    Cannondale Paint Crazing

    I'm assuming it's an efflorescence of the aluminum. Anyone else get alum corrosion under their paint. Is there any way to halt it?

    There is a possibility of getting corrosion under the paint. If there's trapped moisure during the painting process, this can eat away at the aluminum and cause corrosion. I wonder if this is a warranty item? You can usually strip away the paint, sand away the corrosion and repaint it with primer properly. That will usually get rid of the problem.

    I feel more like I do now than when I first got here.

    I seem to recall it was a suspension rather than an outright ban. I hope he returns, I quite miss the old grouch.

    Greg - talking to a metal fabricating colleague, your diagnosis sounds correct as is Chi's solution.
    Currently riding an MTB with a split personality - commuting, touring, riding for the sake of riding, on or off road :)

    I have had paint problems on 'dales over the years. They always seem to spread from places where another metal contacts the aluminum frame. When you have 2 metals in near contact and a little salt (sweat) what you have is a battery or instand corrosion.

    My experience does not sound quite like yours though.

    Also, hosing the bike down after rides with a water bottle seems to help ****** the process by washing off the salt.
