My downtubed Bianchi was converted to an indexed shifting downtube bike. What a world of difference. When Campy Ergo brifters came out, I upgraded again and it was one of the best upgrades I ever made. I still have a downtube shifting bike which is a dedicated rainy day bike, because it also has a small cassette and I don’t do climbs on rainy days. I still enjoy riding the downtube shifter, but when pushing it, the others just work better. I believe it is called progress.
