Sram cassette 12 speed problem
Hello. I need help people. I wanted to wash the cassette (sram 12 speed) I pulled it from the axis. pulling out I didn't remember where the washer was. this washer is so conical. now I don't know if this washer is between the cassette and Hub, or between the cone and the cassette. does anyone have such a solution in their bikes ??? or maybe someone knows how it should be correct. thank you in advance and best regards. I attach photos.
