    What cog will give 45mm chainline?

    The crank I'm using provides a 45mm chainline. What cog or hub/cog combined will give me a 45mm chainline?

    What is the chainline for your hub? It might be easiest to get a shorter BB spindle than stuff around with finding a different hub.

    Look to Sheldon

    To determine chainline, you add the chainline figures from the hub and sprocket sections.

    Sheldon's chart does not include Paul's Track hub, which is spec'd to yield a 44mm chainline. Not quite 45, but pretty close.

    A cog with 3 mm of spacers between the cog and hub.

    Are you using a Sugino RD? Not to get off topic, bit I think it's really cool that Sugino decided to to offer that crankset in bunch of different anodized colors and didn't even try to fix the chainline issue. Smooth move.

    A few mm difference in chainline isn't that much of an issue, especially if you're running a mix match drivetrain.
