Abstract: Composite chains and associated methods are disclosed. A chain in accordance with one embodiment of the invention includes an arrangement of outer plates, and inner plates joined by connecting pins. Spacers can also be provided between the inner plates as separate components or as part of the connecting pins. The chain can be used for bicycles and/or other machinery. At least one of the components of the chain (e.g., the outside plates, the inside plates, the spacers, and/or the connecting pins) can include a composite material (e.g., a carbon fiber composite material).
