Wheel Profile

Medium - Your classic wheel shape, versatile all-around wheel for street/park skating.

Surface

Smooth - Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.

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.

Wheel Shape

Lock Ins Cut - Asymmetrically cut, you can get the benefits of conical outer walls while the inside wall is cut straight, giving you a flat surface to lock in your grinds.

Durometer

99a - Offers more grip than harder wheels and more slide than softer wheels. Great for slick surfaces when you want more control.

Lock-in is no lie. These puppies work. Click, bam, boom... locked. Super smooth. I recommend getting 1 mm size larger than you would normally ride, let the edges round out a little.

Great wheels, I picked up the 55mm 99A and have been really happy. Bigger size, wider contact patch, and slightly softer formula are great for less than perfect sidewalk and streets. would 100% recommend picking these up to anyone.
