RX100 seems to turn up as 8-speed, not 7-speed. These early STI levers are rather heavy btw.
There was a 7-speed RSX gruppo back in those days around 1996.
Again, the old shifters are weighty parts, and somewhat prized for upgrading old freewheel bikes.
Freewheel threadings are all the same as far as your setup and any newer freewheels are concerned. All English threading.
You measure the "axle width" at the points where the axle locknut's grip surfaces contact the frame, should be the same as the inside measure of the frame of course.
Quando hubs have decent bearings in them I've found.
What is this "post width" you mention?
