1. A chain guide assembly comprising:
a backplate, the backplate configured to be coupled with a frame of a vehicle and oriented with respect to a sprocket, the backplate comprising:
an elongated opening therein; and
a chain guide, the chain guide comprising:
a guide configured to orient a chain with respect to said sprocket; and
a retaining assembly configured to removably and adjustably frictionally couple said guide at a given location along the elongated opening in said backplate, such that when said guide is rotated axially about said retaining assembly, said guide is retained at said given location, wherein the retaining assembly comprises:
a fastener configured to retain said guide and pass partially through said elongated opening in said backplate such that said guide is on a first side of said backplate;
a nut located on a second side of said backplate opposite of said guide, said nut configured to retain said fastener with said backplate, wherein said backplate further comprises:
an indexing track about a portion of said elongated opening; and
a frictional spacer retained by said fastener between said guide and said backplate, said frictional spacer comprising:
an indexing feature configured to maintain an orientation between said frictional spacer and said backplate; and
a protrusion configured to provide a frictional connection with at least a portion of said indexing track of said backplate, said frictional connection configured to maintain said guide at said given location when said fastener is loosed such that said guide can be rotated axially about said fastener, wherein said frictional spacer is a portion of said guide.
