Wheel Profile

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.


Smooth - Smooth wheels have less surface friction than treaded wheels and are easier to slide.

Key Features

Formula Four Urethane - Unmatched abrasion resistance for fewer flat spots. More controllable grip. Lasting speed no matter the terrain. Smooth anti-slick slide and a longer lasting size and shape.


Classic Shape - The #1 shape in skateboarding worldwide - features a slim riding surface for speed and control.


99a - Best used in pools and parks with a little more grip than harder wheels, and a little more slide than softer wheels. Ideal for moderately skilled riders who also want to skate street when needed. Hard enough that sliding is a breeze while soft enough for a smooth roll and plenty of grip.

Most urethane skate wheels generally range from 75a-101a, the numbers increase with the hardness of the wheel.
