Tom Harrop I'll be glad to help you with that. It's a little trig on top of the numbers given in the Geo Charts. The two universal terms are Stack and Reach. The Stack is the elevation gain relative to the BB spindle. the Reach is the horizontal distance relative to the BB.
STACK: 64cm Sam: 67.2cm 68cm Bombadil: 71.4cm REACH: 64cm Sam: 43.7cm 68cm Bombadil: 45.0cm These numbers would need to be tweaked just a little bit to account for the head tube extension above the top of the top tube, but for relative comparisons, they are accurate. If you put the same bar and stem on both bikes and put them at max height, on the 68cm Bombadil, the bars would be about 4cm higher and about 1.3cm farther forward. Contact me offlist if you want the math background. I can give you a spreadsheet if you need it.
