The Spitfire Formula Four Conical Full Wheel is a wider version of the conical shape, offering a wide riding surface with cut-in sidewalls to decrease weight. It's a solid, controllable shape built for all terrains, finished in a firmer 101D durometer for a faster, harder-rolling ride. Measuring 52mm with a 32.5mm width and 21mm riding surface, it's finished in Red. Part of Spitfire's Formula Four lineup, it's a dependable pickup for anyone after a wider, all-terrain skate wheel with extra speed.
