A wheel core assembly for a recreational device such as a skateboard is provided. The orientation of the wheel core assembly can be readily reversed to allow use of both sides of a wheel such as e.g., a side-set wheel. The position of an outer bearing and a spacer can be readily switched to either side of an internal chamber thereby allowing the user to select the orientation of the wheel on an axle. The outer bearing and spacer can be configured for ready removal and installation without the use of special purpose tools.
