Modern decks vary in size, but most are 7 to 10.5 inches (17.78 to 26.67 centimeters) wide. Wider decks can be used for greater stability when transition or ramp skating. Skateboard decks are usually between 28 and 33 inches (71.12 and 83.82 centimetres) long. The underside of the deck can be printed with a design by the manufacturer, blank, or decorated by any other means.
2. GRIP TAPE
Grip tape is a sheet of paper or fabric with adhesive on one side and a surface similar to fine sand paper on the other. Grip tape is applied to the top surface of a board to allow the rider's feet to grip the surface and help the skater stay on the board while doing tricks. Grip tape is usually black, but is also available in many different colors such as pink, yellow, checkered, camo, and even clear. Often, they have designs die-cut to show the color of the board, or to display the board's company logo.
Attached to the deck are two metal (usually aluminum alloy) trucks, which connect the wheels and bearings to the 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 stability. Standard kingpin nut size is 3/8" - 24tpi.
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 55–85 mm roll faster, and move more easily over cracks in pavement and are better for transition skateboarding.
