- Will not fiterror · Rear RotorRear rotor: a 6-bolt rotor does not mount on a Center Lock hub as it is - the two use different rotor interfaces. The part that bridges them is a Center Lock adapter, and the ones makers publish fit one-piece rotors only. A shim or adapter may make other sizes or standards work, but that is a modification, not a fit. On 19 of the 30 verified rotors in this catalog.
