IMHO The first Frame (carbon) manufacturing company that proactively offers a written BB spec guarantee wins.
It is obvious that existing lifetime warrantees, really aren’t.
Its our worst fear, you spend $x,xxx on a bike and the OEM BB fails prematurely. Only to find out that the shell is the issue and any replacement you make will suffer the same fate.
Yet worse, even if you are aware, it’s a problem you can’t detect at time of sale unless you buy a bare frame.
Titanium is not my frame material of choice, but I’m feeling pushed in that direction.
