.
Novices had better choose wheels with lower hardness, because they can't control their skateboards well to avoid pebbles, glass and debris on the road. If the hardness is too high, these fragments will jam their wheels, while experienced skaters usually choose harder wheels.
If you are a beginner, you'd better consult your friends or try several wheels with different hardness and size to help you make a decision.
Professional skateboarding should be bought in a professional board shop. Most toys sold in shopping malls and sporting goods stores are toy boards.
face
1, generally made of five-layer, seven-layer and nine-layer maple boards by microwave cold pressing. There are also aluminum alloy, carbon fiber and other materials of the board, board, board head, board tail are inclined.
The board surface above 22cm can basically be regarded as the board surface of U pool, and its board can accommodate more feet and is more stable on U pool. 19cm boards are mostly used for flat road conditions. The sub-plate can move flexibly and quickly after being equipped with small wheels.
In addition, boards designed by different companies have different footwell depths. Some skaters like the board with deep footwell, which makes it easier to make the action related to turning the board and is more stable when doing Ollie.
abrasive paper
1 piece, adhered to the upper surface of the board to increase the friction with the sole and facilitate the control of the skateboard.
bearing
Eight, each wheel is equipped with two precision bearings. Bearings have different precision and durability. Generally speaking, bearings have an ABEC mark, ranging from ABEC- 1 (the least accurate) to ABEC-7 (the most accurate).
However, some bearings do not have the symbol of ABEC. For example, bone bearings have never had the ABEC logo, but their bone Swiss ceramics are one of the best skateboard bearings.
1. What skateboard should a novice buy?
Toy board, toy board refers to a skateboard that is only for sliding, and beginners can also use it. Beginners should choose a flat skating rink and wear elbow pads, wrist pads, knee pads, helmets and other protective gear when skating. Beginners are suitable for choosing toy boards.
Professional board, which every real skateboarder should know and be familiar with, is your ultimate career and will accompany you from now on. Because skaters have to do all kinds of difficult movements, tricks and even strange ways of playing, the strength and performance indexes of all parts of the professional board should meet the requirements of use.
2. Precautions for skateboarding
Adjust the wheels before use to make them run freely. The elasticity of the buffer pad should be reasonably adjusted with the lock nut according to its own use. Oil the bearing regularly to increase the lubrication of the bearing and reduce the sliding resistance. Beginners need to slide on the slopes with small inclination with the help of relatives and friends, and gradually change different slopes with the improvement of technical level. Don't slide on wet or uneven roads. When you want to jump off the skateboard, observe whether you can bump into people or other objects around you.
3. the benefits of skateboarding
The design principle of scooter is more in line with the growth of teenagers. It is based on the theory of human motion and ingenious mechanical principles, and mainly uses the twisting of waist, buttocks, feet and the swinging of hands to drive forward. Skateboarding can exercise children's will quality. As a beginner, it is a process of constantly honing inspiration from the beginning of falling failure to the final successful sliding mastery. It can make children more confident, brave and persistent, and greatly exercise their will quality.
Basic structure of skateboard
Wheelbase: the distance between the front and rear wheels. 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, 55-80cm. The board surface is usually a usable skateboard made of 7 layers of sugar maple. There is a smooth layer of special chemicals at the bottom of the smooth board. Foot socket refers to the curved and concave part of the board. In addition to freestyle boards, all popular boards now have foot sockets, which is also for skateboarders to better control skateboarding.
Because most of the existing boards are double-tilted (the boss and son are easy to separate), they look similar. Generally speaking, the head of the board is longer than the tail of the board, and sometimes the angle is larger. In the past, the most popular wheel size was 60-70 mm, while the freestyle wheel was usually 57 mm. Generally speaking, a big wheel is good for maintaining speed and passing through small obstacles, but the acceleration is not as fast as a small wheel, and it is too heavy. Small wheels are suitable for playing skillful movements.
How to play skateboarding?
Skateboarding is a sport that requires high physical quality, especially the balance, coordination and dexterity of people. In order to better adapt their bodies to "life on the board", most skateboarders in the world use a fitness equipment called "Indian board" for training. This "Indian plate" is actually very simple, that is, a flat plate is installed on a cylindrical wheel. Through training, people can improve their balance ability, and at the same time, they can fully exercise related muscles and maintain the stability of their bodies.
For skateboarders, keeping weight is an important link. Excessive size and weight will seriously affect their dexterity. Burnquist's method is to use moderate and light weights to do strength exercises, while in family gym training, Burnquist himself invented doing squats, abdominal muscle training, and even playing solid balls on the "Indian board". When training on the ground, Burnquist usually improves his flexibility and dexterity by practicing yoga. In aerobic training, he often uses indoor cycling, which can effectively protect his knee joint.
Skateboarding is very suitable for beginners, and there is no restriction on gender. Both boys and girls can play it. Double-warped skateboard is specially used for technical movements, which is divided into board head and board tail. The double-warped skateboard has four wheels, all of which are very flexible. It is easy for a novice to keep his balance with a pair of upturned skateboards. If you learn well, you will soon learn a series of movements!
Walking in the street or on campus, you will always see some people. Their skillful movements and handsome appearance attracted everyone's attention. If you think life is boring, then join us in skateboarding! Both men and women can play skateboarding. Everyday life is so boring, buy a skateboard and move. Cool and handsome!
