Trucks: Pivoting axle made of sturdy aluminum that holds the wheels and supports the deck. Ollie: The most basic skateboarder trick.

Vert Course: Ramp setups such as those seen in Tom Petty video ''Free Fallin.' '' Longboard: Basically used for transportation and not tricks, and are popular near beaches.
