My 1950 Raleigh Superbe will be 70 years old in January. For about 35+ years of that, it was alone in the dark covered in crap. It saw its first ride in glory and shine last summer, and I've been after it for rides ever since. The frame is fine. I'll keep an eye on it for the next few decades and see what happens. I anticipate buying more spare SA hubs for parts. Likely spare alloy wheels in the right size eventually too, and a magnet upgrade for the dynohub. As for the Peugeot and Voyageur, they're still rather new by comparison to some of the bikes posted upthread from the early 20th century. I expect the Voyageur to be around in 20 or 30 years as my touring partner. I'll likely have swapped my new wheelset from the Peugeot to another capable commuter before that given our winters and all. Steel is real.
