A skateboard consists of several key components that work together to provide a smooth riding experience. The main parts include the deck, which is the flat board you stand on, and the trucks, which are the metal parts that attach the wheels to the deck. The wheels are made of urethane and come in various sizes and hardness levels, affecting the ride's speed and grip. Another important component is the bearings, which fit inside the wheels and allow them to spin freely. The griptape is a rough surface applied to the top of the deck, providing traction for the rider's feet. Together, these components create a functional and enjoyable skateboard.
