I'm thinking nothing would beat a co-motion americano, disc brakes, probably switch chainrings down to 44-22, friction shifters on a derailleur.
I've ridden west coast, a couple other long rides. Did most of them on an LHT (frame crumpled from an accident) and a rohloff thorn nomad mk2. The thorn is awesome, but 1) the rohloff is adding drag. Might be able to fix this, but more importantly 2) gear range is limited . 11-34 and 44-33-22 would give me pretty much the same low end (17.5"), but a 108" high end, as opposed to the thorn's 90.6".
Any other bikes I should consider?
I should add that I have all the other gear, ortlieb and arkel panniers, as well as a bob. Just need a new bike :-).
