I was referring to both.

The Sturmey fives are also available in a narrow fitting, and there's talk
of a narrow 8-speed in the pipeline. But the context isn't whether or not a
112mm oln is universal, but whether or not it's unusual. In hub gear (and
more general) terms, it isn't.

Of course not, and neither will they fit most traditional bikes without a
similar operation.

Again, the context isn't whether or not it's possible to fit all hub gears
to all Bromptons. It's not difficult to find combinations that won't work.

The fours as well, as I wrote previously. And of course many single speed
coaster hubs will fit.
I went to Hadland not because his data is historical, but because its
authoritative, and shows clearly that there's nothing unusally narrow about
the Sturmey hub as fitted to the Brompton.
