^^ A variety of reasons really. A desire to something a bit different, doubts about the ergonomics of the Brompton's twin-shifter half-step gearing, a preference for the single thumb shifter on the 5 speed hub. And originally I was going for an 8 speed hub until I decided it was just too fat.
I now look back fondly at the 6 speed system though. The Ti Brompton may well end up being a 9 speed 3x3 Brompton at some point, as I'm still not that enamored with the 5 speed hub.
