This adapter allows conventional three-compartment MTB cranks with 104mm bolt circle diameter to mount a two-way system. With the widespread solution easy to assemble the large sheet on the middle position, there is a risk that the large sheet grinds on the chain stay and the shift quality on the basis of poor chain line decreases.
With this adapter, these problems can be effectively avoided. The adapter is simply screwed onto the position of the large sheet of the 3-crank and thus allows the assembly of the large sheet of the 2-fold solution to a meaningful center position.
