They are both great bikes. The major difference between the two is that the Pilot is a more upright bike than the 2200. Go to the Trek website and find the archives and look up both bikes to compare the two. Notice that the top tube on the Pilot is at an upward angle so you are in a more upright position, while the top tube on the 2200 is flat placing you in a flatter, more aggressive and more aerodynamic position. It just depends on what kind of riding you plan to do. I would also go to road bike review and do a search on both and see what you can find. A google search on either one may turn up some other reviews as well. Good luck.
