The Envy Delux wheel is sold individually, comes in at 120mm in diameter, 24mm wide at the core, but 26mm wide at the urethane. The increased width is designed to make your grinds more consistent as it puts extra distance between your wheel's core, and the obstacle that you're grinding. This wheel will fit any fork that is capable of fitting 120mm wheels and is a must have if you're looking to add some color to your setup.
