I am building a pair of wheels and I got a set of neon red spokes and a pack of white spoke nipples. I didn’t have much choice in the colors of the spokes and the nipples as the stocks and choices are severely limited.
I did encounter what I consider a huge problem when I was about to start truing the assembled wheel — the spoke nipples did not fit any the spoke wrenches I have which are shown in the above photo. The white coating of the spoke nipples made them thick enough that they will not fit a standard spoke wrench. I had to disassemble the wheel again and ditch the white things for standard nipples.
The lesson here is to never buy those coated (colored) spoke nipples. Ever. They are next to unusable as spoke nipples but I could probably make a necklace or a wrist band out of what I already have. Or maybe earrings.
