The legendary combination of durability

Chris King Centerlock Lockring - Matte Jet Black Running 5%)Measuring unit integrated into theSold as a single lockring. 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. Comes in 11 anodized colors Made in the USA
