  1. The blurb for Cannondale's new frame says they have carbon
    fiber dropouts on the forks. I had not heard of this
    before... (I suspect these might be Time forks since that is
    what the Caad7 had.) Can people in the know comment on this?

    I am ok with Carbon forks, steerer, frame, stems, and
    handlebars, but dropouts seem to get a little scary. I would
    guess the normal mode is one of compression due to the QR
    skewers, but my Al ones have indentations worked in them
    from my zealous tightening. Won't this just crunch and crack
    CF dropouts in short order--perhaps removing surface chunks
    with each application?

    Cheers, Shawn

  2. I have a carbon fork with the carbon going all the way to
    the dropout. I've never seen another fork like that - every
    other CF fork I've seen uses aluminium dropouts. I make a
    point of not using extreme quick release pressure and the
    dropout has shown no more then slight cosmetic damage.

    sounds scary. Trying to balance enough pressure so that your
    wheel doesn't pop out with too much pressure that might
    damage the dropout. How much weight can these drop outs
    save? I can't see the weight savings making up for the risk.

    The carbon-legged fork on my Giant TCR2 seems to have carbon
    dropouts. tinyurl.comjweb

    I also have no more than slight cosmetic damage, and I also
    make a point of not using excessive force.

  5. Perhaps they are just as strong or stronger. And perhaps
    weight is not an issue, but durability. When you use
    continous fibers then you don't have to worry about the
    junction and the glue.

    I'm not scared, I just don't use excessive force. I use
    similar force that I usually use for front wheel skewers.
