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 ...

Aggressive skate wheels are usually between 54 and 72mm, while anti-rocker wheels are between 40 and 47mm. The balance between hardness and grip is the key to an optimum skate wheel. Anti-rocker wheels are small, hard wheels designed for grinding rather than rolling.
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 skates with a two-by-two wheel arrangement similar to a car.
The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters.
