    Excuse this maybe simple question but being a Campag user all my life, this ones stumping me!

    I bought a second hand bike to use for commuting, it has a Shimano 7 speed cassette. I stripped the
    whole bike down to clean and adjust everything but...have one bit over!

    I have a metal ring that obviously comes from the cassette as it has the cutouts for the freehub. I
    assembled all the rings and spacers back onto the freehub and later found the metal ring in the
    bottomm of my cleaning tray. It's metal, approx 1mm thick and 2mm wide at the most...it fits around
    the freehub. Question is where? Just before the lock ring, first on before the biggest ring??

    My fault I know, but can anyone supply the answer?

    Thanks in advance.

    It sounds like a shim to go on before the cassette, to push it out. Did the rear derailer require
    any adjustment after you put it all together?

    I can't tell because I fitted all new cables.

    It goes on before the 2nd smallest cog.

    Dear Mark,

    Wish I hadn't thrown out my box of old Shimano 7-speed stuff last week. Here's an exploded drawing
    from the old loosescrews catalogue that might help:

    They're still in business at www.loosescrews.com, but I saw no exploded drawings.

    Good luck,

    Between the highest and second-highest gear.

    Look at the cassette in profile and you'll see that the outside and second cog are obviously too
    close together without it.

    Look at the cassette in profile and you'll see that the outside and second cog or the second and
    third are obviously too close together without it.

    Under the last or smallest cog...

    Also possible that someone has fitted a Hyperglide-C cassette to a standard Hyperglide freehub and
    has used a spacer to prevent the lockring from bottoming out. If the bike has a 46T big ring but
    also has an 11T sprocket, that's probably it.

    Thanks for the replies guys.

    Strangely enough when looking at the profile the smallest gap was between the 2nd and 3rd cog in.
    Does it go there or between the 1st and second smallest??

    Good point.

    And that shim goes under the second cog in some brands of cassettes, under the last in others.

    Look at the cassette in profile. Shimano, SRAM and SunRace have various models. The spacer is a
    separate part because it levels the last surface where the rivets go through. That is cheaper than
    any other solution.

    Also, that shim comes in several thicknesses for different applications. I now that because they
    commonly fall out of the cassette boxes in shipping and you can't just grab any for a
    replacement. . .

    That's a freeWHEEL drawing, Carl. I'm afraid it's not going to help him much.

    Dear Chris,

    Sigh. Immediately after posting it, I smacked my head and said "D'oh!" and began hoping that no one
    would notice.

    Fat chance.

    Even worse, if you look closely, you can make out the lower part of the "FREEWHEEL" legend at the
    top of the picture.

    At least it had seven gears. I just got excited when I found my old catalogue.

    Why, I wonder, is it so hard to find exploded drawings of this kind of stuff on the internet?
    Wouldn't they save companies lots of time and trouble?

    Is it that companies can save even more time and trouble by not putting the diagrams up and blowing
    off potential customers who call for help?

    If so, why do the companies spend time and trouble putting up elaborate web sites that make it next
    to impossible to find anything useful?

    Hell, I look at the sites put up by dealers like Sheldon Brown, Andrew Muzi, John Dacey and others
    before I start looking at manufacturer web sites.

    When I replaced an ordinary household light switch last night, I wasn't surprised to find that I
    needed a test meter to find out which way was on. Despite all sorts of part numbers, patents, and
    other useless details, nothing on the switch indicated which position turned the lights on and
    should be up. Its lettering and legends were evenly divided in both directions.
