Yeah, they changed the geometry of the front and rear derailleurs. In front, the arm is longer and there's a little doodad that flips around to accommodate different approach angles from the BB. Out back, the new cage is about mid-size (maybe a half inch shorter than the long cage Ultegra on my Century) but easily works with that 32 tooth cog even without the B screw very far into the base.
