57cm was the recommended top tube, 68cm is the effective length with stem so that would make the Stem a 11cm (110mm) stem (68-57= 11cm).
For reference I'm 5' 11" with 32" inseam, my recommended reach (effective Top Tube) is 67.85cm Center-to-Center It's 67cm on my current ride (just measured). I think I look sort of normal
