The King lockring is aluminum with a steel crush washer and has a classic King lasermark to match our headsets and rims.
We spent a lot of time on the exact shape of this piece. In addition to the subtle shaping of the front, the knurling on the back has a very specific shape, so it threads on easily, but it resists coming loose. It also color matches your other King components.
