well actually got around to test fitting the sachs forks.
so close its scary
all its gonna take is milling out the bearing race a little
and shaving the perimeter of this to apply pressure to said bearing race.
ill probably have to cut some knotches and make a special tool to tighten it but no biggie.
then just a small spacer to cover up the 1-2 mm worth of thread that will be exposed.
the bottom bearing race and sachs steering stem all fit perfect.
