I assume that is just because there's more power being applied with the crank arms at say, 8 & 2 o'clock than at 11 & 5 o'clock? Where does the maximum wear tend to be (I can then make a point - ha ha - of checking those spots in particular on my bikes)? And would it make sense (as I think 02Giant was suggesting) to make rotating the rings part of a maintenance routine?
