I know these topics have been discussed before, but if anyone is so inclined, I'd be interested to hear current thinking based on the latest options in terms of bikes and hubs.
I already have a nicely equipped Surly LHT (link to a blog post about my LHT), but I'm interested in a folder that I could readily take on Amtrak for roughly week-long tours with front and rear panniers.
It seems like my best bet is probably Bike Friday's New World Tourist (link to Bike Friday's page on the NWT Select), but I'm intrigued by internally geared options such as the new (availability?) Tern Verge S 11i (link to Thorn USA) or maybe even a custom NWT built around an Alfine 11 hub.
I'm more concerned about extra weight than I am about reduced gear range. Although I've never had to on my LHT, I don't mind the idea of having to get off and push were I to tour in a mountainous area. My attraction to the IGH is to reduce vulnerability when the bike is folded up and placed in luggage compartments and overhead luggage racks and, I suppose, overall sleekness.
