I have a very annoying creak which is getting worse, and seems to be coming from my headset whenever on rough or rocky ground. So far, I have:
removed and refitted handle bars/handlebar clamp
removed and refitted stem from steerer
removed forks, greased the steerer, all the bits of the headset and the headset spacers (inc the plastic washer).
The headset is a CK and the fork steerer is slightly scored. It is this which could be responsible? Worth getting a new style top cap for the headet, or just replaced with an FSA/something with tapered wedge fitting? The bearings are still nice and smooth, and the cups are not moving within the frame.
Tempted to buy this if it will fix it!
Cheers!
