I don't know, but looking at the Cinelli I see the frame is 1000g. Another you might be interested in is the same one I have, a DB Podium E'Tape Disc, which they say is sub-900g. If you register for a corporate account the entire bike is $1495, less than the Cinelli frameset, and you could sell the components if you don't want them. They have a M/54 in stock that looks to be your size. I can tell you the ST length in the chart is c-c. My 56 has a ST of 56 c-t. And it's a smooth riding frame on rough roads, smoother than any steel bike I ever had.
