That is what I gathered from the bit of searching around I did after the bike came up for sale.I know nothing that has not already been shared about gears, chainrings or shifters, (in fact a great deal less!!) but I will add my 2c to say that Diamondback's were great bikes back in the day. I had one as a kid. I think they are underrated/overlooked by a lot of collectors/retrobike addicts...
Sounds like other companies which had a great reputation at one point, like Raleigh when they were made in Wales but through getting sold off they end up selling BSOs and get a bad name.
The story seems a little different with DB in that they were great back then but still underrated due to lack of aggressive marketing that other companies did. No bad thing if the consumer knows this but bad for them as a company.
