About Skate Park Formula™ (SPF)

Skatepark Formula™ (SPF) is a high-quality urethane specifically designed to resist flatspotting on smooth surfaces while maintaining a higher rebound for quicker response and faster roll. SPF has high abrasion resistance without compromising hardness and slide ability. In short, SPF wheels provide better grip on slick surfaces, are nearly impossible to flatspot, and are the fastest and longest-lasting wheels available today.

About Durometer B Scale

Shore Durometer A Scale is limited in covering the full range of skate wheel hardness since it only goes up to 100A. Shore Durometer B Scale is perfect for skate wheels because it reads 20 points lower than the A Scale, extending the useful scale range by 20 points to cover the entire hardness range of skate wheels in one scale. It provides accurate readings without puncturing the wheel surface like the D Scale does.
