lockring
Threaded fastening ring
A lockring is a threaded ring that secures components in place, preventing them from loosening under vibration or rotation.
In cycling, lockrings hold cassettes onto wheel hubs or secure fixed-gear cogs to track wheels.
Similar rings appear in plumbing, machinery, and camera lenses.
Tighten the lockring with a spanner tool.
