Creak coming from somewhere

[fossyant]

If you've an alloy steerer, you need to check that where the headset compression split ring washer is, that neither surface is 'blackened'. I used to get this on my 'work' bike every so often. Bit of sandpaper on the steerer and the compression washer, clean up, grease, re-assemble.
