>From the other side of the range... My PBH is 86 but a SH somewhere around 72.5-73cm works best for me. I always measure on the centerline even though I'm one of those long femured people who slides the saddle back, even with 71.5 degree SA's. I have had bike fitting done as well and their recommendation is always higher than my hamstrings can handle.
