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.
Quad roller-skating racing is the precursor to the popularity and acclaim received by competitive racing on in-line skates. Up until 1991, all World Championships were held on quad skates. Most events at the 1992 World Championships were specific to quads, however, some events were classed as "open" giving the athlete the option of choosing ...
Freestyle skaters tend to use a mix of hardnesses on skates, using a harder wheel on the edge they need to spin and a softer wheel on the other edges. A typical freestyle wheel will range from 92A–103A or 35D–61D. A softer wheel with more grip is used for dance. Popular quad wheel brands include Roll-line, Rollerbones, Komplex, and Boiani.

Barcol hardness is measured on a scale from 0 to 100 with the typical range being between 50B and 90B. A measurement of 60B is roughly equivalent to a Shore hardness of 80D or a Rockwell hardness M100. [4] [6] As defined in ASTM D 2583 the scale divisions from 0-100 should each indicate a depth of 0.0076 mm or the equivalent 0.0003 inches. [7]
