I started with a hybrid, moved to another country, bought another hybrid, got into endurance cycling and decided I wanted something more suited to it. I was drawn to road bikes because of the lower aerodynamic resistance and the additional hand positions.
I bought a cheap roadbike to try out dropbars and see if I really liked them. I decided that roadbikes work really well for me, but then I trashed my bike in a bike-vs-car accident, so I'm back to the hybrid until I can settle on (and afford) a new road bike.
