WTB: I'm in need of a steel frame/bike for a fixed gear project. Size would have to be between 50-52. For now, I don't have many qualifications except I want it to be on the ligher side, with a geometry leaning more towards the aggressive side. Also, it would be nice if it did not have braze on cable guides. I realize this is a bit broad of a description, but I am trying to keep my options open. Thanks.
