Originally, decks 🤑 were made of wood, but later they were also made of aluminum, fibreglass, and plastic.
The rear part of the deck 🤑 is bent upward to form the kicktail, as is the front ("nose") on modern designs.
The truck includes an axle, a 🤑 hangar (which houses the axle), and a cushion that both absorbs shocks and provides flexibility for steering.
