Do you have retainer rings on your Rohloff hub?
There you are. In Mozambique. With your 13-year-old fully loaded Santos tandem. And a broken rear wheel... This was not the adventure you had in mind. A broken spoke or flat tire perhaps? It turns out to be worse: the flange of the Rohloff hub is broken at one of the spokes. The combined weight of riders, tandem, and baggage is almost 200 kg. Continuing to ride with 31 spokes is not an option.
