Forgive me if you've seen my similar question on the road cycling. I'm interested in hearing the "mountain" opnion as well. Here goes: I'm a roadie wanting to get into a little off road stuff. 'm torn between your basic mountain bike and the cyclocross, aka Jake the Snake, type of bike. Is there a situation where one works better than the other? I'm thinking the cyclocross set up is more of a road positioning and that might not be good on the dirt. I also wonder if it looks odd to see a "road bike" coming at you on the trail. I want to be comfortable and I don't want to look like a dork. Any suggestions???
