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.
Standard - Your classic wheel shape, it's not built to excel in specific scenarios like a narrow or wide wheel, but it's appropriate for most situations. If you're new to skating this is where you want to start.
Treaded - Treaded wheels provide improved grip and traction on smooth surfaces.
Street Tech Formula (STF) - Street Tech Formula wheels are specifically engineered from top quality components to obtain all the best properties necessary for the ultimate in street wheel performance.
Street Tech Formula wheels have a substantially higher rebound for more speed and amazing slide capabilities while maintaining a resistance to flat spotting well beyond any standard wheel. The technology behind STF is proven, ask anyone who's shredded on 'em.
STF V2 Shape - This shape features the narrowest surface area available coming in 4mm narrower then the standard Mini-Rat Shape, this means reduced weight and friction for improved sliding and technical performance.
83b STF - STF's are a street tech formula wheel but can handle the park just as well. Hard, fast and smooth. Bones claims that their "b" scale is 20 points lower than your typical “a” scale, meaning the hardness of the Bones 83b STF Formula would in turn equal a 103a in hardness which would be beyond the limitations of the “a” scale.
This is the riser size we suggest using if you want to avoid wheel bite, essentially the larger the diameter of the wheel the more likely you are to get wheel bite if you don't add risers of this size to your complete, so the larger the wheels the larger the riser required.
