My thing is this.I just bought a bike on e-bay that was listed as 54 but on closer examination and checking the dimensions in the catalogue is actually a 51!The pic looked less than 54.BTW there is no 54 in the catalogue there is a 51 and 53. but I thought perhaps it was just the bike like some pants run small.I posted about the bike in Vintage.It's a 2002 Lemond Tourmalet.I've decided not to cancel as the price was good and it's exactly what I was looking for if a little smaller than I'd wish.BTW my inseam is 28 which is shorter than most people my height 5'8'.
