I am currently riding a converted Schwinn sprint fixed gear and im looking to possibly upgrade my frame at some point.I have upgraded most of my components way above the frame as i have dura-ace crank , lock ring and phill woods cog with a brooks and a nitto pearl steam.I am basically looking for a frame that is size 54, at or under 300 (closer to 250 is better) has a 1" threaded headset , and i can mount a front brake on it or get a fork with a mount for it.I have done some searching around but havent found anything on the forums ( i would like a specialized steel langster but i cant find a frame in my budget)

Thanks
