I've gradually worn the outside 7mm or so edges on my drive side titanium bb shell and a brand new bb will now not stay secure. I don't want to go to the hassle of getting the frame rethreaded with an insert but think a longer threaded section of bearing cup would provide sufficient grip to stay tight in the frame. I'll used ptfe tape on the worn threads as well.
My question is do you think it'll work, and with this bb? And any reason I shouldn't go for the 68/73mm version as I always have? Is the 83mm version just with a wider plastic centre section?
