Road Fan is right on the money. As I mentioned earlier, just buy new or nearly new bits that are compatible. Sometimes the corner bends on noodle bars (or Cinelli 64s for that matter) can be a pain, depending on the stem. Just take your time and don't force the piece. They don't need additional stressors, they get plenty on the road. Its really not worth oral surgery. In fact, there was a good thread lately about the Cinelli XA stem. Enough people pointed out they are somewhat prone to failure. I took it off the bike right away, whether I needed to or not. These components are not worth risks, I like riding way too much to have these types of issues.
