I've seen your Superior posted on the site and it looks incredible, that orange really pops! There's no question as to why it would be your favorite bike.
I read a few posts stating that these were built with a number of left-over parts, so that would make sense with the SR seat post. I have a Campy seat post that fits perfectly and a Cinelli stem and set of bars that will be taking the place of the originals. The original stem is a tad shorter than I prefer, so I figure a little upgrade is due.
I plan on swapping the brakes as well, but I'm not sure which to use at this time.
