overtightened quill stem - steerer damage
I am usually pretty cautious about riding damaged parts for fear of catastrophic failures. However, I have recently purchased a used early 80's sarroni, and while giving it a bit of a pre-ride check over (after I had got it home) I realised that the previous owner had overtightened the stem (on a number of occasions by the looks of it), with the result being a number of concentric bulges in the steerer tube. Is this type of damage safe to ride on? Logically I doubt that this is likely to weeken the steerer that much, but it goes against the grain a bit to ride on a damaged fork. I guess I could always try and find a replacement, but part of the attraction of the frame was that it had the original fork.
Any advice would be gratefully recieved.
