Swapped my tiagra cassette for ultegra. When i used to tighten the lockring on the tiagra it would make a loud and metallic ratchet noise. Same on my other bike, unknown cassette.

The ultegra instead makes a soft dunk, dunk dunk noise. Is this okay and norrmal, is it cos of the soft washer that is under the lockring?
