By pinion frame do you mean a drive shaft instead of a chain? Andy.
Unterhausen is correct, I'm referring to the bottom bracket based gear system from Germany with more range than a Rohloff. It also centers the weight on the bike rather than making you tail heavy like any internal gear hub with more than 5 gears does.
It also makes taking the rear wheel off both for travel purposes and fixing flats much simpler than with an IGH.
Other than the weight, it seems a perfect match for an S and S coupled configuration to me for a travel bike.
