Brand new vs. 80's steel.
I have been mixing it up, riding a new Pinarello and DeRosa with Record and 80's bikes with Super Record. This is a pretty accurate comparison, as the bikes both represent the best for their time.
Besides the shifting, the 80's rides are smoother (by a mile) more stable, and more comfortable.
New bike has climbing (gearing and lighter), and acceleration.
I am running Speedplays and Campy Pro-fit pedals on all, so that eliminates that comparison.
Gotta love the older stuff!
