Miche Primato 10 SH cassette 10-speed

It took awhile to get it working for my 10 speed system but you have to follow the instructions. You need some searching and on Miche's website they show that you need the black spacer ring and the silver spacer ring that came with the cassette. They are not packing spacers! They are to work with the cassette. The black spacer ring is positioned before the largest cog and the silver spacer after. Follow the lockring torque settings. Follow the torque settings on the lockring. The red spacers are plastic and they need to be compressed by the torque. Worked flawlessly. Mine is a 14-27T.
