The Spitfire Formula 4 Classics feature an unmatched abrasion resistance for fewer flat spots, more controllable grip, and longer lasting speed no matter the terrain.

With a 55mm diameter, these are perfect for beginner and pro  riders skating street, skate parks, bowls and vert ramps. Formula Four Urethane was developed to combine all the desired properties of a performance wheel without sacrificing any one attribute at the expense of another!
