I plan on riding in group rides every weekend and I also want to use this on my multi-day rides. What is the main difference between a road bike and a touring bike? I thought they were essentially the same; just stronger frame. I also plan on riding some of the charity rides every now and then. I have been on long trips on my MTB but that stuff is for the birds. I need a road bike so I can keep up with others during my group rides.

I will also be crossing America unassisted.
