I have the same Diamond Back "Ascent" with girder style stem (I love the look, but it is rather long - I feel that I stretch to far when riding the bike).
I am interested in why you chose to change yours and how it changes the feel of the bike.
That seatpostI bought the bike a few weeks ago from the local scrap man. It did come with the 130mm girder stem originally. The Zoom stem is 10 degree rise and 10mm shorter. The head tube and steerer are quite short, so it just raises the bars a bit to make it a little less racy and more comfy. The stack height of the Zoom is quite high, so you won't be able to run the canti hanger under the stem. It fits straight onto the compression ring in the aheadset, the upper allen bolt is just level with the cut steerer tube.

Simple job today ...
Made a wooden duck-board for the cellar floor (my workshop).
My feet are getting increasingly cold standing on the damp concrete floor.
Must be careful not to drop small components thru the spaces.
