A surly cross check. I had my lbs build up mine and I love it. I can put on 23c tires or up to 42c. Clearance for fenders if I want and braze ons for a rack. It's the all purpose do everything bike and I love mine. Pictures here.

I have two wheelsets, one for road tires (currently 25c) and one for touring tires (Bontrager 38c). I just put on the new wheelset and I can do everything from smooth roads to rail trails and light off road.
