Abstract
A tension device for tensioning a chain of a bicycle includes a coupler for securing to the bicycle. A bracket is rotatably secured to the coupler and has a pair of lugs. A shaft is engaged between the lugs for rotatably supporting a sprocket which may engage with the chain so as to tension the chain. The sprocket and the bracket are rotatable relative to the coupler for suitably supporting the chain in place. The distance between the sprocket and the bracket is smaller than the width of the chain so as to prevent the chain from disengaging from the sprocket.
