Bones Wheels - Forever Young - SPF - White/Red - 55mm (set of 4)
All BONES® WHEELS unique formulas are solely developed and produced in our own manufacturing plant located in Santa Barbara, CA. Using drastically different physical and engineering properties for each formula, BONES creates unique urethanes for specific applications of skateboarding.
Skate Park 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.
SPF also has a high resistance to abrasion while not compromising hardness. SPF grips better on slick surfaces, is hard to flatspot, lasts longer and rolls faster than the competition.
