Don't forget the equivalent stack height (steerer tube clamp), which can vary from model to model. That affects whether/which spacers you can keep and the pre-load on your star nut from the cap bolt.

I've always thought of reach as being the distance along the stem between the center of the two clamps (center of bar to center of steerer tube). The rise angle is the +/- from normal to the steerer tube. Have I been wrong all of these years?

Of course, that's with modern threadless forks. I'm guessing that most folks are using those now...
