Miche 11 speed cassette for shimano freehub bodies. As the sprocket spacing is the same for Shimano and SRAM 11 speed and practically the same for Campagnolo this cassette mounted to a wheel with a shimano freehub will work with a SRAM or Campagnolo 11 speed drivetrain.
The Miche cassette uses separate steel sprockets (except the last big sprocket which is heat treat alloy) and resin spacers. The lock ring is light weight aluminum alloy. The Miche cassette is available in ratios that are not available from Shimano. The sprockets in the light version are lighter. The big sprocket for the 30T version is aluminium.
