It's built! I had to order a few parts and scavenge a few others from my other bikes. I was able to find a Campagnolo Super Record carbon BB, c record brakes, cranks and chorus head set derailleurs. It also has Cinelli bars and stem, Campagnolo proton/electron wheelset and the only remaining outlier is the Shimano 600 tricolor brakes. I can't decide whether I want to add some ergo shifters but will probably do so if some inexpensive ones appear. It feels obscenely light at the moment so I'll have to weigh it soon. Technically it's a few Centimeters too big for me but I'll get use to it!
