During the past couple of months, I've been looking at what gears I really use the most on my 1x9; with the thought that I would build up a winter bike with one most used ratio. Found myself most often in the combinations that are 36 and 63 gear in. So I was going to set up a single speed with 63, then i realized 63/36 is 1.75, almost identical to the range of a 3 speed hub. For winter riding, think I'm going to build up a Surly 1x1 frame with a three speed hub and studded tires.
