I bought a cheap one last night on the way home from work from halfords (yeah i know) and it doesn't fit over the locknuts/axle gubbins so I want to make sure that doesn't happen again!
Everything I see says cassette, but no mention of centerlock compatibility.
Any decent cassette lockring tool, or external (old hollowtech/gxp) BB if it's one of the ones for through axles.
