LOVE SKATEBOARD
Parts
Descriptions of the following skateboard parts are the ones most prevalent in popular, modern forms of skateboarding. Many niche disciplines exist with exotic or alternative constructions and designs that fall outside of much of the descriptions listed. The usual parts to design a complete skateboard are the deck, trucks, wheels, and the bearings. After that is the hardware.
[edit] Deck
The underside of a skateboard. In this photo the deck, trucks and wheels can be seen.Most decks are constructed with a seven to nine-ply cross-laminated layup of Canadian maple. Other materials used in deck construction, fiberglass, bamboo, resin, Kevlar, carbon fiber, aluminum, and plastic, lighten the board or increase its strength or rigidity. Some decks made from maple ply are dyed to create various different coloured ply. Modern decks vary in size, but most are 7 to 10.5 inches wide. Wider decks can be used for greater stability when transition or ramp skating. Skateboard decks are usually between 28 and 33 inches long. The underside of the deck can be printed with a design by the manufacturer, blank, or decorated by any other means. The longboard, a common variant of the skateboard, has a longer deck. This is mostly ridden down hills or by the beach. This was created by two surfers; Ben Whatson and Jonny Drapper. One of the first deck companies was called "Drapped" taken from Jonny's second name. "Old school" boards (those made in the 1970s–80s or modern boards that mimic their shape) are generally wider and often have only one kicktail. Variants of the 1970s often have little or no concavity, whereas 1980s models have deeper concavities and steeper kicktails.
Grip tape, when applied to the top surface of a skateboard, gives a skater's feet more grip on the deck. It is most often black but can come in clear, allowing the top of the deck to be decorated. It has an adhesive back and a sandpaper like top.
[edit] Trucks
A skateboard truckAttached to the deck are two metal (usually aluminum alloy) trucks, which connect to the wheels and deck. The trucks are further composed of two parts. The top part of the truck is screwed to the deck and is called the baseplate, and beneath it is the hanger. The axle runs through the hanger. Between the baseplate and the hanger are bushings, also rubbers or grommets, that provide the cushion mechanism for turning the skateboard. The bushings cushion the truck when it turns. The stiffer the bushings, the more resistant the skateboard is to turning. The softer the bushings, the easier it is to turn. A bolt called a kingpin holds these parts together and fits inside the bushings. Thus by tightening or loosening the kingpin nut, the trucks can be adjusted loosely for better turning and tighter for more control.
Longboard specific trucks are a more recent development. A longboard truck has the king pin laid at a more acute angle (usually between 38 and 42 degrees) to the deck, this gives a lesser degree of turning for the same tilt of the deck. This adds stability and allows riders to go much faster while still maintaining stability and control.
[edit] Wheels
The wheels of a skateboard, usually made of polyurethane, come in many different sizes and shapes to suit different types of skating. Larger sizes like 65–90 mm roll faster, and also move more easily over cracks in pavement. Smaller sizes like 48–54 mm keep the board closer to the ground, require less force to accelerate and produce a lower center of gravity, but also make for a slower top speed. Wheels also are available in a variety of hardnesses usually measured on the durometer 'A' scale. Wheels range from the very soft (about 75a) to the very hard (about 101a). As the scale stops at 100a, any wheels labelled 101a or higher are harder, but do not use the appropriate durometer scale. Some wheel manufacturers now use the 'B' or 'D' scale, which has a larger and more accurate range of hardness.
Modern street skaters prefer smaller wheels (usually 45–53 mm), as small wheels can make tricks like kickflips and ollies easier. Street wheels are often quite hard as this allows the wheels to 'break away' from the ground easier. Vert skating requires larger wheels (usually 55–65 mm) as vert skating involves higher speeds. Vert wheels are also usually very hard, which helps with maintaining speed on ramps. Slalom skating requires even larger wheels (60–75 mm) to sustain the highest speeds possible. They also need to be soft and have better grip to make the tight and frequent turns in slalom racing. Even larger wheels are used in longboarding and downhill skateboarding. Sizes range from 65 mm right up to 100 mm. These extreme sizes of wheels almost always have cores of hard plastic that can be made thinner and lighter than a solid polyurethane wheel. They are often used by skateboard videographers as well, as the large soft wheels allow for smooth and easy movement over any terrain.
[edit] Bearings
Each skateboard wheel is mounted on its axle via two ball bearings. With few exceptions, the bearings are the industrial standard "608" size, with a bore of 8 mm, an outer diameter of 22 mm, and a width of 7 mm. These are usually made of steel, though silicon nitride, a high-tech ceramic, is sometimes used. Many skateboard bearings are graded according to the ABEC scale. The scale starts with ABEC1 as the lowest, 3, 5, 7, 9. It is a common misconception that higher numbers are better for skateboarding, as the ABEC rating only measures tolerances, which do not necessarily apply to skateboards. The ABEC rating does not determine how fast or how durable a bearing used for skateboarding will be. In particular, the ABEC rating says nothing about how well a bearing handles axial (side-to-side) loads, which are severe in most skateboard applications. Many companies do not show the ABEC rating, such as Bones Bearings, who makes bearings specifically for skateboarding. These bearings are usually called swiss or ceramic and are better for skating
