Shimano specify the FD cage being 1-3mm above the big ring normally, not sure if that's what you're asking?
Or maybe if there's something in the way of where FD would go and it comes equipped with GRX it's 1x specific?
yokes-
Yes i read the docs. Saying the cage was supposed to be this and that above the big ring. Then calculated the diameter of the intended 46t big ring. Then lookaed at images of the FD clamp to try and guess its vertical distance from the cage.
I then decided that, well, it will probably work. Ill get one of those problem solver bolt on adapters with an adjustable slot. And if it doesnt work ill Just go 1x. :-)

The frame i’m about to buy has a braze on for bottles in the area where the fd-band would sit. Is there any way of finding the height a fd would sit in relation to the bb?
The braze on was at approx 115mm c-c from the bb.
The mech/crankset intended are grx600.
