Title says it all- Noticed it Sunday at the start of the ride, but too late to sort out. Moving the bars and there is a definite click on the headset- Just stripped it out and it is sealed bearings so took them out and moved them looking for the click to show a broken cage or ball out of place- Nothing. Put it back together and moved the bars and the click is still there. Took it apart one bit at a time- First off came the cables from the bars and found it- The rear deraiiler outer cable is a bit too tight on the bend and it has a click on the metal braiding. Thats a bummer as I do not want to disturb the rear derailler on any setting yet to see how cable stretch affects it. Just have to put up with the noise for a few weeks.
Incidentally- Nice to have room in the New shed to work round the bike- Couldn't do that in the Garage, although now the bikes are out of the Garage- I probably could now
