One more example came to mind. I met the gal in the photo below 9 years ago, she was on year 7 of a LONG tour. She said her bike had over 100,000 km on it. Most components had been replaced at least twice. But the racks were original. The front rack (Tubus Swing) was no long made, so she kept having it repaired because it could not be replaced with the same model.
That looks like the older Tubus Logo (not the EVO version) on the rear.
I can't think of a better recommendation for a Tubus rear rack than this. She started in South Africa, rode up through Africa into Europe, then east to Asia, south to Austrailia, north again to China, then across the Pacific to where I met her going south on the Pacific Coast route in Oregon.
One of her two pairs of Ortlieb panniers were also original.
