375 it said actually, but you will notice the difference on identical bikes with tubesets that have that dramatic of difference, the closer the level of the tubeset though the less noticeable it becomes of course.. like riding 531 and SL I doubt anyone notices any difference between those two, with the exception of possibly frame builders and pro's.
