    Avid Mech funny noise

    I'm getting a funny noise from the front set up only. It sounds like the inboard adjuster knob is hitting the spokes. (like if you spin the wheel and clink your finger nail against the spokes as it spins) But it is NOT hitting the spokes. I'm sure of that. Positive.

    Only a few miles on them: less than 100.

    My first diskos.

    Any guesses? Or is it break in noise?

    Thanks

    You got the "musical" model

    check spoke tension. I had some tunes on Mavic 223/Louise XC brakes and never really resolved it, but they always worked fine.

    Realign the caliper. It is probably the edge of the pad or H clip spring catching in the rotor slots.

    The trouble with common sense is it is no longer common

    I had a front wheel, my first with 110 spacing, where I did have some spoke contact with the inside knob, so I used spacers to solve the problem (it wasn't quite enough for the cps adjustment alone). It didn't ping in the stand, tho, just sometimes while riding....drove me nuts for a while.

    When you say reallign the caliper you mean loosen the mounting bolts so that it can move aroung on the spherical washers?

    The h spring is the little h shaped spring that pushes the pads away from each other correct?

    Thanks shiggy and others. I'll keep trying. Part of the problem is that I don't fully understand the system. It looks fairly simple, so I should get it soon.

    The slots on your rotor are probably catching on something. Mess with the allignment, you'll get it eventually. It's really not a big deal, eventually it'll wear down whatever it's rubbing/catching on.

    I understand

    Yeah I can see how allignment would cause noises if the pad and the rotor aren't close enough to the same plane.

    Yes and yes.

    Loosen the bolts just enough to allow the caliper to move. Then squeeze and hold the brake lever and tighten the bolts.

    I've had similar issues...

    I've been running avid mechs for years. Every once in a while, if I am not careful when re-installing the front wheel, one of the thin little h-clip tabs that hold the pads apart gets caught on the wrong side of the rotor. Take close look at the caliper and make sure both tabs are not on the same side.

    The more I think about it, though, my sound was more like a dragging than a spoke "ping".
    Anyway, careful inspection should reveal your issue because the Avids are beautifully simple system.
