Best-Selling Rohloff Chain Tensioner – 10 for XXL Hubs

For fatbikes and singlespeed: the Chain Tensioner-10 by Rohloff

In addition to the Rohloff standard chain tensioner for Speedhub 54 mm chainline, there is also the chain tensioner-10. This is required for the Rohloff Speedhub 148 mm Boost hub and the XXL hubs with 190 and 197 mm.
The chain tensioner-10 is also suitable for use with other hub gears and/or for use on singlespeed bikes. Depending on the derailleur hanger thickness (max. 8 mm) and axial offset (aV), a chainline of 42-50 mm (aV=0) and 50-58 mm (aV=7.5) can be achieved.
The Rohloff chain tensioner-10 has a tensioning capacity of 10 links and a chain line that is offset 10 mm inwards. It is screwed into the derailleur hanger of the frame with a fastening bolt. The lateral position is adjusted via spacers.

Note:

If the dropout thickness is less than 7 mm and the screw sprocket with 13 teeth is used, as well as all plug-in sprockets (chainline 57 mm), a longer fastening bolt is necessary (included). You can find chainline specifications at Rohloff.
