700 bikes … wow - I sold 7 in one year and I thought I was doing well …
what size is your bike ?
I keep an eye open for the PDG road bikes in the smaller (est) sizes - and I have not run across one (but not a dedicated search) … but do have some small PDG MTBs though
yeah top tube should never be clamped - cringe when I see that

my bike is a 54 cm. Over the years i sold a few older Paramounts ,most were 58-62 cm and were 531 tubing. I road the 58 for a while but it was to big. I see a lot of PDG mountain bikes on Facebook marketplace and most are very cheap. Many less than $100. There is a 1990 series 2 pdg 54 cm on Asheville nc for $30. It has been on there for months. It looks like a beater. I see guys on youtube rebuilding bikes held by the top tube . I have never seen a Paramount PDG on Charlotte Craiglist.
