Every time I turn the crank, when the right arm hits about 1 o'clock, it makes an audible clicking sound. It doesn't do it when I'm just holding the bike and turning the crank, only when I'm actually riding. I took it to the LBS and they "went through the BB" whatever that means. It went away for about a week then came back. I don't want to take it back there because they usually have about a four-day turnaround and I don't want to be bikeless that long again.
Any ideas? I've got an 05 Giant TCR C3 with a Truvativ Rolleur crank and no idea what kind of BB.
