Is my frame toast?
I was planning a major cleanup of my Cannondale today, so I took everything apart. As soon as I removed the cranks, I noticed some gashes in the frame around the BB shell. Its more prominent on one side than the other. Pictures are attached.
Before I pull the plug on this frame, I am going to take it to the LBS, have them remove the BB and inspect the frame quality. But I would like some advice on what you guys think also. I am not quite sure how the frame was damaged on the outside, its like something rubbed against it, since the mark is semi circular.

Hard to tell from the pictures but thye seems to be more scrapes in the paint than real damage.

They do fatigue to a crack over time, so might be..
to be on the safe side, strip the components and go shopping.

This looks like typical marks from chain drop, and I wouldn't worry. You might touch it up with some paint or nail polish, but it doesn't matter either way. The BB shell is an area with plenty of meat, and failure is unlikely, and even if by some fluke it does fail, the consequences won't be any worse than having to walk home.
BTW- most of this kind of damage doesn't happen when riding, but when working on or transporting the bike.

Thank you guys, for a quick feedback. I agree the pictures don't do justice. On top of the scraping you are seeing, the shell is bent slightly in one place. It is somewhat visible in the first picture (7 o' clock). In any case, I am going to the LBS now to have the BB removed and shell inspected. I will keep you all posted. I really hope this frame lives for another day.

I have good news. I had the LBS take the BB out and inspect the shell to see if there was any damage on the inside. It looked fine. So looks like the frame is okay. Thank you all for the feedback. I was getting worried that I eoukd have to drop some serious cash for a frame and fork.
