Where do each excel?
Dude, If you are going to do X, you should have bought a cyclocross bike?
Dude, If you are going to do Y, you should have bought a hard tail MT bike?
I don't really want to make this thread about me, but here is what gets me thinking about this subject.
I have a road bike. I am thinking about getting a second bike for riding the potholes, gravel paths, across yards.... I am trying to decide which would be better for me. I am not expecting to race. I am not thinking about jumping off high structures. This is all about getting from here to there and enjoying the ride. Based on what I am currently reading, I think I could do either. Sway me one way or another.
