Chain-drive systems and methods of operation are described that allow chain travel along a non-linear path. In one example, the chain-drive system comprises a chain guide defining a channel having at least one non-linear region. A chain, sized to move within the channel, is driven by a drive sprocket. In one example, the non-linear region could redirect the chain 180 degrees and obviate the need for an idler sprocket. In another example, two channels are defined in the chain guide, including regions wherein the channels are parallel and regions where they have an angularly skewed relationship.
