    SRAM bottom bracket: Warranty?

    This is my first rodeo with SRAM. It's on a new bike that's rockin' an Eagle XO drivetrain. The bike started creaking about 250 miles, and now it's got 450 miles on her.

    Last night I pulled off the BB to give it an exam. I was shocked to see the plastic bushing on the drive side worn through in two spots. They're 180 degrees apart, and you can see the area in the pictures.

    What's up with this? I've run thousands of miles on XT's, XTR's, and King's, and never had the plastic wear out. It's always the bearings that start to go. If I had thousands of miles on this BB, then I wouldn't be irked. But this only has a few hundred miles on it!

    If there are any SRAM reps following this forum, PM me with a phone number where I can send you the mailing address where you can send a replacement. Or just tell me that this is to be expected, and I'll let it go.

    Are you referring to the two 'half moon' cutouts in the inside diameter?

    Those seals come with those cutouts. I noticed them on a new SRAM BB that I installed on my wife's bike. I think they are supposed to be used to remove the dust seals with a screwdriver or other device. Seems unusual that they are 'half moon' shaped though. There should be no relative movement there to wear. That remains snug and rotates with the crank/spindle.

    Although not very clear, these images show that 'half moon' cutout in a new, uninstalled BB for my wife's bike.

    Epic fail!

    Maybe you can send SRAM an apology letter.

    It's just an over-reaction to an honest mistake.

    Thanks for the pics, Cleared.
    I decided to slap in a competitor's BB, and the GXP is now a spare in my parts drawer.

    Don't think so, he rips SRAM and demands them to fix it, when it was his fault all along. How about owning up?

    People always assume the worse in companies or people, he could make it right by editing the original post or a mea culpa. I bet if he ripped on your reputation, you would still feel the same?
