i was just calculating front centers on exel out of interest, i found out that different manufacturers have very different front center numbers for bikes of similar size. it also goes to show how bad top tube length and even effective top tube is as showing frame size. (and this isn't on bike which have interrupted seat tubes which make eff tt measurements even less useful)
on my short size (17.3") commencal, i have a 17.4 front center, 22.2 eff top tube
a medium (17") sunday , it has a 16.6 front center, 23.5 eff tt
a large (19") sunday, it has a 17.6 front center, 24.5 eff tt
a medium (16") dhr, it has a 17.2 front center, eff top tube not known)
i am only 5'8" and ride what (now) seems like a bike way to big for me, i knew its was long and like it like that, i actually want it a bit longer. so does that mean if i was to get a sunday, i should be getting a large frame? which ih recomends for >6' riders.
edit: more numbers:
17" v10, FC-15.3, TT-21.9
17.5" v10, FC-16.7, TT-23.2
19" v10, FC-18.2, TT-24.8
15" 224, FC 17.1, TT-22.8
17" 224, FC 17.9, TT-23.6
