So I've been riding my conversion for 4 or 5 months now, and I noticed recently that the headtube/downtube lug is seperated from the downtube on one side. I also notice creaking sounds coming from the front end of the bike when I'm in the drops or on the hoods. I bought this frame used and I don't know its history, though it was pretty apparent that it had had the **** beat out of it. I crashed it maybe 3 or 4 times, though not very severely. Is the separation becuse of sloppy brazing or from crashes and abuse? Will this frame catastrophically blow up under me while I'm cranking up a hill or skidding in traffic? I am somewhat sentimentally attached to this frame because it is pretty and my first conversion and all, but I will can it and replace if the frame is unsafe.
pics- they suck because my camera sucks.
you can fit a piece of paper this far under it.
