A disc brake rotor adapter is configured to detect a rotational state of a bicycle wheel. The disc brake rotor includes an adapter and a magnetism generation device. The disc brake rotor adapter is configured to attach a disc brake rotor main body to a hub of a bicycle. The adapter includes an adapter main body, a magnetism generation portion and an attaching portion. The adapter main body includes an inner portion and an outer portion. The inner portion includes a second spline configured to be engaged with a first spline provided on the hub. The disc brake rotor main body is coupled to the outer portion. The attaching portion attaches the magnetism generation portion to the adapter main body in a manner irrelevant to a fixing function of a fixing member. The fixing member is configured to fix the adapter to the hub.
