I have been around for a while but I confess I am still ignorant of certain things. I have had mountain bikes and hybrids. I was wondering what is the difference between hybrids and road bikes? I know that road bikes have a drop bar and higher gearing but I can't fathom really it being any different from the hybrid. The higher gears of the hybrid are beyond my ability to pedal except down hill so does it matter?

Would all I need to do is to install drop bars on my hybrid to make it into a road bike??
