I want to try cyclocross. I have road bike and XC mtn bike experience, but I've never cyclocrossed before. Can I adapt my road bike so I can try cyclsocross on it, or do I need a different bike for it? My road is a '04 trek 1500. I'm interested in selling it for a cyclocross bike or a single speed commuter type setup, but don't want to dump the money into a cyclocross bike until I'm sure that I'll enjoy it and it'll be worth the money. Any suggestions?
