This adapter allows conventional 3-compartment MTB cranks with 104 mm bolt pattern to fit a 2-fold system. With the widespread solution easy to assemble the large leaf on the center position, there is a risk that the large sheet grinds on the chain stay and the shift quality decreases on the basis of poor chain line.
With this adapter, these problems can be effectively avoided. The adapter is simply screwed onto the position of the large leaf of 3-crank, allowing the installation of the large leaf of the 2-fold solution to a sensible, middle position.
