The Roex wheel is Undercover :). It comes from the same factory as the famous Materia brand. Arguably they are the fastest and most durable wheels in the online world, the universe and the galaxy.
We recommend these wheels for all types of urban skating. They are not the best for skids due to their incredible rebound, but for the same reason they are the best for long distances and intensive use.
These wheels are 80mm 88A which means they are extra fast and durable.
The wheels come in a pack of 4 wheels.
