Edge Alloy Hub Lock Ring
Extruded and CNC-machined from 6061-T6 aluminum, Edge lock rings are super lightweight and very good looking. Replace that old steel lock ring you have now, and save some weight while adding style and color to your whip.
Available in anodized red, blue, gold and black and fit Shimano-compatible cassette bodies. Keep in mind, aluminum is softer than steel, so use care when installing an Edge lock ring.
