Wheelbuilding
I pulled the (ailing) S3X hub from the 3-speed project bike and replaced it with a regular freewheeling 3-speed hub. I lose the what-you-see-is-all-you-gettedness of a fixed gear, even one that’s actually 3 (or two+a freewheel) fixed gears, but not having so much of the element of surprise (of “when will the next gear fail and will it maim me when it does so?”) when riding is a good thing.
