slight "wobble" in bike while riding.
I've got a 20 year-old frameset that has a very slight wobble when riding it, very much like an incompletely seated tire or untrue wheel. I've taken my custom built wheels (that run 100% smooth) and put them on this bike and the wobble is still there. Is there some frame misalignment that could account for this? I know for certain the headset is properly adjusted and I don't know about the bottom bracket and if that would even make a difference.
