Thanks for the info. The noise is definitely when using the extreme gears and the chain is not straight. I have noticed that if i use a soft touch on the front shifter a second time (must be trim??) that the chain is in a better position and quieter.

Am in the process of looking for a new mechanic. Now I will be better able to discuss the problem and hopefully have it resolved.

Thanks. I enjoy all the great threads in this group.
