Yeah, I've been following the G-Boxx crap. I'm just not sure of where it's going, or whether it's designed to go anywhere except provide some legitimacy to Nicolai. I think Magura or Hayes or someone also bought some rights to a gearbox design, this time utilising a derailleur system housed in a housing around the cranks. Much less weight penalty than the G-Boxx/Rohloff.

Lord knows where any of this is going other than as something for Dave Weigle and Karl Nicolai to do on the weekend.
