The front rotor is also to be installed the gears adjusted and the derailleurs positioned, I can make sense of all of that with the help of Calvin Jones, but this thin ring I don't know.
The ring if very thin and bendable, the measurements would suggest it's going on the steering tube, but that already came assembled with spacers and the stem…
Any help is very appreciated!
