There are lots of different variations. A lot of people break it down into just road and mountain biking. But, there are more than that; there is causal riding also. The bike companies have done a tremendous job at making new bikes to fit new segments in the public. So when you say, road biking or road cycling, that can be anything from somebody going from 5 or 10 miles just casually around the neighborhood to somebody who goes out and rides all the way across to the State of Texas at either 100 or 150 miles a day. So, it is a pretty broad definition. Mountain biking is obviously getting out on a trail and usually they are riding on a fixed loop for a couple of hours. There is recreational and professional biking. There is varying levels of both types of those and that's the way it is usually split up.
