I thought a lot of the nahbs bikes looked a lot smaller, closer to 1:1 gearing.
Gear inches ftw.
559 + 2 * 2.2 * 25.4 = 671mm = 26.4" overall diameter
So 32:16 on 26x2.2" = 52.8"
559 + 2 * 3.8 * 25.4 = 752mm = 29.6" overall diameter
52.8/29.6 = 1.784
34/19 = 1.789
622 + 2 * 3.0 * 25.4 = 774mm = 30.5" overall diameter
52.8/30.5 = 1.731
33/19 = 1.737
Also, 32:16 is classic SSMTB race gear, not "go exploring, ride up the Eiger" gear.
34x16 isn't unreasonable?
