SPITFIRE FORMULA FOUR UNA TRINITY CONICAL FULL 52MM 97D (Set of 4)

Keep your setup quick and controlled with the Spitfire Formula Four Una Trinity Conical Full 52mm 97D skateboard wheels. Featuring Una Farrar’s Trinity graphic, these wheels combine a compact 52mm diameter with a wide riding surface for technical street skating and skatepark sessions.

Spitfire’s Conical Full shape uses a cutaway profile to reduce weight while maintaining a broad contact patch for stability. The 97-durometer Formula Four urethane offers a slightly softer feel than Spitfire’s 99D wheels, with dependable grip, controlled slides, and resistance to flat spots.

• Formula Four urethane: Built for lasting speed and abrasion resistance.

• Conical Full shape: Wide riding surface with a cutaway profile for control without unnecessary bulk.

• 52mm diameter: Compact sizing for a low setup and responsive feel.

• 97 durometer: Balances grip and slide with a slightly more forgiving ride than harder wheels.

• Una Trinity graphic: Una Farrar signature design.

• Sold as a set of 4 wheels.
