Drop some wicked style into your setup with Spitfire's Formula Four Pedro Delfino 54mm 99a skateboard wheels! The 54mm diameter provides excellent middle-of-the-road range, and will keep your setup fast and fully flippable, while the 99a durometer can powerslide and pop over any bumps and limps in your path with equal ease. Graphics of a trio of gun-wielding, hazmat-wearing people decorate the wheels, with Pedro Delfino's name spelled out above them in the fiery sky, lending the wheels plenty of post-apocalyptic steez.
