Skatepark Formula (SPF) is very high quality urethane specifically formulated to resist flatspotting 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 flatspot, 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.

Product Performance
Many skaters assume the performance and quality of skate wheels are all the same. A wheel is a wheel is a wheel, they might often say. That's actually not the case. In fact, very large differences exist between the raw materials, manufacturing process, quality control and performance of different wheel brands. Up until now though, a wheel's reputation has been a combination of market hype, market muscle, skater support and word of mouth. Bones wheels popularity is largely a result of superior quality, performance and durability.
Real Value
BONES may not be the lowest-priced wheel, but our abrasion test chart shows why Bones is the best value. After all, what good is a cheaper wheel if it flat spots the first day? BONES wheels offer the best combination of product performance, durability, quality, and customer service available today. In other words, you might be able to find a lower price, but never a better value.
