catalogue
Skis were invented in northern Europe in the early 20th century to increase the speed of skiers while skiing. Because of the continuous progress of technology, snowboards have been divided into many different kinds.
When choosing the length of the ski, the longest should not exceed the height of the wrist on my arm, and the shortest should not be shorter than the crotch. Choose a long relief ski, the use of speed, good stability, short ski speed is slow, easy to tremble, poor stability.
skis
Mostly the base is
Plastic material
Made. One of these two bases is melt plastic, the other is extrusion, melt plastic is first melted and then cut, they have a long life and easy maintenance. But the moulded skis are the slowest and the least waxed. Extruded skis are the opposite, they are ground into powder, heated, pressed and then cut into shape. Compression plates are better than solute plates, stronger, faster, and better waxed. But it is too expensive to repair.
If you are after excellent performance, then you should choose a extrusion board. If you are on a tight budget, you can also choose a plastic ski.
Another type of ski is better than pressed, called graphite board, graphite board is the fastest of all skis, the largest amount of wax. Graphite base is made of polyethylene, in
Plastic particle
Add graphite to it, and then form a plate. Such boards are usually dark black, and are generally graphite boards that can be seen in speed skating competitions.
It's the part that turns up slightly when you place the board on a flat surface. The size and flexibility of the arch are closely related. The higher the arch, the greater the pressure on the head and tail. A very flat arch indicates that the steering of this plate is flexible, so it is suitable for some freestyle movements. For a used board, a flat head also means that the board has been in use for too long. For most new skis, choosing a slightly curved arch will help you steer flexibly at high speeds and even on very hard snow.
These points are in direct contact with the snow, but are not subject to human pressure. These points are also known as base wheels. Usually near the head and tail. If you put the ski on a smooth surface, put a piece of paper under it, and drag the paper, it will be very smooth and easy to drag in the center, until you reach these points, the paper will stop.
This refers to the metal edge of the ski. The front is called the toe edge and the back is called the heel edge.
The part of the edge of the ski that touches the snow is the part that works when turning, called the effective edge. The front and back sides are not included. The effective edge will be in contact with the snow during the big turn. The longer the effective edge, the more stable and easy to control the glide. While the effective edge is short, the steering is flexible.
This point is usually at the joint of two boards. This point is usually at the beginning or end of the turn. Allow the skateboard to contact the cut line of the snowfall radius. Hard twist points can be good control of snow and ice, on the other hand, a softer board can make the board more stable, suitable for beginners.
For beginners, too long skis are not easy to control, turning is more difficult, and it is not conducive to improving their technical level. According to my experience, it is best for beginners to add about 5 centimeters to their own height. Since the specifications of the ski are based on 5 cm, the selection should be based on the actual situation, such as 170 cm height, 175 cm board length should be selected. And 173 cm height, should choose 180 cm board length. The elasticity of skis is large and small, beginners should choose a ski with greater elasticity, because this ski is not easy to bumpy when it encounters the uneven snow surface, the braking effect is also better, and the operation is easier, so that beginners can quickly master the basic skiing methods.
Good skiers can choose a longer, less elastic, and slightly heavier ski, which can increase stability in sliding, so that the metal edge of the ski is tightly stuck on the snow surface, which is conducive to the skier to fully manipulate the ski and slide out of a beautiful arc. The material of the ski base plate is mainly plastic or polymer
nylon
Made of materials, the friction coefficient of the bottom plate of the polymer material is small, which is better than that of the plastic bottom plate. The edge of the ski should always be sharp, so that when you apply gravity to it, it will not cause a side slide. Professional skiers are said to use skis with edges that shave.
skis
Before the ski maintenance operation, the ski must first be fixed with the workbench and the jig. The table is divided into many grades, and the fixtures are also divided into alpine ski fixtures, simple ski fixtures and veneer fixtures.
Once you've secured the skis, clean the skis. Use a scraper to remove dirt and excess wax from the surface of the board, or use fibers
nylon
Brush and copper brush, wax removal to use special wax remover, and finally with a soft cloth or strong adsorption paper to wipe the ski.
If the bottom of the board is broken, it needs to be repaired. In the past, patch plate and steel scraper were generally used for repair. The new technology is high temperature hot pressing patch plate, and special hot pressing rubber strip is used.
The steel edge on the side of the ski edge is a vulnerable part. To repair the steel edge, first grind the damaged vertical and transverse edges with a diamond file, and then use a fine steel file for processing.

Waxing the skis is a measure to maintain the performance of the skis, and special snow wax is used. There are many kinds of snow wax, according to the temperature of the snowboard use environment, snow quality (new snow, old snow, dirty snow, icy snow, rough snow), air humidity and other conditions as well as the different selection of alpine board, veneer snow wax, there are also suitable for all temperatures and snow quality of fast wax. Snow wax is divided into liquid and paste, ski resorts and ski shops wax with an iron, waxing from the head to the tail of the board, and sometimes polishing with wax. High-grade snow wax is classified into hydrocarbon snow wax, low fluorine snow wax, high fluorine snow wax, perfluorine snow wax.
1. Type of skis:
Before you buy skis, you must understand that the board will be divided into roughly three types (all-around board, park board, alpine board), mapping several aspects of the board and terrain (gyro, jump, U slot, flat style, BOX, RAIL, alpine). The first is also the most common called FREESTYLE (all-around board), this ski is used more in the country, relatively all-around in all aspects have a good performance, speed and hardness medium, the best all-around board is in the rotation, jumping, U slot. The second is called PARK (park board), this snowboard can let you comfortably soak in the park for a day, the common park board has a two-way board (TWIN TIP), the speed is relatively slow, the softest hardness, more suitable for flat style, BOX, RAIL. The third type is called FREERIDE (mountain board), which is generally a long, wide and thin board head, and a short, narrow and thick board tail, which is the fastest and hardest ski.
2. Basic parameters of skis:
(1) LENGTH: attribute English name LENGTH, in general, the longer the board is more stable, suitable for high-speed sliding, the shorter the board is more flexible, suitable for the use of parks and props. But in what range is the appropriate length? Stand the board up, no higher than your nose and no lower than your shoulders. Strictly speaking, the general beginner, it is recommended to use your height minus 20cm is appropriate, according to your weight and preferred play can float up and down 3cm, the weight of people who prefer sliding can choose to float up, the weight of people who like to play flat BOX can choose to float down. If you are an enthusiast, that one ski is not going to meet your needs, you need at least two skis, one for high-speed skiing such as big jumps or mountains that require speed, and the short one for parks and props. The shortest length used to do prop movements, around the shoulders is appropriate. According to the use of skis in foreign countries, in fact, the height of the board and the height of the relationship is not particularly close, the key is to control your weight, as long as your weight in the snowboard can withstand the range, you can use a short board experience the flexibility of the board, you can also use a long board experience speed and stability. This is not necessarily according to the rules, there are 180 players abroad have 152 boards.
(2) Width: Width has three types of attributes, Nose Width (board head width), Tail Width (board tail width), Waist Width (board Waist width), generally we are mainly concerned about Waist Witdth (board waist width). Generally speaking, the board selected according to the height is basically suitable in the width, but some players with large feet may find that the long enough board is not wide enough. The standard is to see whether there is too much of the wide surface of the board after the fixed device and boots are placed in accordance with the customary Angle, for example, the 5 foot fingers are outside, the board is not wide enough. It is easy to have an accident when sliding because it cannot use the edge of the board normally. Note, however, that boots and retainers slightly wider than the board are perfectly normal. If you're a 190cm tall man with a 45 size foot, you're going to need a Wide board to play the BOX.
(3) Hardness: hardness is also a key choice when choosing a veneer. In general, the harder the board at high speed is more stable, suitable for speed maintenance. The softer the board, the easier it is to FREESTYLE, and you should choose different hardness depending on how you like to slide. Body weight also plays a big role in choosing different hardness types. People of the same height, the heavier the relative should use the harder board, and the lighter you can choose a softer board. The general board company has indicated its suitable sliding method and the weight of the player and other standards on the different products launched, we should pay attention to reference when choosing. Because different companies have different standards for different models. Here's a reminder: Whether it is a soft board or a hard board, the real good board is delicate and smooth when pressed on the ground, and if it has a rough and dry feeling, it must not be a good board, and there is a good board pressed up different positions will have different hardness, if you press a board feeling from the board head to the board tail hardness is completely the same, Then the core structure of the board basically no special design, the reason is very simple, you press a piece of plywood will have the same effect.
(4) Plate SHAPE: The translation of plate shape is not very accurate, mainly the shape and length of the fingerboard head and tail. The foreign English attribute is called SHAPE, and there are three parameters: Directional, Twin and Tapered. For the Directional design, the Directional fingerboard head is long and the tail is relatively short, and the standard directional is used for Freestyle (all-purpose board). A Tapered board is a directional shape such as a wide head and a narrow tail. A Freeride board is usually a tapered board. The Twin is not the TT (Twin Tip) bidirectional plate head we often say, which refers to the consistent SHAPE and length of the plate head and the tail. Only when the parameters of the shape attribute and FLEX attribute are both Twin, is the real TT (Twin Tip) bidirectional plate head. This type of board is generally used in Park (park board). However, the standards of each manufacturer are different, so there are a lot of mixed parameters, such as Directional Tapered, Directional Twin, True Twin, Almost Twin, etc., but if you are familiar with the three basic parameters of the plate shape, these combination parameters you can naturally understand.
(5) Elasticity: The English attribute is called FLEX, which is mainly used to describe the hardness and elasticity of the board head and the board tail. The FLEX attribute mainly has two parameters: Directional and Twin. For Directionnal, the thickness of the fingerboard head and tail is not the same, resulting in different elasticity. Generally speaking, the FLEX attribute of Freeride (mountain board) will be such a parameter; For Twin, the head and tail of the fingerboard have the same thickness and thus have the same elasticity. This parameter is generally used for all-purpose boards and park boards.
(6) Effective side length: The English name of the property is EFFECTIVE EDGES, which is easy to understand, that is, the length of EFFECTIVE contact between the blades of the skis and the length of the Freestyle on the EFFECTIVE EDGES is smaller, and intuitively speaking, the Freestyle board looks more convex and convex curves. Freeride is flatter. The goal is for Freestyle boards to have fewer side lengths in contact with the snow than Freeride boards, so players can do more BUTTER and turn around without getting out of control because the effective side length is too large. The Freestyle board has a longer EFFECTIVE EDGE, which makes the sliding more stable and powerful through the larger contact length with the snow, and the turning can be very fast and accurate. The effective side length of some parks designed purely for iron poles is also relatively long, in order to improve the stability of various props.
(1) Board CORE: the English attribute name CORE, the board core is mainly made of different wood, Fiberglass and fiberglass
Carbon fiber
(Carbon) produces different ski performance through different arrangement positions and staggered levels, which is the most critical factor to determine the performance of a ski, which mainly determines the weight, elasticity and hardness of a board. Each major brand names different levels of board core, from weight increase to elasticity decrease. The core of a board can make your Ollie feel like a fish in water, or it can make your jump weak. Too many brands launched bamboo core snowboards in response to the call for environmental protection, in addition to environmental protection, there are not too many highlights.
(2) Board surface: For the board surface is not a beautiful pattern so simple, some brands use anti-slip coating, such as StepChild, some brands are easy to scratch such as Burton and FLOW’
(3) Board bottom: the board bottom material of the major snowboard brands is not the same, but it is mainly divided into two kinds, one is called the extruded board bottom, which is relatively soft, the speed is naturally relatively slow, but the maintenance and repair is more convenient, generally suitable for Park (park board); There's also something called
Sintered plate
The bottom of this board is relatively hard, fast, but relatively difficult to maintain and repair, generally suitable for Freeride (mountain board). In addition to these two, there are many kinds of hybrid plate bottoms, which determine the different speed and wear resistance of the ski.
(4) Blade: there are roughly two kinds of blade for the blade of the veneer from the material, one is the steel blade, the strength is greater, more durable, for Freeride (mountain plate) and Freestyle (universal plate), the disadvantage of the steel blade is difficult to grind, the need for professional personnel and tools; Another material is copper blade, this blade is relatively soft, the corresponding life will be shorter, more suitable for playing various props in the park, there will be no Rail card blade, copper blade grinding comparison. There is also the internal edge, or no edge, which is basically not widely recognized, and Burton's Dominant Slide is embarrassing for us, and it turns out that it has been discontinued.
