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.
Stone Ground - Stone ground wheels slide much easier than smooth wheels right out of the box. Stone ground wheels don't have an initial break-in period like smooth wheels, and offer predictable slides without having to wear down the wheel surface.
90a - A versatile wheel best used for rougher terrain like craggy streets, ditches or pools or even masonite and metal ramps. Hard enough that sliding is still doable while soft enough for a smooth roll and plenty of grip. Great for beginning park riders until they gain the control needed for harder durometers.
Most urethane skate wheels generally range from 75a-101a, the numbers increase with the hardness of the wheel.
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.
