Rohloff DH Chain Tensioner 8245

The Rohloff DH chain tensioner is 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 has to be loosened.

The Rohloff DH chain tensioner has a tension capacity of 10 chain links. It is mounted to the derailleur 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 with Speedhub 500/14 (chainline 58mm) will require the use of the longer mounting bolt. This is available separately.
