Dear sophisticado, if I were you, I'd retain my road bike and tour the way you used to do. Why compromise the joy of biking the Alps? If you want to camp occasionally, include ultra light tent, sleeping bag and pad with your baggage. Why cook, when you can sample the continental cuisine? If you enjoy full loaded touring, then trailer would be my only poor alternative. BTW, I suppress my dire desire for accelerated blasts till I get back home from a long hard tour.
