Steel Serotta (1990's?)

[SarahVPritch]

Hey All! A friend recommended I pop in here and see if I could pick the collective hive brain on my Steel Frame Serotta. It was custom for my dad (I think in the early 90's, possibly earlier). I can't quite call it vintage, because I still love my dad and I don't think he would appreciate it.

I found the bike in the back of our garage collecting dust. Everything is a little gunky because it hasn't been ridden or maintained in YEARS, but structurally it is sound. I do not know much about Serotta, but the stickers tell me:

TANGE Prestige Serotta LT Colorado
Campagnola Components

The sizing is unknown (at this moment) but my dad is 6'3" and used it competitively. I will dust it off for the serial number and get more detail.

What I am looking for is recommendations on what to do with this little gem? Clean it up and sell it? Sell it as is? Clean it up and ride it?
