Abstract: Tuned mass dampers are disclosed, and that are configured to cancel vibrations of a component of a bicycle at a natural frequency of the component in response to operation of a disc brake assembly of the bicycle. For instance, the component may comprise one or more frame members (e.g., the entire bicycle frame) of the bicycle and the damper may be engaged therewith and configured for cancellation/dampening of vibrations at the natural frequency of the bicycle frame as measured at the frame member to which the damper is attached. Accordingly, when a driving force is imparted to the frame member by operation of a disc brake assembly at a frequency at or near the natural frequency of the bicycle frame, the damper may counteract such vibration.
