drivetrain noise
(OP)
I am posting this on behalf of someone at bicycling.com. I suggested that he is setting up a resonant vibration mode and to check compatibility of his chain with the cranks and also to see if the rear derailleur pulleys were tight and lubed./Bearach
"What's the deal with drivetrain noise?
Currently, I am riding a Campy Veloce equipped bike. It has about 1500km on it at the moment. When I ride in the 39 ring, there is no noise. When I ride in the 53 ring, there a consistent buzz in most gears. It has always done this, though it is not as pronounced now that the drivetrain is somewhat worn-in.
Why is it silent in one ring, but not in the other? The chain isn't skipping, I've made sure of that. The chain is adequately lubricated as well, so I know I don't have any awful metal-on-metal problems"

RE: drivetrain noise
The chain tension will change, also the reletive frequencies of the gear teeth engaging the chain will be different. This could cause the chain to vibrate. Try a different lubricant. That may dampen things a little.

I have forwarded your answer to the bicycling.com forum
RE: drivetrain noise
I would suggest it is a simple matter of chain alignment... one cog to the next relevant to the rear cluster.
