I doubt it's a drop in.. at least on Brompton.
Alfine axle width is much wider than the rear dropouts on Brompton s, for example.
So a frame spread To suit. has to be done and, not as easy as it is on big wheel steel frames
On my AW3 hub, I found just fitting any larger Cog than a 15t hit the ends
of the rear section's tubes ,
so the cog diameter has to be small .
Bike Friday OTOH, sells a whole bike with the Alfine hub as an option.
