Pinholes in the chain stay?
 
I was looking at a bike on Craigslist, pretty nice Rodriguez touring bike with a Campy Mirage groupo. The guy selling it says there are two pinholes in the left chain stay and he does not know what caused it or if it is an issue for integrity of the bike. What do you all think? Is this an issue and should it be repaired? Probably a good deal either way, but I don't want to hassle with a repair if necessary.

Thanks - Chris

Maybe vent holes?

Is it a carbon fiber frame? Maybe drain holes.

It is not carbon fiber, it is a custom steel frame.

I was thinking that potentially too, but as the article you reference points out, there is no need to vent chain stays. Unless Rodriguez does it differently. And you would think they would be in the other chain stay as well.

I'd guess the holes are there to help allow water to drain out.

Depends on where the holes are... could be vent holes or rust through. If they are vent holes no problem, rust though or bad weld/brazing problem. Pictures would help.

I think without offering pictures, even asking the question is an act of folly..

Well I still need to see it for myself. But since he felt he needed to disclose it, I think it may be an issue. After talking with him it sounds like they were not there before, but are now which may mean rust. I think I may just pass on this one anyway because I don't want any issue. Thanks for the responses though. Chris
