28T front?
Why make it hard?
Why not get a crankset that offers 22 or 24T?
Yeah I agree on your 11-36
21-112 GI would be way too high a gearing for me and only worsen my knees from over gearing in my misspent youth.
These days I roll with closer to 17-90 although my bike is likely heavier than yours.
Be nice to your knees is my advice and spin.
