Abstract
A bicycle chain ring having a plurality of teeth extending radially about an axis of the chain ring, the plurality of teeth including a first group of teeth and a second group of teeth. The first group of teeth has a first width at a tooth base that is sized to be received within a chain cavity defined between parallel links of a bicycle chain. The second group of teeth has a second width at the tooth base, the second width being different from the first width. Further, the first group of teeth have a tooth tip that is substantially centered on a plane defined between an inner surface and an outer surface of the chain ring and the second group of teeth is at least partially offset from the plane.
Claims10
A bicycle chain ring, comprising:
- a plurality of teeth extending radially about an axis of the chain ring, the plurality of teeth comprising:
- a first group of teeth having a first width that is at least 96% the width of an outer link gap of a bicycle chain;
- a second group of teeth that are at least partially offset from a central plane to a first side and have a second width;
- and
- a third group of teeth that are at least partially offset from a central plane to a second side opposite the first side;
- wherein, the first group of teeth have a base that is sized to be centered on a central plane defined through a center portion of the chainring;
- wherein the chain ring has a repeating series of teeth comprising:
- a first tooth from the first group of teeth;
- a second tooth from the second group of teeth;
- a third tooth from the first group of teeth;
- a fourth tooth from the second group of teeth;
- a fifth tooth from the third group of teeth;
- and
- a sixth tooth from the second group of teeth;
- wherein the repeating series repeats at least two times consecutively around the chain ring.
A bicycle chain ring, comprising:
- a plurality of teeth extending radially about an axis of the chain ring, the plurality of teeth including a first group of teeth and a second group of teeth and a third group of teeth;
- wherein the first group of teeth has a first width at a tooth base that is sized to be received within a chain cavity defined between parallel outer links of a bicycle chain, the first width being at least 96% a chain cavity width defined between the parallel outer links;
- wherein the second group of teeth are at least partially offset from a central plane to a first side and have a second width at the tooth base, the second width being different from the first width;
- wherein the third group of teeth that are at least partially offset from the central plane to a second side opposite the first side;
- wherein the chain ring has a repeating series of teeth comprising:
- a first tooth from the first group of teeth;
- a second tooth from the second group of teeth;
- a third tooth from the first group of teeth;
- a fourth tooth from the second group of teeth;
- a fifth tooth from the third group of teeth;
- and
- a sixth tooth from the second group of teeth;
- wherein the repeating series repeats at least two times consecutively around the chain ring.
A bicycle chain ring, consisting of:

- and
- a third group of teeth that are at least partially offset from a central plane to a second side opposite the first side;
- wherein the chain ring has a repeating series of teeth comprising the following consecutive order of teeth:
- a first tooth from the first group of teeth;
- a second tooth from the second group of teeth;
- a third tooth from the first group of teeth;
- a fourth tooth from the second group of teeth;
- a fifth tooth from the third group of teeth;
- and
- a sixth tooth from the second group of teeth.
