Landing in a 60mm diameter with a semi-translucent neon pink color, Spitfire offers the Sapphires skateboard wheels in a special 90a durometer Formula Four urethane to give a soft, smooth ride that will never flatspot. Small text branding is printed on the inner core of the sidewalls, while a classic "Big Head" logo is hidden within the riding surface of the radial-shaped wheels for an innovative design that adds a futuristic look to your setup.
