Seriously though, I feel like there's a certain weight/size tolerance for a lot of overseas components. I tend to include that in my risk assessment when buying stuff from China. That seat stay design might be fine for someone my size, but for someone who weighs more or has different dynamic leverages, it might be problematic.
Makes complete sense. From an engineering & manufacturing standpoint, i still think it doesnt make sense for them to produce such an exotic feature, but from a risk perspective, you could feel ok with the risk, while i never could. if i did and had an issue, my engineering friends would just laugh at me, and i really couldn't blame them.
