They come with plenty of stack spacers, so you can lower the bar about 30 mm if required.
My SL 7 Disk had something like 35mm of spacers as shipped. After my first ride, I lowered the stem 25mm, and eventually had the leftover steerer cut off. I just checked and Canyon states the possible spacer stack under "Geometry/Component Geometry/Spacer in mm".
