I don't think running a Rohloff is gonna leave you stranded anywhere, though. My opinion, worth whatever you think it's worth.
I took your advice and checked out the Rohloff site. And now that I'm "informed", I feel much more confident about my original statements!
I simply can't see any advantage whatsoever in this hub over the conventional der. system (other than being able to say that you own the most complex, expensive and impossible-to-field-repair hub/shift system ever designed)!
One of the specs I noticed is that they limit the input torque to the hub (to me that indicates a certain amount of "delicacy" of the internal parts). Also, there is no way that a planetary gear system can possibly be as efficient in transmitting power as a chain and cog setup. The laws of physics can't be circumvented by spending lots of money.
Also, there is a mechanical law that states that the more complex a given system is, the more likely it is to fail. There's no way to get around that one either.
Additionally, there's the weight issue - admittedly not extremely important on a dedicated touring bike - but this hub, I assume, is not specifically designed for touring.
I also noticed that there are two different oils, one for winter and another for summer. I assume that the viscosity is the difference. Wouldn't you need to carry the different oils and the change kit for the variable climatic conditions you would encounter?
There IS the singular advantage of being able to change spokes without removing the input sproket. Personally, I carry a cassette tool with me on long trips, although in all these years I've never had to use it.
So, in conclusion, after becoming more knowledgable about this product I am even more convinced that this particular piece of equipment is not in any way suitable for use on a bike that's to be used for an around-the-world trip. Actually, I can't see any tangible advantage for its use on ANY bike if maximum durability, reliability, serviceability, affordability and readily available access to spare parts are to be achieved. Mechanical artwork has its place without a doubt, but believe that it would be especially inappropriate for use in this application.
Peace & Love,
