What's the big fuss about Campag?

it's just a bit of tubing slightly thinner in the middle than the ends that was once used to make bikes.
it was superceded a long time ago.
it's a bit of old tube not a whole lot awesomeness.

So that's it, it suffers from "RetroVintageness" syndrome.
It's not necessarily useful/up-to-date anymore, it just sells a lot.
