• If your BB30 is doing that, then there is nothing to diagnose as such: it needs to be stripped down, cleaned and reassembled.

    If it's four years old and you're taking it apart anyway, you might as well sling some new bearings in.

  • Sorry for the confusion, the bike and bb are only 6 months old and it's only really been ridden consistently since september so not very old. I was saying that I've had various bikes with bb30 over the past 4 years and have gotten away with no clicks or creaks, which is fairly lucky I think.

    Probably worth greasing pedal threads again before I go to town on it. Also going to invest in a bigger range torque wrench, the 42nm figure seems to be pretty crucial according to some.

  • If it's still under warranty, I would let the shop/dealer sort it out.

    If the shell is off (which it may be, bearing in mind how new it is) then there's little that can be done to fix it.

    You won't get a new frame if you've pulled it apart.
