You can get steel frame weighting only 1,000g nowadays.
Pics, or it didn't happen.
1kg steel frames were mooted at the launch of 953, but actual medium sized frames built stiff enough for normal people are coming out nearer to 1.3-1.4kg. Maybe if you selected only the thinnest available 953 tubes and made a 48cm sloping frame with profiles selected to keep the butts as short as possible you could get down to 1000g, but that's a weight that carbon can hit in a frame properly specced for a big heavy rider like Thor Hushovd to race at Paris-Roubaix.
