I'm looking into purchasing a used bike to get into touring/bikepacking. There is a particularly low price Soma Double Cross Disc bike I've found on Craigslist that I think would be perfect... with one caveat. As you can see in the image below, a clamp on derailleur was over-tightened on the seat tube. My question is this: should I be worried about this too much? Would this be an easy fix for a frame builder?
Obviously, I have to go take a look at the frame and ensure that there is no cracking. This would perhaps entail removing the paint. I'm also going to consult a couple of shops in my area to get some professional opinions. In my mind, this shouldn't be a big deal on a CrMo frame. It's obviously going to reduce the life of the frame, but for a mere $500 I think I'm okay with that.
