Hubs are NOT included in the price of the wheel. If this is your choice, then no bearing is needed. With Sprocket: If you wish to drive this wheel with a sprocket, then the sprocket needs to be attached to the side of the wheel, and two ball bearings need to be pressed into the wheel (one on each side). The ball bearing must have a 1.125" od. With Bearings: Wheels can be driven by 1 hub or they can ride on up to two bearings. The center bore is sized to receive a 1.125" outside diameter flange bearing (FR8ZZ or am-0573) on either side in a press fit manner. These need to be purchased separately.
