cyccommute: How would you rate those bikes if you wanted to commute and tour? I'm thinking one of the things that impresses me about surly is the clearance they allow for various tires.

What are other options? My knees have been such a wreck recently that I am now thinking I should get rid of my fixed, my road, AND my MTB and get one bike that I can use to commute/get around and tour with. Am I repeating myself?
