Cross Country Chain Tensioner

The Rohloff Chain Tensioner is a spring loaded device that maintains chain tension in a single driveline application. It should be used with the Speedhub when horizontal adjustment of the hub is unattainable or in rear suspension applications where the distance between the bottom bracket and rear axle change throughout the range of travel. The Rohloff Chain Tensioner is an excellent choice for any conversion to a single driveline system (i.e. Speedhub or singlespeed).

The Rohloff Chain Tensioner

The Chain Tensioner is easy to install, it simply mounts to the existing derailleur hanger on the frame. Spacers are used for lateral adjustability.

For the quick wheel removal the Rohloff chain tensioner swings back when pulling the wheel out of the dropouts. The Rohloff chain tensioner has a tensioning capacity of 10 chain links which is sufficiant even for long travel rear suspensions.

Down Hill Chain Tensioner

The Rohloff DH chain tensioner is specially designed for downhill use. In contrast to the regular Rohloff chain tensioner, it has a shorter swing arm that is restricted from moving. This feature ensures that the upper jockey wheel runs very close to the sprocket. This forced guide guarantees a positive run of the chain onto the sprocket even under extreme riding conditions. To remove the wheel, the chain tensioner mounting bolt must be loosened.
The Rohloff DH chain tensioner has a tension capacity of 10 chain links. It is mounted to the gear hanger of the frame. The adjustment to the correct chain line can be achieved by shims.

On dropouts thinner than 7mm, the use of the 13 tooth sprocket (chainline 58mm) will require the use of the longer mounting bolt. This is available separately.
