My tours are short, a week at most, and no mountains (yet). I was running a Nuvinci hub with a compact double. After a while I realized I was only using one chainring, so I removed the derailer. Around town I would use the big ring, and if I was hauling a load, I would manually move it to the small ring. Then I got the new version of the hub, and I was having trouble getting the big ring to work with the narrower chainline, I went to one ring. Now I'm running an Alfine 8. I'd like a little more in the upper range for riding around town, but I'm guessing the small ring will do the trick when I'm touring.
