Excellent reply, Calnago. :thumbup:

That clears everything up, and makes complete sense. The revised chart is so much more understandable.
Thanks much for help to me, and to the Forum in general.

Happy New Year!

as an addition to what calnago said: compare traditional and sloping geometrys, best 59 and 56s, because those have identical steering angles and seat angles:

59: 169 scs + 395 reach = 564; 0=577
56s:156 scs + 396 reach = 552; 0=580

you see the difference at 59trad. is much lesser than at 56s.

why is there a difference at traditional geometry at all? (seat angle and steerer angle are nearly identical!) its, because the measuring point of "reach" is higher than measuring point of "0" at the steerer tube, calnago already declared it!

the chart is a bit misleading, because it creates the impression of reach and scs being complementary. but those arent!

btw: didnt read the whole thread, but i vote for the parlee!:-)
