Yes, but at around a £1000 for a Rohloff hub and with them being sold as almost maintenance free and ideal for world tours and tandems, people expect better.
If you break a normal hub, no matter where you are in the world, you won't be far from a suitable replacement.
A replacement Rohloff hub has to be posted out from Germany.
I don't think it's a common problem, but there are a few stories and pictures on the web.
A Rohloff hub flange is one of the few things I have never broken on a bike.
It can only be a matter of time.
I agree but my point is about the number of failure modes that leave it totally unusable, which as far as I am aware is not many. I suppose it depends on how remote your tour is or what kind of country it is but there might not be too much difference in getting a hub sent out and having to source 'normal' bits. I have read, mostly on the Rohloff site, that they have sent out hubs for free to people while on long distance remote tours. I cannot imagine any other drivetrain part company doing that, try getting Shimano to send you a new Alfine hub to the middle of Africa. No way.
They're not perfect, I've talked about my experiences on other threads but I still think they are the best drivetrain choice for reliability and lack of required maintenance.
