Does anybody know the exact size of the bolts for this stem? I want to replace the steel bolts, not really for weight savings as much as getting rid of the rust prone steel bolts. While they are coated with a black coating, some of the coating is starting to wear off and developing some surface rust. I want to replace them with Ti bolts but want to make sure I order the exact size I need.
