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.

Narrow - Narrow wheels have the least amount of traction and are intended for advanced, tech riding.

Surface

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.

Shape

Radial Shape - Round edge design for control, speed and a responsive slide.

Durometer

101a - Essentially some of the hardest wheels in the game. Designed for advanced skating and made to withstand flat-spotting, which can result from excessive sliding with softer durometer wheels. Designed for hard-charging, fast skating in mind.

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

they're spitfire so they're fire, I just didn't like them because I prefer a smaller wheel for less weight and wheelbite, I skate 49ers now, can't complain with the quality of spitfire, I didn't slip out even on my little bearing cover 49mm

I really like these wheels. I got the 101 duro 56mm. I've had them for 6 months and they are still good. I'm getting another set because I recently bought bearings and want to have new wheels to skate with them.
