Two inline skate wheels with different durometer – 85A and 83A Digital Shore hardness tester. The Shore durometer is a device for measuring the hardness of a material, typically of polymers. [1] Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer ...
Like wheels, bushings are available with different levels of hardness. The kingpin nut may be tightened or loosened to adjust the turning radius and response of the truck itself. Tighter bushings mean stiffer trucks and less chance of "wheel bite", where the wheel makes contact with the deck, damaging the deck and slowing or stopping the wheels.
Urban skates Hockey skates. Inline skates are boots with wheels arranged in a single line from front to back, allowing a skater to roll along on these wheels. Inline skates are technically a type of roller skate, but most people associate the term roller skates with quad skates, another type of roller skate with a two-by-two wheel arrangement similar to a car.
A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels.
The following is a list of notable companies that produce skateboards and skateboarding merchandise. Companies listed may also be members of the US -based trade association , the International Association of Skateboard Companies and may have skateboarding sponsorship arrangements with individuals, venues or events.
Typical longboard wheels range from 65 to 107 millimeters (2.6 to 4.2 in) in diameter. A taller wheel will have slower acceleration but a faster rolling speed. Smaller wheels have the opposite effect. The durometer of a wheel is how hard the urethane is. A softer wheel will be ultimately slower than a harder wheel on smooth surface.
They tend to last well, but can be easily damaged if used outdoors. Wheels for outdoor use are softer with a durometer of 82–87, and tend to wear more quickly. Harder outdoor wheels can also be used effectively indoors. Skaters sometimes combine different hardness wheels on the same skate in an attempt to achieve the best combination.
But Nasworthy’s discovery was the catalyst for the second skateboard boom. As a professional freestyle competitor at the time noted: The progress of the urethane [sic] wheels just totally stoked me; you could do so much more on a skateboard, surf moves, especially; you could carve your turns and stuff without sliding, that changed everything ...
