The Shimano SM-RT30 lockring is the Center-Lock lockring that secures the brake disc to the hub. It is made from steel and designed for hubs with 15 mm and 20 mm thru-axles, so the first thing to check is your wheel's axle diameter.
To choose the right replacement, compare the SM-RT30 model with the lockring you are replacing and check that your hub is compatible with the two diameters listed. A steel lockring is a component to check along with the disc, as it holds the disc in position on the hub.
