Can you static balance with wheel bearings only?
Harbor Freight and other have static balancing machines that are basically just a set of bearings with an axle so that the wheel will spin so free that it can be balanced.
Seems pretty easy to make one if you have the centering washers to hold the wheel, but another option would be to just life the bike and spin it in place. The issue would be if the wheel bearings are free enough to allow a small weight to move the tire.
Anyone know where you can buy those centering spacers that are used on the HF balancers?
