    CAAD10 Bottom Bracket Click

    I have a CAAD10 that I bought a couple months back that recently has developed a loud click (or creaking) sound that occurs only after about 5 minutes on the drive side when the crank arm reaches the 5 o'clock position. It is only under moderate to hard efforts.

    It happens seated and standing
    It happens whether Im wearing my riding shoes or tennis shoes
    If I have it on the trainer I can pedal it with my hand and reproduce the sound

    The sound is like (I say like because this is not the case) the crank arm hitting the frame, it is quite loud. I don't notice any resistance change in pedaling near that spot.

    It is quite annoying...any ideas what I should check?

    There are lots of threads discussing BB30 (and I'm assuming that's what you have) noise and solutions. Suggest you do a search.
    There's sometimes a buggy.
    How many drivers does a buggy have?

    One.

    So let's just say I'm drivin' this buggy...
    and if you fix your attitude you can ride along with me.

    BB30 + specific loctite # = problem solved (do a quick search and you should find the magical loctite that the BB30 actually requires to prevent the infamous clicking.)

    This sounds basic I know, but, do you have a bike computer and a cadence sensor fitted on your crank? Check whether the sensor magnet or the reader on the downtube have moved as they be too close and hitting on rotation - perhaps the sound is coming from the opposite crank arm with the magnets hitting at 11 o'clock rather than from the other crank at 5 o'clock.

    (Don't ask me how I know this can sound like a bottom bracket click…

    either the bearing have gone bad or you need to install the bearings using the proper Loctite product.

    I also had the similar issue of the crank arm hitting the FD.
