very interesting thread. Now I'm wondering if I'll chop open mt CF frame after it cracks ?
What's interesting is there also a video of Pinarrelo Dogma cut open from the same guy. It's better, not perfect, but better than the BMC but at 4X the price (rough guesstimate). The BMC was pretty bad, granted in only 2 spots, but those 2 spots are enough for me to not want to ride it.
I also think it's important to remember these are ALL made in huge frame houses in Asia. The only way the Company who's painting and slapping their name on it can ever be sure of the quality is to cut open every 10th or 20th frame. Or, have someone at the the factory inspecting the whole process, if that's even possible or allowed.
AFAIK the last CF frame big-name frame made in Europe was the Colnago CF40? Watching that video, you can what you're getting even if it was the older lugged CF design.
