Autism, like skateboarding, can be unpredictable and oftentimes unruly. We embrace the parts of autism that are hard to understand and give these kids an outlet that is free of rules or judgement, while allowing them to be social.

The Blue wheel represents Autism and our commitment to help create an outlet for kids who are affected by this disorder. Thank you for your support.

Shore Durometer A Scale is good, but it does not cover the entire range of skate wheel hardness and is very limited because the scale goes from 1 to 100 and anything over A 95A does not compute accurately.

Shore Durometer B Scale is perfect for skate wheels because:

  1. It is very similar to the A Scale, but reads 20 points lower, allowing the useful scale to be extended by 20 points, which covers the entire hardness range of skate wheels in one scale. It uses the same soft spring as the A Gauge, but the conical gauge needle of the D Scale.
  2. Because the spring is soft, the B Scale gauge needle does not puncture the skin of the wheel surface, resulting in the same reliable reading as the A Scale does.

Shore Durometer D Scale is designed for hard rubbers and rock hard urethanes, not soft, bouncy urethanes that are used in skate wheels. It has a very stiff spring behind its sharp conical needle and often punctures the skin of the wheel being measured, this resulting in 5-10 points softer reading than is correct. Thus, Shore D Scale should not be used for wheels in the useful skate wheel range.
