Currently run a customized 12-32 Miche because Shimano stubbornly refuses to give me 14t and 16t. I don’t often run out of rpm at 12t, so an 11t wouldn’t be my first choice, but I could live with it provided the cruising range is adequately covered. Unfortunately, I don’t think one can do 11-17 as a corncob without ridiculous gaps to get to 32t.

I used to run 12-29 when I never encountered anything beyond 10% on the east coast… now one of my favorite rides hits 12-14% for a few hundred meters…
