Spitfire Formula Four Skateboard Wheels - Conical Full - 99 Duro

The Spitfire Formula Four Conical Full wheels build on the standard Conical shape by widening the riding surface for increased control and stability. The broader contact patch gives a more planted feel on landings and at speed, while the cut-in sidewalls help keep weight down and maintain a clean, predictable release when sliding. Poured in Formula Four 99a urethane, they roll fast, resist flatspots, and hold their shape through heavy sessions, making them a dependable choice for skaters who want a stable wheel without giving up responsiveness.

Key Features:

• Durometer: 99a Formula Four for fast roll and predictable slide
• Urethane: Spitfire Formula Four for consistent wear and flatspot resistance
• Shape: Conical Full with a wide riding surface and cut-in sidewalls
• Ride feel: Stable and controlled with confident response on streets and parks
• Sold as a set of four wheels

Ride fast. Land clean. Roll Spitfire.
