I have what I thought was a Sturmey alloy 5 speed. It turns out on cleaning
that it says 3 speed. There are numbers "56 10" (I presume means Nov.
1956). My questions are:
1) Are the internal gear ratios the same on the alloy as the steel hubs?
2) Does anyone know a source for those 3 or 4 speed clusters that fit where
the single cog goes?
3) Is there a cogset that is any better (ratio-wise) than any other?
4) Anyone service these things? In an ill fated attempt to remove the axle,
some little thing went flying and I never found it. No idea what it was, but
I figure it was probably necessary.
5) Would I be better off with a 4 or 5 speed alloy hub? I'm thinking about
the ratio spacing.
