Shimano Ultegra CS-R8000 Cassette Lockring and Spacer Info
The Shimano Ultegra CS-R8000 Cassette Lockring and Spacer is the correct OEM replacement hardware for securing your CS-R8000 cassette to a standard Shimano freehub body. If you've lost the original lockring during a cassette swap or need a spare for a dedicated race wheel, this is the exact part Shimano specifies for the job.
Designed to work with 11-speed Ultegra groupsets, the lockring and spacer ensure proper cassette seating and consistent clamping force — the kind of detail that matters when you're mid-ride and need your drivetrain to behave. Keep one in the workshop drawer. You'll use it eventually.
