I have successfully put a GRX 46-30 chainset onto my otherwise Ultegra Di2 setup.

Interesting, as they say you'd need the GRX front mech for those with the wider chainline.

was hard pressed to find a difference between the mechanical R8000 & GRX front mechs.
Pulled out the vernier (with battery but sans cap of course) and measured.
The cage shape is a tad different, everything else was the same.
My conclusion? R8000 mechanical front mech can handle it all, GRX is braze on only and thus may need clamp = more cash for no reason.

It's right at the limit, just shifts far enough to get into the big ring and not rub, limit screw (or whatever it is) is all the way in.

Well that's lovely. I actually have the 5801, but the shape is very much the same as r8000.
