I was thinking the same thing while looking through your pics. I'm about as fanatical about Dura Ace 7800 as everyone else was about Lance about 5 years ago, so I would have been torn about changing anything on such a cherry example. Fortunately, all mine were offered solely as frames, even needing spa days at Cyclart.
If you do change anything, don't let the C&V guys find out. Haha.
That wasn't a pic I posted, but I never get tired of looking at Pelotons, even the red 84 & 85 models look great to me.
