A hub shell (42) of a hub assembly (12) is rotatable about a fixed hub shaft (40). A power transmitting member (52) is disposed within the hub shell (42). A pawl supporting member (54) has at least one pawl member (78) movable between an active position where the pawl member (78) allows transmission of rotary power from the hub shell (42) to the power transmitting member (52) and an inactive position decoupling the pawl (78) from one of the power transmitting member (52) and the hub shell (42). A one way roller clutch assembly (56) is coupled between the power transmitting member (52) and the hub shell (42) and is movable between an active position where the roller clutch assembly (56) couples the power transmitting member (52) to the hub shell (42) to transmit rotary power from the power transmitting member (52) to the hub shell (42) and an inactive position decoupling the power transmitting member (52) from the hub shell (42).
