i guess i don't get the idea of bicycle components as"wall art" just for the sake of preservation unless the item is simply unusable, impractically fragile/unreliable or unmaintainable.

For one, who , besides yourself, would get the chance to appreciate it if it's salted away in your home?

secondly, what sort of destructive abuse would something like a hub see if built up and ridden? Seems to me that if it's well maintained and taken care of, short of some severe accident, a good quality hubset will last for decades without any appreciable harm or wear.

When they are finally worn to the point of considering retirement, and it's time for trading in the bike for a wheelchair, you always can donate them to a cycling museum where, secured under glass in a display case, a worn race won't make any difference anyway.

Of course, that's assuming they don't have 5 sets of them already.
