Developed by Frank Nasworthy in 1973, the Cadillac Skateboard Wheel was the first urethane skateboard wheel. This wheel revolutionized skateboarding and has set the standards for all skateboard wheels to date. Cadillac wheels have resurfaced as a staple longboard and cursing wheel. Like the original Cadillac wheels, these wheels have a square profile and a soft compound for maximum performance. Sizes available are 56mm, 65mm and 70mm. Also, new to the line are the Cruisers. The Cadillac Cruiser is an offset 70mm wheel designed for freeriding and riders demanding a wider wheel.
