The Rohloff chain tensioner is a spring loaded device that maintains chain tension in a single driveline application. It should be used with the Rohloff SPEEDHUB 500/14 when horizontal adjustment of the hub is unattainable or in rear suspension applications where the distance between the bottom bracket and the rear axle change throughout the range of travel. The Rohloff chain tensioner is an excellent choice for any conversion to a single driveline system.
The Rohloff chain tensioner is easy to install, it simply mounts to the existing derailleur hanger of 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
