What year are you looking for? LeMond went from a classic/straight top tube design to a sloping top tube around 2004 or 2005(ish). I've never seen a reference to a 47cm size in the newer models--just 45, then 49. Standover height for the 49 seems to run 728-732mm depending on model, btw.

If you're talking about one the classic steel models, the standover of a 47cm frame is 739mm. (http://ia700102.us.archive.org/13/it...2001Lemond.pdf)
BTW, based on your last LeMond thread, I just thought I would mention that we're the same height, I have about half an inch greater inseam, and I most comfortably ride 51 or 53 cm LeMond bikes.
