The (solid) axles have slight play in them, as otherwise they would bind slightly and feel a bit scratchy. The rear hub is quieter than the front, but still has noticeable noice when spun fast. The front hub is the worst, and is much louder than the hubs on other bikes in the garage - including one that I also repacked myself.

When in the frame, the wheels spin for a long time by themselves and rotate when still so that the valve/reflector are at the bottom. I'm a bit scared to ride the bike in case I do permanent damage to the bearing surfaces!
