I need a set of stainless 12g spokes, who sells them? I need 48 for a 4x pattern 20" alex supra e rim with nimbus 48 hole hub.
The BMX retailer Danscomp.com sells them. Are you sure that the hub and rim you are using will fit 12g spokes/nipples?
Also 12g spokes will be stiffer, which means it is even more important that you maintain even spoke tension to prevent overloading individual spokes/nipples/hub holes.
