Cone and Cup Hub Maintenance
I have a cone and cup type hub and had questions about the bearings. I read that cone and cups usually have 9 bearings in the rear per side and that they are supposed to be flush with the cup. My bike has 9 per side but they don't lay flush in the cup. When I take one out (8) they all fit and sit nicely with a little space left from the missing bearing. To clarify, if I put the ninth bearing in, it pushes and slighty elevates the rest of the bearings in order to fit. I'm sure all 9 bearings level out with the even pressure of the cone on them, but their bottom won't be in contact with the cup, just their sides. I've tried both the 8 and 9 setup and they both seem to run smoothly, I'm just wondering if not having all the bearings fully seated will wear them out quicker, or visa versa. And a little off note, I have a wax type lubricant and was wondering if I could use that instead of grease for the bearings. Thanks.
