To use automotive vernacular, my bike is a resto-mod. It is actually a mid-90's LeMond. Everything is original except the saddle and wheel set. This entire process started here:

So, I've got new shifters, crankset, headset (existing one is worn), rear derailleur, and threadless stem with adapter. Soon to be added are new bars and a quill stem instead of the stem/adapter combo.
The bike is 22lbs right now. I was hoping to find 750g (2lbs), but it appears that getting much more than 1lb off will cost a small fortune.
I like a lot of the ideas posted ITT, though.
