I have a vintage lopro bike and would like to identify the frame maker, the serial stamped on bottom bracket starts with "DA" and is then 4 numeric digits, I was told it may have been used in the Olympics/commonwealth 1988 or 90's.

    This is basically impossible there is no central database of frame numbers or even of frame numbering schemes. Oct 4, 2020 at 7:32

    If you don’t provide a photo, this task is utterly impossible and the question will be closed. I’m sorry to be cranky, but these questions are hard even if you show a photo. Do read this: bicycles.meta.stackexchange.com/questions/1337/…

    @user3129787 have a read of bicycles.stackexchange.com/questions/32872/… Basically the serial number is useful to the manufacturer, and for tracking warranty by the shop. Its useless to the user unless you know the brand AND that brand used some kind of decodeable system, which some did and some didn't. Without knowing the brand, serials are not helpful. BUT PLEASE post a picture - if it was an olympic bike in use at Seol, someone will recognise it.

    Cinelli BB shells were used by lots of frame makers, so that isn’t much help. If the multi colored paint job was original you might be able to find photos indicating what country’s team it was
