I'm investigating having this bike built using internal
geared hubs or some combo thereof.
Right now the only two systems I'm semi informed on are
the SRAM dual drive. see link http://sheldonbrown.com/harris/sram.html
The other option is the totally internal Rohloff. see link

So I'm soliciting opinions on both these system as well as other systems
I'm not aware of.
