  1. I know this has probably been rehashed a few times, but - I have an 8 speed Sachs freewheel on a 130
    spaced Zipp 3spoke that I would like to use on my TT bike. I can't get the shifting to work across
    the range. I am using DA bar ends with a DA 7700 RD. It works fine with an 8 or 9 Shimano cassette.
    The freewheel I have has the "brown" spacers. Can one get one of these freewheels to work well with
    the Shimano set up? Are there some special spacers?

    Separate but similar question - will a Campy 9 wheel work with a Shimano shifting system as I have
    noted above?

    Spacing is different for a 8s or 9s casette so unless the 8s is somehow spaced to 9s, cannot work.
    The Sachs FW is spaced like a shimano 8s casette(brown spacers) and will not shift well with DA 9s
    shifters of any kind.

    Friction mode of the shifters.

    Ah, but you're forgetting the alternate cable routing option at the rear derailer.

    See: http://sheldonbrown.com/dura-ace.html#alternate

    You wouldn't want to go back and forth frequently, 'cause you can only do that a couple of times
    before the cable gets all frayed and needs to be replaced.

    D-A 8 and Other Shimano 9-speed pull the same amount of cable per click

    I thought they were going to skip over 10 and go right to 11...

    Well, it's one louder, isn't it? It's not ten. You see, most blokes, you know, will be playing at
    ten. You're on ten here, all the way up, all the way up, all the way up, you're on ten on your
    guitar. Where can you go from there? Where?

  6. I've actually tried many combinations of shifting stuff. Shimano 9speed STI will work with 7, 8, or
    9 Shimano spacing. As Sheldon says, you change the cable anchor point to the other side of the RD
    (for 7, 8). The problem with what I am using seems to be in the FW spacing. I can get it to shift
    across either the lower 5-6 cogs or the upper 5-6 cogs, but not all the way across. I thought maybe
    there was some fix out there that was known. Mike "Sheldon Brown" <[email protected]> wrote
