However, the squeak tells me you've failed to properly lube the jockey wheel bearings.
What should I use to lube the bearings, grease?
Is there any way to reduce the noise that the chain makes when it makes contact with the jockey wheels? I know it's not really a technical problem but I feel that a noisy drivetrain hinders my performance on the bike.
