I've developed an interest in building up some form of this beast (referenced as a "Supermotard". Built by Amaro). I would like to tone it down a bit...I would essentially like track geometry for sharp handling but a fat tire for making quick work of the crater-laden surfaces called roads in New Orleans. Some roads are fine, which leads me away from a mtb style bike.
What SS/FG/Track frames would allow for a fixed gear, 26" wheel with fat (>2.0") slick tires?
