You may notice a discrepancy between what we designate a wide, standard or narrow and what the brands do. This classification is our opinion based on years of skating, as well as looking at the profile of the wheel as it compares to what we believe is a standard profile. You just have to trust us on this.
Wide - Wide wheels provide more traction and stability at high speed, so you'll be less likely to slip out of your line.
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.
84b SPF - SPF's are a hard skatepark formula wheel, designed for a fast roll whether charging the local park or your neighbor's pool. Bones claims that their "b" scale is 20 points lower than your typical “a” scale, meaning the hardness of the Bones 84b SPF Formula would in turn equal a 104a in hardness which would be beyond the limitations of the “a” scale.
