Sptifire Formula Four Radials 93d Skateboard Wheels - 58mm Size:58mm Undercarriage KitThe Formula Four urethane has had a revamp and is now available in a new 93a hardness. These are referred to as a "Soft Slider" and offer a more gentle roll with a softer ride that allows you to roll over rougher surfaces with ease, whilst still not compromising the slide and feel of a hard, street wheel. These come in the radial shape with a wide riding surface and rounded cut for a consistent slide and grip with minimal slip, unless you want it.
