Anyone have an original DuraAce inner chainring for sale? 39T preferred but will buy 42T or smaller. Needs to be usable, but need not be NOS. This is for my early 70's Flandria which appears to be a replica of the DA equipped team bikes of the era. It came with a 52-45. Fine for Freddy Maertens, I suppose, but I need something a bit lower.
