Spitfire Formula Four Classics are built to perform universally well in many scenarios, they will make you experience a sweet balance between stability of a wide wheel and responsiveness of a narrow one! The 97a durometer version slaps crusty spots with power and smoothness, while retaining the signature Formula Four feel.  

Spitfire’s Formula Four Performance Urethane lasts longer, withstood more abuse and performed superior to all other wheels. 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. Formula Four’s True lasting Performance Urethane comes not from a single benefit. However, from a combination of qualities and features that together produce a truly great wheel.

Formula Four Performance Urethane is unlike any other. Formula Four wheels retain more material, coned less and keep their original shapes
and sizes longer than any other wheel.
