Shhh...I am trying to sucker someone into buying a really cool Cannondale! Or....I am hunting wabbbits.

But joking aside, I am thinking that you are correct, though there seems like there should be a little bit more stability, since the forces would be distributed to more metal....but I guess you are right... the pivot point staying the same.
