When I met the gal ten years ago in the photos below, she was in year seven of her around the world tour. She started in South Africa, rode north to and through Europe, then east to Asia, down to Australia, back up to China, then to North America. I met her on the Pacific Coast route, I think it was in one of the Oregon hiker biker sites. I have no clue if she went down to South America, but I suspect she did.
I was very surprised to see a front suspension fork (air suspension) on a mountain bike frame for that type of journey. She had so many location stickers on her frame, the brand and model were quite hidden. She estimated that the frame had 100 thousand km on it. Wheels and pretty much every other part on it had been replaced at least once.
One of her pairs of Ortliebs started the trip with her and had held up all that time.
Her Tubus front rack had been repaired several times. That model was no longer produced, so she kept getting it repaired instead. That rack was designed to reduce unsprung weight.
