A protector device for the sprocket of a bicycle. A protector device has a curved arcuate configuration that underlies the profile plane of the sprocket when the device is installed on a bicycle. Two struts extend upwardly from the protective device at its leading and trailing ends. Clamps are carried on the upper ends of the struts for attaching the protective device to the bicycle frame. One of the clamps has a swivel connection to the associated strut, to enable the device to be operatively attached to a range of different bicycles.
