I've owned a Pinarello Montello since '92 (it's an '87), which I converted to 8 speed Chorus, and have kept that way. Both the Montello, and a slightly older Record I recently picked up, will accept a 130mm wheel without even stretching the frame.
I also have a '96 Master Light (with Gilco tubing) that I picked up late last year and rebuilt with 11 speed Chorus (it came with Dura Ace 9). What a gorgeous bike in that over the top Art Decor paint (this is AD4), and it turns heads for sure, and it's a joy to ride. But, I dread the day it gets scuffed up. I wouldnt call the ride twitchy, but the bike just knows where you want it to go and makes it happen - think turn, and it dives in, think straighten out and you're there.
