Extruded and CNC-machined from 6061-T6 aluminum, Edge Lock Rings are lightweight and cleancut. Replace that old steel lock ring you have and save some weight while adding style and color to your whip.
Available in Anodized Red, Blue, Gold and Black to fit Shimano-compatible cassette bodies. Keep in mind, aluminum is softer than steel, so use care when installing an Edge lock ring.
Weight - 7 grams/0.24 ounces.
