Bones Wheels M41548

Skatepark Formula (SPF) is a 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 without 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 wheels 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.
