|I'm guessing center of the steerer tube hole to the center of the handlebar hole is proper measurement.... Is that correct? Thanks for clarification....|

|There are actually two different measurements that are more or less commonly used.
The measurement that you described is called "extension" and is the one used by most vendors.
A measurement taken at right angles from the centerline of the steerer tube hole to the centerline of the handlebar hole is called "reach." On a 90 degree stem, they'll be the same. On a 130 degree stem, there will be a significant difference. Reach is a useful dimension to know if you are buying a threadless stem that has a lot of rise.

|Don't forget, it is the shortest distance from one to the other, NOT the distance along the stem (unless your stem is 90 degrees, that is).|| |
