The Box One Alloy Hub Lock Ring is made from 6061-T6 aluminum alloy. It is a great way to save some weight (over a steel ring) and add some color to your bike. Fits Shimano-compatible cassette bodies. Pay attention to how much torque you apply when installing this since aluminum is softer than steel.
