Well, since we can't see the picture anymore, who knows? And I am not
sure that *anyone* could tell if a pinhole in a weld is of concern from
a photo. Take it in to the dealer and see what they say- you've got
nothing to lose except some time.I think looking at the photo, you could tell that it wasn't an issue.
It is strictly cosmetic. From the photo, it could be a spec of dirt or
a pinhole. Either way, not a structural concern.Life is Good!

A spot of dirt would rub off and I wouldn't have posted about that. It's
a small hole in the joint.
Looking at that, I see no serious defect. This type of weld
irregularity is common in fact, and would only be a cause for concern
in extreme-stress pressure vessel and aerospace applications, not in a
bike frame. It's probably just the result of a [censored] bubble. The fact
that there's a visual pinhole at the surface does not prove much; the
hole would have to be just the top of a much larger defect before it
would be any cause for concern, and had it been such, the failure you
fear would already have taken place if there was going to be a failure
at all. With five years in service, I'd say that the frame's
reliability has been established. I'd dot some touch-up paint over it
and ride. It's not going to cause a failure IMO.
