    Hi!

    I ask this question for someone on a German BBS, who has a 2001 10 speed Daytona with 12-25
    cassette. When the chain is on the 4 smallest cogs, he hears (rattling?) sounds. According to him th
    esystem is properly adjusted.

    sounds like it might be the chain rubbing against the large chain ring. such a problem can be fixed
    by increasing the space between the chain rings or by adjusting the chain line. if the flange on the
    left side of the small chain ring is thicker than that on the right side, flip it so that the
    thicker side is next to the large ring so as to increase the space between the rings. also
    installation of spacers between the chain rings will have the save effect (a bike shop can help you
    get the spacers). the chain line can be adjusted by installing a spacer in the bottom bracket to
    move the chainrings to the right (check w/a shop).

    If problem only happens when applying lots of torque, refitting the cassette with grease on the hub
    splines can prevent certain stange noises.

    Definitely don't do this. The ramps and pins on the chainring are *not* double-sided. Has s/he
    adjusted the der per the instructions,
    i.e., shift the der to the sixth cog and align (sorry, I had to ask)? I did notice that my
    drive-train required frequent lube (course, I use fairly thin lube) to keep it quiet and that
    the Campy drive train just seems to be noisier than the Shimano 8 I had been running. Perhaps a
    heavier lube? Also, I have noted that my Daytona 2001 cassette seems to be noisier than my 2002
    Centaur (psychological?).

    What chain is s/he using?

  6. << sounds like it might be the chain rubbing against the large chain ring. such a problem can be

    I agree that may be his noise but I disagree that it something that needs to be 'fixed'..Just
    shifting to the large ring and up a couple of cogs will make the noise go away and he will be in the
    same ratio.

    Adding spacers or futzing with the chainline only creates more problems, like poor fder actiopn or
    loosening rings BB cups.
