Radical Wheels - Purple 56mm 92A Joy Wheel (4 Pack)Radical Joys come in at 92a and 56mm x34mm. While still being small and narrow enough to clear the coping or run grind blocks, these wheels offer a bit more grip for park skaters who might be new to the park. Additionally, the lower durometer can be good for those who want to easily transition between street or park skating without having to change their wheels, or for people who want to be able to dance and jam outdoors.
