Not quite vintage yet, but my favorite of all my bikes is my 2001 LeMond Buenos Aires with Reynolds 853 main triangle.



I haven't been able to figure out exactly what it is, but this bike just rides great. Most reviews seem to think the carbon fork is too flexy, but I haven't had a complaint.

More recently I've picked up this 1982 Trek 614, with Reynolds 531 main triangle and Ishiwata Magny 10 stays and forks. I guess that doesn't technically meet the criteria of unnamed everything else, but it's certainly in the family.
