1" steerers were butted , going to 1.125" they got to eliminate the butting, so it got cheaper ,
the tubes, then, could be bought in 40 foot lengths, that fit on the truck, & then were cut in needed lengths..
A Brompton Fork is 1.125" & threaded, folding stem mast is a 1" Quill .. 36mm headset wrenches used.
Quiz; Any one else selling bikes with a 9/8" threaded forks, today?
