ABOUT SKATE PARK FORMULA™ (SPF)
Skatepark Formula™ (SPF) is a very high-quality urethane specifically formulated to resist flat-spotting on slick or smooth surfaces while maintaining a higher rebound for a quicker response and a faster roll.
Skatepark Formula™ has a high resistance to abrasion while not compromising hardness and slide ability. Simply put… Skatepark Formula wheels grip better on slick surfaces, are almost impossible to flat-spot, and are the fastest, longest lasting wheel on the market today.
You won’t find our Skatepark Formula from any other wheel supplier so get a set and find out for yourself what the word on SPF is all about.
