The Rohloff DH chain tensioner is specially designed for downhill use. In contrast to the standard 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.

Advice:
The Rohloff DH Shorty is your choice if you want to ride your single-speed-bicycle a bit rougher. 

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