like i said, my latest frame had no metal insert in the headtube, so maybe they have fashioned a way to eliminate them in the BB too. if they can, so much to better. the pic looks like it sure enough is designed that way. so i would just buy the appropriate BB386evo BB and see how it goes.

BTW, is anything tapered in there? it looks in the pic just like my headtube, machined with an angled seat for the bearing.
