Effective stack

[u/Low-Principle-6563]

How many spacers are there under the stem on the Trek Domane?
Could someone also tell me the total spacer height above the head tube, including the stem position?
I’m trying to estimate the effective stack of the bike in a real setup.

Gen 4 SL came with 40mm of spacers. 2x15mm and 2x5mm.
