Deck
- The actual board. The flat, long, oval/rectangular, usually wood part of the skateboard that you stand on. Skateboard decks are classically made from 7 plys of wood, usually maple, laminated together.
Grip Tape
- Grip tape is the gritty, sand papery layer that's applied to the top of a skateboard deck, so that your shoes can grip the board.
Trucks
- Trucks act like the the axle of a car, but for a skateboard. Trucks are the metal T-shaped part that mounts onto the underside of the skateboard deck, that the wheels will be attached to. A regular skateboard will have two trucks, each facing each other.
Wheels
- Self explanatory.
Hardware
- The bolts and nuts that are used to connect the trucks to the deck.
Bearings
- Bearings sit inside the wheel hubs and determine the smoothness of the ride of your board.
