Also Weinmann makes a wheel with 12 gauge spokes. I found my rim at the local bike shop.
I went through 3 wheels in two months the fourth was the Weinmann and it is the strongest wheel
I have ever had. One more thing that might is i think they call the spokes s/s spokes for super size spokes. I have surched all over the net to find it but this is as close as I can come to it. It is only a 20in
I would call some bike shops they can order it for you but call and do some pricing first. My wheel cost around $60
