These Speedrings Ricta skateboard wheels come in white, with black and gold branded detail on the side. These Ricta wheels have a 52mm diameter and a 99a hardness rating, making them ideal for street skating. They have a slim profile for less drag and a medium width for smooth, reliable slides. The lightweight cored design encases the bearing in urethane like a standard wheel so that it maintains shape and allows you to roll away from tricks with speed.
