What is the oldest serviceable bicycle component you have?
The delivery man brought home our package. It was tied to the rack of his Raleigh bike.
I asked him how old it was. He replied 60 years. He had got it as a child, and the only thing that ever needed changing was the bottom bracket.
I don't know if he was bluffing, and I don't have a picture to prove it. But it did look like a pretty ancient bike.
