Formula Four Performance Urethane lasts longer, withstands more abuse and performs superior to all other wheels. Designed to combine all the desired properties of a performance wheel without sacrificing any one attribute at the expense of another.

Manufactured using a 100% pure urethane compound, with higher rebound for faster speeds over rough and smooth surfaces with a hard durometer for a smoother, faster ride that won't mush out over time. Designed with an exclusive anti-stick compound that gives a fast/consistent, smooth slide all the way through.

The Conical Full is a wider version of the Conical Shape. Wide riding surface, cut in sidewalls to decrease weight. A solid, controllable shape for all terrains. These wheels measure 48mm x 30mm with a 99A Durometer.

Wheels come in a set of 4 and include a Spitfire Sticker in the shrink wrap.
