In the early 1970s, Frank Nasworthy started to develop a skateboard wheel made of polyurethane. The improvement in traction and performance was so immense that the popularity of skateboarding started to rise rapidly again, and companies started to invest more in product development. Many companies started to manufacture trucks especially designed for skateboarding. As the equipment became more maneuverable, the decks started to get wider, reaching widths of 10 inches and over in the end, thus giving the skateboarder even more control. Banana board is a term used to describe skateboards made of polypropylene that were skinny, flexible, with ribs on the underside for structural support and very popular during the mid-1970s. They were available in a myriad of colors, bright yellow probably being the most memorable, hence the name. Manufacturers started to experiment with more exotic composites, like fiberglass and aluminum, but the common skateboards were made of maple plywood.

The skateboarders took advantage of the improved handling of their skateboards and started inventing new tricks. Skateboarders, most notably the Z-Boys, started to skate the vertical walls of swimming pools that were left empty in the 1976 California drought. This started the vert trend in skateboarding. With increased control, skateboarders could skate faster and perform more dangerous tricks, such as slash grinds and frontside/backside airs. This caused liability concerns and increased insurance costs to skatepark owners. Many skateparks went out of business and were torn down. By the beginning of the 1980s, skateboarding had died again.
