An assembly for a drug delivery device is provided comprising a housing, and a lead screw having a longitudinal axis, a distal end and a proximal end, the lead screw being rotatably fixed during dose setting and dose delivery and axially movable in a distal direction relative to the housing, the lead screw further including a thread. The assembly further comprises a drive nut threadedly engaged with and screwable along the lead screw thread and a dial link connected with the drive nut and axially movable and rotatably fixed relative to the drive nut, where the dial link comprises a first portion of a feedback ratchet. The assembly is configured such that, during dose delivery, the assembly generates a feedback signal.
