I never checked or noticed until now, but the bottom of the top tube is very slightly bulged at the bottom. It's easy to miss if you're not looking for it, but I can feel and see a very slight bulge at bottom of top tube. It was not disclosed at the time of sale, and I no longer have the sellers contact info (purchased across state lines). However, I kind of blame myself for not noticing it before buying the bike. The bike rides awesome, and I wasn't aware of how serious this damage actually is. I take it out for short hill climbs close to the house and don't travel far with it. It's also good to know that I should be continuously checking it for cracking in that area. It is a shame though, cause I love the bike so much. I guess it's a lesson learned for me to check bikes more thoroughly before buying them. Thank you everyone for helping me with this, and be safe.
