Don't forget, guys...we're talking "mass-produced" here- which means it has to be done fast & easy....i.e. NOT by precision craftsmen hand-measuring and touching up every bore and clearance and installation carefully and by hand. We're talking automated machines stamping stuff out and pressing things in...which is probably ultimately the reason BB30 was invented. In the instances where it is done with more care and precision, on hand-made, hand-assembled high quality bikes, maybe it can be done with better results [MAYBE...]- but then, using BB30 under such circumstances is pointless, isn't it?
