I recall with fondness my Alan with Campagnolo C Record from the late 1980's. What a glorious machine!
That utterly beautiful, shiny groupset. My Italian bike dream!
Now I compare it to my Pinarello Dogma F which is very much an exercise in function over form in the most part of its design albeit still beautiful to many, myself included. I prefer the lack of lugs, the cleanliness of a modern carbon frame with zero visible cables. The Dura Ace groupset, whilst nice is not as beautiful as my old C Record, however. I do prefer the look of the Zipp 454 wheels.
Overall, I admire my modern Italian bike just as much as my 1980's one to look at. To ride however there is zero contest for me: the 2023 bike is leagues better in every way. Lighter, stiffer, aero, more agile, more comfortable (28mm tubeless at 60PSI vs 23mm tubes at 100PSI), stronger (yes) better braking (disc), greater number of gears with smaller increments between them, faster gear changes etc.
Then there is my 1980's MTB vs my current MTB...literally no contest. MTB's have truly moved on massively.
There are truly lovely bikes from the 1980s but they are absolutely not peak bike, far from it, they are a part of a wonderful evolution that continues to this day.
