Here is a excel spreadsheet that I have that will help when comparing fit between bikes. If you have a road bike and want to position yourself to the same fit or you FG/SS or vice versa, this will help..

It will also help you see how frame of different geometries will effect fit and set-up.

enjoy! It helped my and hundreds of other to compare frame and overall set-ups.
