I also have an old 1970s Stronglight titanium bottom bracket that I originally bought back in the 70s. I have been searching on ebay for a few months for a comparable one to see what it is worth, but I have not been able to find one. Is it a rare one? I'm guessing that it is. Is anyone interested in talking about it on the list or care to compare theirs with mine?
Best,
