I'm looking at a used 07 caad 8. Looking back at the catalog I noticed that they had a caad 8 and caad 9 that year. Doesn't anyone know if they are different frames in the sense that the current caad 8 and caad 10 are or was it basically a difference in components? I can't see the geo chart so not sure if everything is the same
