Summing up, some people do slide forward on their saddles to get more power in shorter efforts, especially in road races. If this is the extent of the question, then yes, road saddles vary in length. As already stated, the Fizik Arione is one potential recommendation for people in aggressive riding positions. I think I've heard this saddle is designed for people who vary their position a lot, e.g. sliding forward, sliding back, etc. I've heard a couple bike store managers say that the Arione is mainly popular among racers, however. My position used to be more aggressive, but since I've moved to a slightly more upright position, I found that the Arione isn't playing well with me. I changed to an Antares.

If you feel you need to frequently slide forward on the saddle, then it's possible your position is too far back. If you're new to riding, you should consider this. When I was new to riding, I found myself doing this a lot, and it turned out that I did need my saddle positioned further forward.
