also... use either a machinist' protractor or a cell phone angle app to check the head tube angle with the bike in the "lower tire pressure " stance... see if that spec matches the bike spec. as called out by Cannondale... adjust if needed. Re-measure the ground-headset cup distance... do the math, find your new fork. Don't forget to consider needed Tire Clearance in the vertical direction...
oh, and that sidewalk is not level to the wall's grid...
this may be what I need to do. Would love to have a measurement of an appropriate fork as reassurance though!
I'm aware the ground is unlevel in my image, but it seems odd in all of the other examples that I can find the visible slope is consistent.
And then a 1991 ST1000 as a reference with a visibly shorter fork and perfectly level top tube
