Chain rattling on lower Jockey wheel on bigger cogs.
Hi all
I am putting my rebuilt powder coated bike back together (upgraded to 10 speed) and am running into an issue with the rear derailleur. It shifts nicely and I got it tuned but I can't get it to stop rattling on the rear jockey wheel on the big ring and to top 3-4 cogs. I know big big is cross chaining and I expect problems there but I should be able to use the second and third largest cogs. My other bike with a near identical setup only a 6700 RD is fine on all cogs though rubs the FD when cross chaining. I don't think the hanger is bent is is steel, part of the frame, and very thick and looks fine. I am wondering if getting a different pulley/jockey wheel (6700) would help. What do you think?
