Single Speed Peuguot Road Bike??? Help Identify before i buy it? :)
 

found this beauty on craigs list, asking price is 75, the owner dosent know anyting about it other than the frame height from the ground is 30" (my inseam is 31", would it be the right size?) and that it is a single speed,

I have a very similar looking bike. Mine is a "Bordeaux" with HLE tubing that I purchased new in '88 or so. It's a twelve speed. HLE tubing is nothing special. The components on my bike were decent for the era but not high end.

Mine is in very good condition and I expect (or hope) that I could get more than $75 for it, but then again, I'm biased ;-)

I don't know what a single-speed conversion would do to the value although many riders in my area would prefer it that way. I suppose it depends on the components.
