The Spitfire Formula 4 Lock-In 99a Wheels are an asymmetrically shaped wheel designed for more control. A conical cut on one side with a straight edge cut on the opposite built for precise lock in grinds.
The amazing new Dragon Formula™ (DF) Urethane used to create these wheels is another industry leading innovation from Powell Peralta. DF-93A Dragons will not only roll over rough terrain, but also grip and slide like 99A and 101A wheels do.
The Formula Four Conical Full skateboard wheels feature Spitfire's performance urethane that lasts longer and withstands more abuse than the competition.
