Skateboard
A skateboard is a type of sports equipment used for skateboarding. It is usually made of a specially designed 7–8-ply maple plywood deck and has polyurethane wheels attached to the underside by a pair of skateboarding trucks.
For other uses, see Skateboard (disambiguation).
The skateboard moves by pushing with one foot while the other foot remains balanced on the board, or by pumping one's legs in structures such as a bowl or half pipe. A skateboard can also be used by standing on the deck while on a downward slope and allowing gravity to propel the board and the rider. If the rider's leading foot is their left foot, they are said to ride "regular". Conversely, they are said to ride "goofy" if their leading foot is their right foot.[1]
The two main types of skateboards are the longboard and shortboard. The shape of the board is also important: the skateboard must be concaved to perform tricks.[2]
Parts[edit]
Deck[edit]
"Long" boards are usually over 36 inches (91 cm) long. Plastic "penny" boards are typically about 22 inches (56 cm) long.[9] Some larger penny boards over 27 inches (69 cm) long are called "nickel" boards.[10]
The longboard, a common variant of the skateboard, is used for higher speed and rough surface boarding, and they are much more expensive. "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.[11]
Wheels[edit]
The wheels allow for movement on the skateboard and helps determine the speed while riding.[12] There are typically four wheels on a skateboard that are attached to the trucks. Ranging in size from around 48mm to around 60mm, smaller wheels are lighter in weight and are used for shorter distances and tricks.[13] The wheels are typically made of polyurethane (PU) and come in different grades of PU. Higher-grade PU is more durable and provides a smoother ride, while lower-grade PU is more affordable but wears out faster.[14] Larger wheels are heavier in weight, which are better for maintaining speed and longer distances. Wheels that are larger than 60mm are typically used for longboards.[15]
Trucks[edit]
The metal parts known as skateboard trucks are what hold a skateboard's wheels to the deck. They are made up of a hanger that holds the axle and wheels and a baseplate that is mounted to the board. The hanger and baseplate are joined by a kingpin, allowing the truck to swivel and turn.[16]
Trucks for skateboards come in a variety of forms and sizes and can be modified to the rider's preferences. The truck's height can have an impact on the board's stability and turning ability. The truck's width should equal the width of the deck.
To manage the looseness or tightness of the trucks, the kingpin's tightness can also be changed. This is a matter of taste and has an impact on the board's stability and ability to turn.[17]
Optional components[edit]
Skateboard multi-tool[edit]
While not part of a skateboard, an all-in-one skateboard tool capable of mounting and removing trucks & wheels and adjusting truck kingpins are commonly sold by skate shops.[20]
