I generally prefer riding my fg. It fits perfectly and I enjoy the sensation.
The road bikes get used in situations where it is more practical, like long rides with lots of elevation, certain group rides, and the little amount of formal high-intensity intervals I do in the spring/summer (like sub-3 min stuff where you need a big gear). And road races ofc.
I spent 14 hrs training last week and 7 of it was on the fg.
