At KB Wheels we use Sapim spokes and nipples. These spokes are top in the industry, fabricated to the highest standards, and arguably the strongest spokes around. They come in various sizes and regardless of your riding style and build, one of them will be a perfect fit for your handbuilt wheels. We also use Sapim’s secure lock aluminum or brass polyax nipples. They are a little more expensive because they have a patented mechanical locking mechanism that allows a wheel to be re-trued easily down the road. I’ve lost count of how many wheels I’ve re-trued where loctite was applied to the nipples and I ended up removing all the nipples, cleaning the spoke threads, and re-building with new nipples, and that is a lot more expensive!
