I like the older steel frames with their pretty colours and chrome ( and a horizontal top tube). But I am also a rider, all my bikes should be in such a condition that I can participate in a clubride and be able to mix it up with the guys riding the latest dull carbon black electronic racers.
My handlebars and seatpost are period correct, but derailleurs and brifters are not older than Ergopower 8 speed, and some have 2x10 speed.
Ride those bikes, hard, as that is what they are designed to do.
