I've started turning my own wrenches on this old fixed gear and after overhauling the rear hub this weekend I noticed the chainline is far from optimal.

Sheldon Brown talks about adjusting the chainline with axle spacers but I don't fully understand what he means.

I am running a Suzue track hub (high flanges) with a Mavic rim that has virtually no dish. I tried moving the entire axle farther to the left but that did little to give me the line I wanted.

Any advice?

Thanks in advance,
