Split Belt Tensioning System provides constant tension and alignment to belt drives. This is a drop-in replacement for a worn or damaged tensioner.
It may be used to tension our belt drive when you have a split frame without a tension adjustment mechanism, such as horizontal dropouts or an eccentric bottom bracket. It also provides an extra layer of defense against belt slip ("skip" or "jump") on systems that run at low tension (Rohloff and many other internally geared hubs).
