I honestly don't feel the need of a higher stem @ 5'9". What I would love to have is:
1-a Brompton size once folded;
2-a Brompton Wheelbase;
3-V-Brakes (or any other effective system);
4-higher gear than Brompton (not necessarily more gears, 3 would work, 6 would be better, Rohloff 14 if unlimited budget was provided)
5-light components (XT brake levers, XT cranksets, XTR if unlimited budget was provided).
6-a custom hard-case that would fit the bike PERFECTLY inside with no room for destruction.
I would be a happy man.
