Asking here because this seems to be the place for small wheels. On my 700 wheels, I stick to 36 spoke in the rear because I'm a heavy guy (200+), and tend to carry a lot. But I feel like I could go 32 on a 20" hub and still have just as strong of a wheel. I don't have a good enough understanding of the math to know that for sure. I just know that smaller wheels are supposedly stronger, the ones I've made certainly feel much more solid than my 700 wheels. But it still makes me nervous, so I thought I'd see how the experts feel about putting a lot of weight on a 32 spoke, 20 inch wheel, because 32 spoke is what I have to work with.
