This question is for people who have experimented with different handlebars on different types of bikes. I have heard that it is not fun to have relaxed, pulled back style handlebars (north road bars) on a road bike with steeper angles. Why might this be? What other combinations might make some sense or no sense?
Mountain bike frame with drop bars?
Old (relaxed geometry) 3 speed frame with drop bars?
any road bike with moustache bars?
How would you determine what might be a good idea, and what might not?
