Spitfire F4 Una Trinity Conical Full Wheels - 52mm 97D

The Spitfire Una Trinity Conical Full Wheels - 52mm 97D - Natural are Una Farrar’s signature pro wheels, built with Spitfire’s Formula Four urethane and the wider, stable profile of the Conical Full shape.

The 97D Formula Four compound is formulated for a softer, faster ride than harder Formula Four options while maintaining the controlled slide, grip, speed and flatspot resistance Spitfire Formula Four is known for.

Spitfire’s Conical Full shape is a wider version of the standard Conical, using a broad riding surface with cut-in sidewalls to reduce unnecessary weight while maintaining stability and control across street, park and transition terrain.

At 52mm, the wheel measures 32.5mm wide with a 21mm riding surface, giving it a solid contact patch while keeping the overall diameter quick and responsive for technical skating.

Finished in Natural urethane with Una Farrar’s Trinity graphic, this pro model combines a softer Formula Four compound with one of Spitfire’s most versatile full-width shapes.
