Skateboarding is the originator of the history of extreme sports, and many extreme sports are extended from skateboarding. Skateboarding originated from surfing in the late 1950s and early 1960s, and now it has become the coolest sport on earth. Skateboarding skills mainly include: air (on the slider), inversion (on the U-shaped platform) and Ollie (take off with a board). These skills can be said to be the most important skateboarding action besides turning over. Two important international skateboarding organizations in the world: International Association of Skateboarding Companies (IASC) and World Cup Skateboarding (WCS).
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.
There are five skateboarding techniques: street, pool, half pipe, freestyle flat ground and downhill. Street style is also very popular, with many fans and excellent players. Swimming pool fancy and semi-tube are merged into vert. Flat freestyle has been lost for a long time! There are also some skiers, and then another kind of sled appeared, that is, lying on a long sled with four wheels and brackets to play downhill, which is much more exciting than skateboarding.
Types of skateboards
Toy board
Toy board refers to a skateboard that is only used 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. However, if you are really determined to start your extreme life, then put down your children's board!
Professional Committee
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.
There is little difference between street type and U-shaped pool type, expressway type and downhill type. The U-shaped pool slab is wider, the bridge is softer, the expressway slab is very long (in fact, the expressway slab has independently developed into another sport, referred to as long slab), and the downhill type has higher bridges and pneumatic tires.
primary structure
The skateboard is mainly composed of board surface, sandpaper, bridge (bracket), PU, wheels, bridge end nuts, bridge nails, buffer pads and bearings. No matter which part, no matter what brand, it is the most correct way to choose the one that suits you best! Remember, it's for you, not for skateboarding, which will determine your style. How to choose a skateboard that suits you? This requires you to accumulate skateboarding knowledge slowly and do a lot of exercises at the same time.
Performance index
wheel
When selecting materials, we should consider that they are suitable for different site pavements, such as floor pavements, cement pavements and asphalt pavements. No matter what road surface you slide on, the wheels must have good elasticity, wear resistance and moderate hardness, and also ensure that the wheels have sufficient friction coefficient on the road surface. (Generally, the hardness coefficient of a wheel has three units: A, B and D. Because some materials and indicators are different, it cannot be accurately converted. )
Buffer pad and sleeve
It mainly plays the role of cushioning and shock absorption. One is to play a damping role when the road surface is uneven; The second is to protect the parts when the amount of exercise is large; The third is to keep your body balanced.
face
Generally speaking, it is made of Canadian maple laminate, and the pressing process is divided into cold pressing and hot pressing. Cold pressing is to directly compress sawdust without adding glue, which is more advanced and has better performance. The board has high strength, high impact toughness and good elasticity, which ensures that the pedal will not be damaged when jumping on a skateboard with a certain height.
support
Bracket, which we call "bridge" for short, is the skateboard accessory that bears the most torsion, extrusion and friction in the whole skateboard. Bridges are generally cast in alloy, and the technology and design of each brand are different. Bridges can be divided into three types: high, medium and low, and the length of the central axis of the bridge also matches the width of different panels.
Skateboard parts
It is very important to choose the right equipment for skateboarding. Skateboarding is made up of several different parts. Due to the different terrain and mode of skateboard, the parts are also different. Generally speaking, skateboarding consists of the following parts:
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, different companies have different depths of slabs and footpits. 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.
bridge
Two, made of metal, are fixed under the board and the wheels are mounted on the bridge. The bridge can turn the wheel and adjust its rotation speed and angle.
Bridges play an important role in the performance of skateboards. Bridges produced in the United States are mostly special aluminum alloys, and almost no longer break. Spans of skateboard bridges are 126 mm, 129 mm, 134 mm, 139 mm, 146 mm, etc. Skateboarding bridges with different spans and boards with different widths make skateboarding more flexible and easier to control. The height of the bridge is also different. The higher bridge is suitable for installing larger wheels, and the lower bridge is suitable for installing smaller wheels, so it will be more comfortable to slide, and it is unlikely that the wheels will hit the board when bending or the main bridge nail will break due to excessive bending.
Indy, Venture, Destructo, Thunder, Orion, Grindking, Titan (Nissan) and other bridges are all good. Indy is known as the king of bridges, and its quality is self-evident. There are also quite a few people using VENTURE in America. DESTRUCTO is the best-selling bridge in America and my personal favorite bridge. DESTRUCTO is very smooth when doing the action of sliding bridge on the round bar (such as 50/50, 5/0, K-GRIND, etc. ), and it is very stable. Orion's PU cushion is so good that it can be as hard as a stone when twisted, and it won't explode no matter how you use it. GRINDKING's bridge is the lightest, but the steel bar in its central axis is not very hard, it will bend if it jumps too much, and it is not wear-resistant, but its main bridge nail is quite good, and it is reverse. Titan, according to friends who have seen it, is very good, beautiful, lightweight and rust-proof, but it is a little more expensive than ordinary bridges.
loose pulley
Fourth, polyurethane material. Wheels come in different diameters, shapes and hardness. The small boat starts fast, but it lacks stamina and is suitable for skills; Big wheels are easier to slide on uneven ground.
Skateboard wheels are also very particular. Except the accuracy of bearings (such as ABEC 1, ABEC3, ABEC5, ABEC7, etc.). ), it depends on the performance of the wheel.
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 slammed the wheel to the ground. 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.
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.
The first thing to do is to choose the board. Skateboard is generally composed of board surface, skateboard bracket and skateboard wheel, which is also a high cost part. A good skateboard generally needs its own configuration. There are some accessories such as bearings, sandpaper, screws and other small items.
