Chris Miller knows smooth lines and specializes in making the sketchiest bowls look like child's play, and the Bones Miller Owl SF Skateboard Wheels are what he relies on to make this happen. Featuring Bone's Skatepark Formula™, these wheels offer higher rebound, more slidability and a super high resistance to flat spotting.
Skatepark Formula™ (SPF) This 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. It has a high resistance to abrasion while not compromising hardness and slide ability. Skatepark Formula wheels grip better on slick surfaces, are almost impossible to flatspot, and are the fastest, longest lasting wheel on the market today.
