Spitfire Formula Four Skateboard Wheels - O.G Classics - 99 Duro

The Spitfire Formula Four OG Classics are built around a slightly wider riding surface with cut-away sidewalls, striking a balance between stability and reduced weight. The OG Classic shape offers a familiar, predictable feel underfoot, with enough contact for control while still releasing cleanly when sliding. Poured in Formula Four 99a urethane, these wheels roll fast, resist flatspots, and hold their shape through heavy use, making them a dependable option for street and park skating where consistency matters more than novelty.

Key Features:

• Durometer: 99a Formula Four for fast roll and predictable slide
• Urethane: Spitfire Formula Four for consistent wear and flatspot resistance
• Shape: OG Classic with a slightly wider riding surface and cut-away sidewalls
• Ride feel: Stable and controlled with a familiar, all-around response
• Sold as a set of four wheels

Ride the legacy. Ride Spitfire.
