I have a few options, some more problematic than others. Finding a French size Cinelli or 3ttt may be the most difficult. On the easiest side, I have a friend who's a long-time frame builder that reamed out the steerer tube of my 83 Gitane to fit a standard stem size. At this point, all options are open, including using the original.
