Abstract
A chainring protection system includes a chainring having a torque input section and a torque output section. The torque output section is radially outer relative to the torque input section and has a plurality of teeth. The chainring protection system also includes a cover connected to the chainring, such that the cover at least partially covers a circumferential portion of the torque output section. The circumferential portion of the torque output section includes less than all teeth of the plurality of teeth.
Claims17
A chainring protection system comprising:
- a chainring having a torque input section and a torque output section, the torque output section being radially outer relative to the torque input section and having a plurality of teeth;
- a backplate;
- and
- a cover having a connection to the chainring spaced a radial distance outward from the torque input section, such that the cover at least partially covers a circumferential portion of the torque output section of the chainring, the circumferential portion of the torque output section including less than all teeth of the plurality of teeth,
- wherein the cover is configured to interface with the backplate, such that the cover is connected to the chainring.
A cover for a chainring of a bicycle, the cover comprising:
- a body including a circumferential portion and at least one radial portion, the at least one radial portion extending radially inner relative to the circumferential portion;
- an opening extending at least partially through a radial portion of the at least one radial portion;
- a raised surface being positionable within a vacancy of the chainring,
- the raised surface completely surrounding the opening;
- and
- a threaded insert positioned within the opening.
A chainring protection system comprising:
- a chainring having a torque input section, a torque output section, and at least two openings through the chainring, the torque output section being radially outer relative to the torque input section and including a plurality of teeth;
- at least two backplates;
- at least two covers having a connection to the chainring spaced a radial distance outward from the torque input section, wherein a first cover of the at least two covers at least partially covers a first group of teeth of the plurality of teeth, and a second cover of the at least two covers at least partially covers a second group of teeth of the plurality of teeth, the second group of teeth being different than the first group of teeth;
- and
- at least two fasteners configured to connect the first cover and the second cover to the chainring via a first opening of the at least two openings and a second opening of the at least two openings, respectively,
- wherein the at least two covers are configured to interface with the at least two backplates, such that the at least two covers are connected to the chainring.
