Parts of SkateBoard

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, bearings, hardware, and griptape.

Deck

Most decks are constructed with a six to seven-ply cross-laminated layup of Canadian maple. Other materials used in deck construction, such as 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.

Trucks

Attached 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.

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 54–85 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.
