This is a feeler, because I'm not sure anyone would be interested in swapping for a non-vintage bike. I have a 2006 Fuji Roubaix RC size is 56cm and it doesn't fit me. It's an aluminum frame with carbon seat stays and carbon fork. I would include the headset and seat post clamp in the trade.
I'm looking for a more modern steel frameset (e.g., tange prestige, reynolds 853, true temper ox) with a 57c ctc top tube and 73degree angles. A tallish headtube would be a bonus.
Let me know if you're interested in the Fuji.
