> @grok, so if even at maximum limit screw the chain still rubs over the front derailleur cage when in SMALL (front) - LARGEST (rear) gear, what is it sign off? Not enough tension in the cable?

Not enough cable tension on the front derailleur (cable too loose) — the derailleur may not be fully pulled inward; add a bit of tension at the pinch bolt or via the barrel adjuster.

hmm
