• So I have a noise that appears when on rougher surfaces and at higher speeds. It sounds like something is knocking as it’s a clunky sound, the frame is carbon fibre.
    I’m thinking either the B.B. or the headset?
    Any other suggestions or ways to further investigate this?

  • Have you just had the frame?
    I’ve read that sometimes lose pieces of the moulding process are left inside tubes. A way of finding out is by grabbing the frame and shaking it.
    It did happen in steel frames when some brazing pieces ended up lose inside and you can hear them.
