Basics
deck: the flat standing surface of a skateboard, usually covered in grip
tape that provides a place to stand
grip tape: sandpaper fixed to the top of the deck to increase trction/friction between
the skateboard and the skaters feet so they can keep a grip on the board.
nose: the front of the skateboard, from the front truck bolts to the end.
rail: the edge of the skateboard, also, plastic strips attached to the board’s underside.
tail: the rear of the skateboard, from the back truck bolts to the end
trucks: the front and rear axle assemblies, connects the wheels to the deck and allow for turns.
wheels: usually made of polyurethane and sized between 39 and 66 millimeters in diameter;
their hardness is measured by durometer, a number ranging from 0 to 100—soft wheels have a durometer of about 85, hard
wheels have a durometer of 97 or higher
wheelbase: the distance between the front and back wheels, measured between
the two sets of innermost truck holes.
