Whenever the drive-side crank arm is at the 12 o'clock position I am getting a clicking sound, and occasionally immediately thereafter in the 3 o'clock postion.
I just went out and got the Bicycling Magazing Maintence book, and it doesn't talk about this problem. This weekend I was planning on pulling out the assembly, cleaning it, looking for damage and re-lubing it.
Does anyone have an idea as to possible causes for the noise? When I am not actually riding, and putting pressure on the chain system, there is no noise at all. Even using a mechanic's stethoscope I cannot hear the noise.
Any help would be appricated.. Thanks!
