Geometry comparator that takes saddle & seatpost into account?
I've been thinking a lot about the differences between a few of my bikes, and I happened across this link tonight: GearInches.com » Bike Geometry Comparator
So far, I'm finding it quite interesting, and there's a lot you can do with it, but I'm frustrated that it doesn't give me any way to include my saddle position into the comparison. Does anyone know of a similar calculator, or perhaps a modified version of this one, that takes that into account? I know about BikeCAD, but that doesn't give the easy and immediate comparison I'm looking for without paying for the Pro version.

My friend and I figured out something of a workaround. What's pictured is two of my bikes, which have very similar geometry. The geometry charts from the manufacturers don't have all of the same information, so a couple things were guessed at. The program used to make these diagrams doesn't allow for saddle placement on the diagram, so the seat tube angles are modified to account for seatpost setback. The diagram shown assumes identical saddles, which isn't the case in the real world at this time, but it's possible to work out the saddle placement based on the clamp position. The handlebar position shown for the "green" bike is based on changes that could be made to more closely match the real-life position on the "red" one.
