I always wanted a cross bike, I just thought the range of use was cool. I just built up a 2001 Trek xo-1 for commuting and to serve as a road bike. I also plan to race cross in the fall but for now I'm in triathlon season. I use it with slicks for my recovery rides expecially after running 12 miles I don't feel like being stretched out on my tri bike so the more upright position of xo-1 feels nice. I also take a couple of dirt roads on the way home from work. I have to say riding it off road is a great time, I can see my handling skills on the mtb improving from it. Now I just can't wait to learn all the skills I need for cross.
