Ever since I installed a 7900 compact crankset and chain there is a lot of noise when using the large chainring. I have had this setup on two different bikes with both a 7900 and 7800 chain and both are noisy. Lubing the chain helps but it doesn't last very long. From what I read this is a common issue with 7900 and it may get quieter as it wears in. I believe the large chainring has something to do with it. I am wondering if a different chain might help. I have a KMC X10 chain on another bike and it seems like a nice chain and has a quick link instead of the stupid Shimano installation pin.
