Wide - More traction and stability at high speed so you'll be less likely to slip out of your line.

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

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.

Radial Full Shape - Wide riding surface with round edges for stability and versatility.

97a - Offers more grip than harder wheels and more slide than softer wheels. Great for beginners wanting more control on smooth surfaces or for filmers looking for a smooth roll.
