Paint crack or more? I am looking to buy a used bike: a Cannondale Super Six Evo. The seller has sent me a picture about which I am not sure what is wrong. It seems like a paint crack, but can experts share their opinion? It will help me buy this bike. Thanks in advance!

There are 2 marks that I see:


The black mark - as someone noted in the comments - looks like it is due to the brake cable rubbing on the frame. Fairly typical.
The "cracks" on the white paint are a type of paint failure I have seen before, though it might not have been on a bike frame. It probably is nothing to worry about.


When/if you meet them, ask them whether the bike was in a crash. It probably wasn't. Take comfort in the fact that they posted this picture; only an honest seller would note such imperfections in an ad.
