    Ogre Rohloff conversion. Chainline/crank compatibility.

    Hi, I intend to purchase a new Rohloff which I believe has a splined sprocket requiring a 57mm chainline. I wish to use my existing shimano FC-m622 crankset which has a chainline listed as 50mm. I cannot find the chainline measurement for the centre of the outer ring. Can anyone enlighten me?
    Will I be able to achieve the required 57mm chainline with this crankset and how can I achieve this?

    The 50mm chainline for the cranks is measured to the middle ring. They have 3 rings, so mount your chainring on the outer position and you'll get very close (if not exactly) to 57mm.
