Confused about GIOS body sizing.

I would be extra involved with the highest tube size. Whereas the highest tube AND the seat tube lengths are necessary, there’s some variability.
Becoming the highest tube and stem size is harder than seat tube size as a result of adjustment vary of a seatpost.

In your case, if the presumably too small Gios doesn’t permit you to increase the bars excessive sufficient then sure; the body is simply too small.

I am not an advocate of the slammed stem place as I really feel it restricts the benefit of trying down the street.

I’ve at all times sized my frames at 2/3 of inseam, then raised the stem to the best attainable place. It was nonetheless environment friendly, energy producing, and comfy.
