A wonderful creation of Yess Products, a spring loaded tensioner that has the effectiveness of a derailleur, but stays neatly tucked underneath the chainstay. It mounts to the skewer and the derailleur mount, and uses a spring-loaded arm to keep tension constant. Adjustable to push up or down, as well as side to side to accommodate different chainlines.
It now comes standard with the F/S kit, which adds a second pulley on the tensioner for even better results.
The axle mount(meant for a skewer or small bolt) can be modified/drilled to accommodate a larger axle if necessary. Of course, that's something you would have to do on your own...
