I am particularly fond of retro bikes with new modern drive trains. Up until a couple of years ago my main tourer was a 1969 Paramount spread to 130 with campy 8 speed triple and ergo shifting - with a drop bolt to convert to 700 c wheels. And my new bike is a 1989 Koga Miyata Mountain bike converted to road. Retro bikes make great tourers but I am in favor of more modern running gear - most of my bike are now 8 speeds.
