    Dahon Speed Pro - Dented top tube. Cosmetic or Saftey issue?

    Hello Everyone,

    Last week I purchased a used 2003 Dahon Speed Pro from a reputable shop in town. On the test ride, I noticed a large indentation on the side of the top tube close to the steerer and pointed it out to the sales rep. His response was that it "was supposed to be there" - ie. to accommodate folding. I believed him and went ahead and bought the bike. Now I have come to find out that no, it is not supposed to have a large dent in the top tube, and that it is actually impact damage. So my question is - is it a safety issue or simply a cosmetic issue? The frame is 4130 steel, and in all other aspects rides, shifts and folds just fine.

    Its a good bash, though the paint does not look like it has split and it does not appear structurally unsafe. That said I guess it depends on how it was done and if any other parts were stressed like the folding mechanism when it happened.

    Clearly a case of mis-selling though and depending how much you paid (i.e. did you get a great deal) and if its causing you worry I think you have grounds to take it back and ask for a refund.

    Does your handlepost fold to the inside? Some of the early Dahons did have a small indent to make room for the handlepost.. that indent looks bigger than I remember.. my 2006 Speed Pro handlepost folds to the outside.. This Image of an early SpeedPro shows the inside handlepost fold.. I could see where the indent might be warranted.

    The handlepost hinge looks like it does fold to the inside, so likely was to facilitate folding. As mentioned, there are no paint cracks as would happen if there was an accident.

    Ah, okay that makes sense. I had the handlebars swapped for some with a good amount of backwords sweep, so I fold with the handlepost on the outside to accommodate them and still have a nice tight package. It was a good deal and it rides like a dream so I'd prefer to keep it as long as it's safe.

    Even if the dent wasn't supposed to be there, being steel I would still ride it since the dent isn't close to the welds.
    I'm sure the dent is supposed to be there.
    Post a pic with the bike folded as tight as possible and let's see how much clearance the dent provides.

    Ah as some say maybe the indent is suppose to be there. I did wonder why the paint seemed to be undamaged which may explain it ?

    A pic of it folded tight may reveal more.

    Hi,

    I'd say its supposed to be there. It in the right place
    and the right angle to be there to clear the bar post.

    rgds, sreten.
