For 700 X 25 / 25-622 tire with 175 mm cranks With 11-12-13-14-15-17-19-21-23-25-28 11-speed Cassette

Once you notice about a .3 change in gain ration, it's fun to play around with it to match up crank, chain rings and cassette(s) to get the gearing you want.
It might be hard for those manly men on 52 or 53 chain rings to admit that your 170 crank with a compact 50 /34 or 36 is much closer to their gain ratios than they might think.
