I know people who had problems with the 2 speed system.
I don't know people who had problems with the S.A. 3 speed system.
I have the latter, bike is from 1992 and I suspect the rear wheel to be nearly as old as that. Got it second hand in 2007, never had to worry about it.
It's heavier though, I'd go for a 2 speed if I was going for a new Brompton.
