  • Patent number: 11820457
    Abstract: A suspension assembly for a cycle includes a link and an indicator having a central opening. The indicator includes a first retention feature. A pivot assembly is disposed in the link. The pivot assembly includes a second retention feature. The first retention feature and the second retention feature cooperate to axially retain the indicator on the pivot assembly while allowing rotational movement between the indicator and the pivot assembly when a force threshold is exceeded.

  • Publication number: 20220363335
    Abstract: A pivot assembly for a cycle linkage suspension is provided that includes first and second members and a pivot. The first and second members include lateral openings extending therethrough and the pivot includes a rod portion that is configured to be disposed within the lateral openings to pivotably couple the first and second members together. The rod portion further includes an opening that extends through an intermediate portion thereof. The pivot assembly can further include a pin configured to be removably inserted at least partially into the opening in the rod portion to thereby restrict lateral movement of the rod portion within the first and second members.
