Why We Make It What sets King components apart is our focus on the details. There are plenty of other lockrings on the market, but we wanted our wheels to have a lockring consistent with their quality, look and functionality. Basically, we can't just leave well enough alone if we think we can make something better. Why You Want It 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 - Weight: 9 grams each Note: The Chris King Centerlock Lockring follows Shimano's standard dimensions, featuring a 4 mm thick flange and a 44 mm outer diameter. This design is compatible with all mountain bike forks and frames, as well as many road models. Some road forks and frames, though, require the slimmer, internally-splined lockrings. We recommend checking your bike's clearance before placing an order.
