Dave, the top of the seat tube on a Riv corresponds to the top of the top-tube, because their frames are lugged, and as such there is no extension of seat-tube above the top-tube. The Surly LHT and CC models are sized exactly the same way that Riv does their sizes, even though they * do* have that extension (an artifact of their tig-welded joinery). They do not include the extension of ST beyond the TT, but measure from the center of the BB to the top of the TT, just as Riv does.
