Spitfire’s well established Formula Four urethane joins forces with the OG Classics shape to deliver skaters the ultimate conical wheel! Start burning spots the original way with 53mm Spitfire OG Classics. The Spitfire OG Classic wheels are 99A durometer and a retro inspired shape with cutaway design that rips, looks cool, and protects the graphic! The OG Classics are a great throwback to a few decades back so they would look dope on a popsicle or a shaped board. With a 53mm size, these are perfect for beginners and riders skating street, skateparks, bowls and vert ramps.
