    By using a SS freewheel on my multi-speed hub, what can I do to adjust the chainline? Are there any
    spacers that I can thread on to the hub before threading on the SS freewheel? ...so that I can
    insert the freewheel at which ever position that will give me the optimal chainline? Thanks.

    Ring on the inside of the crank-redish the wheel after moving spacers right side to left
    side-raising the tension of the left spokes(a good thing)

    Wouldn't do this if using a freewheel type hub, need the threads to hold the SS freewheel.

    Freewheel spacers or cassette spacers put under the freewheel will move it outward but you don't
    want to do that.

    You need to get the bottom bracket that gives you the proper chainline.

    Generally, the threads on a freewheel hub are not long enough to give you sufficient
    adjustment for this.

    The correct way is to move axle spacers from the right side to the left side until the hub has moved
    far enough to the right to get the chainline correct. (You may have to replace one thick spacer with
    a bunch of thinner ones to make this redistribution possible.)

    Then you need to tighten the spokes on the left side of the wheel to bring the rim back to the
    middle of the frame.

    Would using long crank bolts with "home depot spacers" a good idea if the BB axle is too long and
    you don't feel like replacing the BB?

    When we speak of crank bolts, we're generally speaking of the bolts, one per side that hold the
    crank to the bottom bracket axle. If that's what you're asking, the answer is, no, it won't work.

    What does work is using spacers between the arms of the crank spider and the chainring, on the
    chainring bolts (usually 5, sometimes 4 or 3.)

    If you remove one chainring from a typical crankset, you can add a 3 mm spacer in its place, using
    the same bolts. These spacers need to be 10 mm inside diameter. It happens that such spacers are
    commonly sold for use on rear hub axles.

    We sell sets of them for the purpose of adjusting chainline on our Website.

    There's a photo showing how this works at

    Thanks. I will head on over and grab a set. I was there yesterday and today getting some Mafac brake
    parts as well as other parts... Would using 2 spacers per bolt a problem? Seems to me that the screw
    should be long enough (without affecting structural integrity?)...

    If you space behind the freewheel, ensure that you have full thread engagement between the freewheel
    and the hub's aluminum threads. Change the axle spacing if you need to correct the chainline. Center
    the rim over the locknuts after changing axle spacing.

    It would have no effect on the spindle-crank position to move the bolt heads out farther . The bolt
    heads would hit your ankles if you stick 'em out a long way!
