Schlumph Mountain-drive in bottom bracket

Will the Mountain drive fit in a Dahon bottom bracket?

Option 2
Rohloff Speedhub - 14 in rear

Will the Rohloff Seedhub fit in the rear drop outs with out using a tenioner? How wide are the rear drop outs?

Option 3
Rohloff Speedhub in rear
Mountain drive in bottom bracket

This is not going to happen because of cost and overlaping gears. But fun to think about.

Will any of these Options work and what are the good and bad points?

I'd go with option 1, but with the Speed Drive, which is a 1.65/1 overdrive... the MountainDrive is a 2.5/1 underdrive.. the Schlumpf easily fits the Dahon BB.. I've been running the 8spd Shimano and SpeedDrive since early 2006 without problems.. it's a slick set and has a gear range is over 500% .. there is another member on this board who is running a Rohloff in his Dahon XP.. AFAIK, he was very happy with his setup also..
