These wheels feature the classic OJ Super soft urethane (78A) but are a slightly smaller size compared to the original 60mm super juice wheels. this means you can run these on a deck with no risers and not have to worry as much about wheel bite. These are an awesome all-around great wheel for cruising but not designed to perform tricks such as slides or grinds as this can pull and rip the urethane.  A quantity of 1 is a full set of 4 wheels.
