Proto UFO Rear-Wheel Adapters

UFO Wheel Adapters allow you to ride any wheel on your PROTO TDI Deck. Because TDI has been Standardized since its inception, UFO Wheel Adapters are compatible with every TDI Deck so you can ride any Wheel with any PROTO Deck ever made. They are available for both 24mm & 30mm wide Wheels as well as 8mm & 12mm diameter Axles. Wheels which require 12mm Axles can be adapted to use the Standard 8mm Axle with no additional components or modifications by using the appropriate UFO Wheel Adapters.
