I honestly don’t see that top tube crumpling under any normal use. In any event, it’s not like it’s not right in front of you if, by some remote chance, it started to go. The top tube is under compression, so if it goes as a result of this dent, it’ll bend and crumple, and I don’t see this happening catastrophically, but rather a slow bending over time. Would this bike be my pride and joy? No. Would I ride it? Absolutely
