Two votes for replacing. Well, if it's not that much then maybe I will replace them. It just seemed like cleaning them might work easier.The bearings in my headset are like I described. I'd like to clean up those in my crank as well and I think they are the same.So if I were to replace all these bearings, I am assuming that they come in different sizes. What should I have with me to make sure I get the right ones?
