    Rollers gremlin

    This winter I had "incidents" while riding on the rollers:

    1- Two flats. The first one due to a cut in the valve caused by the valve hole edge, riding with low tire pressure (understandable). The second one, I can't explain.

    2- Last night, without obvious cause I heard a loud "pop", and immediately felt increased resistance. See the pictures below. It's a Mavic Open pro rim with about 12K-14K miles on it. WTF?

    It happens. Rollers didn't cause it, unless you've been using your brakes on them. Alot.

    More likely, though is a manufacturing defect, something I've come to expect from Mavic. The brake track looks good and not terribly worn through. How long have you had the wheel?

    Yup, not a problem with your rollers. Your rims have worn out. Simple as that. It's happened to me a couple times in the past few years. If you ride in the rain a lot, 14k miles is about all a Mavic open pro rim can withstand. Mavic designs optimizing for weight and strength, not durability and longevity. I've worn out two in the same manner over the last six years.

    Gremlins will loosen your seatpost binder bolt ever so slightly. Soon your knees will be up around your ears while you ride. Now, how did THAT happen?
