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.
SBA Formula - SBA is the original formula, it's super firm for precise skating.
97a - 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 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.
