Providing unmatched control and lasting speed, the Spitfire Formula Four Conical Full Skateboard Wheels were designed to have a wider riding surface and cutaway. Made with a smooth riding surface in a wide profile, these wheels are sold as a set of four in a variety of sizes and durometers.
Smooth - Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.
Wide - More traction and stability at high speed so you'll be less likely to slip out of your line.
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.
Conical Full Shape - Wider riding surface and cutaway design for unmatched control and lasting speed.
