Frame reach and stack are only part of fitting the bike to you. What they tell you is if they are nearly the same as a bike that fits you then the headset spacers, stem angle, and stem length of your present ride will likely give you the same fit on the new one. It they are substantially different, then these will need to be figured out for the new frame. Based on the information you gave I would guess the stem would need to be 10-15mm shorter on the Ritchey than TCX SLR 2 to achieve the same handlebar reach. Leonard Zinn covers some of this in one of his columns on stack and reach.

Do you know the standover height on the TCX SLR 2? A Logic 2.0 has a 727mm SO for the 49, 745mm for the 51. With an inseam of 28" (711mm) the 49 might even be a little big.
