On frames where the Rohloff Speedhub hubs cannot be moved horizontally, a chain tensioner is required to ensure the chain is properly tensioned. The DH chain tensioner, with its short tensioning arm, keeps the chain particularly taut. And the chain guide ensures that the chain does not fly off the sprocket, even during the most violent impacts. Compatible only with 15–17-tooth sprockets.
