Abstract
Chain hanger devices are described for attachment to a bicycle frame for supporting and retaining the drive chain vertically and laterally when the rear wheel and drive sprocket are removed from the frame. The hanger devices engage the chain without requiring manual manipulation of the chain. The rear wheel can be inserted into the frame again without physically handling the chain.
