April 3rd 2009 Durometer A scale is used to calculate the hardness
Durometer A scale is used to calculate the hardness of Skateboarding Wheels. Starting 75a to 99a this scale represents increase in the hardness of the wheel. You may as well see skateboards marked 100a or high, but don’t be fooled ” the A scale just goes up to 99. Street skateboard wheels like Girl Skateboard Wheels are normally very hard, which allows them to slow down quickly and gather power as you go along. This makes it right for tricks and jumps. The comparable is true with vert wheels, which are normally used on ramps, uphill, and upward curves. Softer wheels provide greater maneuvering and speed control, making them just right for slalom racing and long boards.
