• This wheel can simply be driven by a 1/2" hex axle, with no hub or bearings needed. However, if you wish to drive this wheel with an Axle and Hub, you can pick your hub by fitting any of the AndyMark hubs to this wheel. Hubs are NOT included in the price of the wheel. If this is your choice, then no bearing is needed. To install a hub onto a 6" Performance Wheel, use Hardware Kit 3.

• One sprocket on one side: To drive this wheel with a sprocket, (or to drive another wheel with propulsion from this wheel) then the sprocket needs to be attached to the side of the wheel, outside of a 250 Sprocket Spacer. Use Hardware Kit 3, which includes the screws for this.
• Two sprockets, one on each side: One side of the wheel has no recess, so that side will only need a 250 Sprocket Spacer to space the sprocket out from the wheel. In order to put a sprocket on the other side, use a 550 Sprocket Spacer to get the sprocket out far enough so that the chain clears the edge of the wheel.
