Abstract: A chain damper for use with a bicycle may include a base having an attachment region that is configured to be attached to a bicycle and a chain receiving portion extending from the base in a first direction. The chain receiving portion can include a chain damping surface that includes a resiliently deformable damping material and at least partially bounds a chain receiving aperture. The chain receiving aperture may extend in an axial direction and may be configured so that when the chain damper is attached to the bicycle the axial direction is substantially aligned with the primary chain direction and the chain damping surface is spaced apart from the chain travel path.

Abstract: An adjustable locking mechanism may include a base member having an anchor portion and a first bearing surface. A flexible, rope like retaining member may have a body portion that is resiliently compressible and defines a retaining member width and that may be substantially inextensible along its length and the body portion. At least first and second securing recesses may be formed in the base member and can include a receiving portion configured to accommodate the body portion of the retaining member, a throat portion extending to the receiving portion and having a throat width that is less than a receiving portion width and the retaining member width, and a shelf surface formed at the intersection of the receiving portion and the throat portion and facing the receiving portion.
