pragmatic on a tour , in the busy Summer season when you damage the wheels you have (it Happens)
are you willing to stay in some place for almost a week, while a small town Bike shop orders a replacement Rim?
and re-laces it into a new rebuild on your Hub?
if not consider adequate mid line Shimano hubs in say 36 spoke..
then maybe something off the shelf will be in the shop and you can be back on the road in the same day.
LBS on a popular touring Route, here has cut out hubs and boxed them up for mailing home and the rider left
riding on more common spare wheels..
Other than that Best? Rohloff and Schmidt Dyno hub.. Both can be running Discs..
