A disc brake rotor comprises a hub engagement member, an outer member, and a coupling arm. The hub engagement member is configured to engage with a hub assembly. The outer member is provided radially outwardly of the hub engagement member with respect to a rotational axis of the disc brake rotor. The coupling arm extends radially outwardly from the hub engagement member to the outer member. The coupling arm includes a first axial surface provided on a first axial side in an axial direction with respect to the rotational axis and a second axial surface provided on a second axial side reverse to the first axial side in the axial direction. At least one of the first axial surface and the second axial surface is non-parallel to a reference plane perpendicular to the rotational axis as viewed in a radial direction with respect to the rotational axis.
