I have a theoretical question that isn't related to any specific problem I'm having, but it occurred to me as I was repacking a hub the other day.
There are numerous threads and articles around describing what bearing precession is, especially as an explanation for why pedal and BB thread directions are reversed on opposite sides of the bike.
My question is, does this effect apply to hub cones on threaded axles? For example, looking at my 105 rear hub from the left side, the hub shell rotates counterclockwise as the bicycle moves forward. If I'm thinking about it correctly, this would result in a slight clockwise torque on the cone. With a right-hand threaded axle, I believe this would tend to pull the cone away from the locknut. Since the only thing holding the cone in place is friction against the locknut, I would think this would create a vicious cycle where that friction force is reduced, leading to more creep in the cone, leading to even less friction, etc., while simultaneously increasing pressure against the bearings (bad).
So, assuming I've got it right, is this ever a problem in real hubs? And if not, why is it a problem in pedals and BBs but not hubs? I would think it would make more sense to use a left-handed thread on the left side of the axle, and vice versa.
