I posted a while back on a strange clicking which I thought was coming from the bottom bracket. I took it to one LBS and they could not get the clicking to occur.
Plus they told me the only noise they could here was coming from the headset and that the bearings were shot. They said they would have to replace those before doing anything. The bearings have been on order for a week now.
If I turn the handlebars sharply with the tire off the ground I could hear a clicking but it was a different click coming from the steering then the one I was hearing.
The other thing that is disturbing is that they told me my chain was stretched and needed to be replaced. I measured it myself with my handy dandy chain checker and it did not looked stretched to me.
So I went out for an evening ride tonight and the clicking persisted. I was fairly certain that it was not in in the headset.
So I decided to stop in to a local REI. First he checked the chain and I was right, it was not stretched. Turns out the clicking (at least the one I can hear) coming from the steering was the cable barrel adjuster slapping the steering tube.
REI wants to replace the bottom bracket based on my assumption that the real clicking is coming from the bottom bracket.
I need to pack the bike up for tour next Friday so I can't mess around any longer. How many miles should I get out of a bottom bracket? I have about 12K. I would think I should get more miles than that. But if it is about due anyway, it would not hurt to have it replaced, if it is really the source of the sound or not.
