The Spitfire Formula Four Conical Full 99a skateboard wheels have a larger contact patch. Spitfire released their new Formula Four wheels a few years ago now. The latest formula was designed for higher abrasion resistance. This means it is a little harder to flat spot. Formula Four 101a wheels are generally decorated with a graphic. Unless of course it is one of the signature wheels. The signature wheels feature artwork custom designed for each rider.
