Evolution history of skateboard wheel?
Skateboard wheels are usually made of polyurethane. The wheels have different diameters, shapes and hardness. With the progress of science and technology, skateboard wheels are more and more advanced. What is the evolution history of skateboard wheels?
Boutique skateboard wheel
1955: the skateboard wheel first appeared in the United States, which was disassembled from the iron wheel of roller skates.
1963: "sidewalk surfer" composite plastic wheel, 50X30mm, 86g, 90a, improved from the wheel and pulley, is the first commercial mass-produced skateboard wheel.
1973: PU wheel appeared for the first time. It was made of industrial forklift tire material. PU material makes skateboarders avoid side slip when turning rapidly, making it the midwife of modern skateboarding.
1976: instead of "loose beads", precision bearings were specially used for skateboards. Wheels are often designed with large "lips" to increase adhesion. 58x70mm，167g，90a。 1977-1983: the "white bone" wheel of the patent of soul Ao appeared. Features of the wheel: high rebound double arc edge, high rebound polyurethane material with * * property is used, which can roll faster, have greater adhesion, and no longer rely on the huge "lip". The double arc edge is helpful to overcome obstacles and rotate flexibly.
1985: ramp wheels: cabrero began to use harder wheels on smooth ramps and pool surfaces to better control adhesion. Diameter and weight are reduced to improve acceleration and reaction speed.
1988: vertical wheel: with larger diameter and smaller width, it is optimized for half pipe ramp. The height used by the hawk to impact the vertical slide.
1989: Street wheel: "street type (road type)" * * emphasizes reducing the weight of the wheel, low center of gravity and smoothness.
1992: Street wheel: the diameter suddenly decreased and the hardness increased, which evolved for a variety of road style movements.
The evolution of skateboard wheel represents the innovation of material science and the development of skateboarding. The evolution history of skateboard wheel represents the development history of skateboarding.
