The Bones Caballero SPF skateboard wheels resist flat spotting on smooth surfaces and offer a higher rebound for quicker response and a faster roll. On top of that, Steve Caballero totally skates these in his own personal pool. Truth.
Narrow - Narrow wheels have the least amount of traction and are intended for advanced, tech riding.
Smooth - Smooth wheels have less surface friction than treaded wheels and are easier to slide.
Skatepark Formula (SPF) - Skatepark Formula wheels are made from a high quality urethane that was specifically formulated to resist flatspotting on slick or smooth surfaces while maintaining a higher rebound for a quicker response and a faster roll.
SPF wheels have a high resistance to abrasion without compromising hardness and slide ability. Skatepark Formula wheels grip better on slick surfaces and are almost impossible to flatspot.
104a - Essentially some of the hardest wheels in the game. Designed for advanced skating and made to withstand flat-spotting, which can result from excessive sliding with softer durometer wheels. Designed for hard-charging, fast skating in mind.
Standard durometer scale of measurement. Most urethane skate wheels generally range from 75a-101a, the numbers increase with the hardness of the wheel.
Made in the USA - All Bones and Powell wheels are made at their factory located in Santa Barbara, California.
