I have a bit of a Frankenstein Shimano 105 R7000 11s mechanical set-up on my gravel bike. I have 105 shifters and derailleurs with with an 11-40 cassette and a 30-46 Shimano GRX crankset. The maximum for the 105 rear mech is supposed to be 34 teeth, I think, but it all seems to work without any adapters.
This is because there are a lot of not particularly long, but steep climbs where I live on the North Downs and I sometimes travel loaded with panniers, etc.. It's absolutely not because I'm old and not very fit.
I keep my drivetrain pretty clean and well maintained, but lately I've noticed it's a bit noisy. The chain isn't worn, comfortably below 0.5% according to my chain checker. The chain doesn't seem to be rubbing on the front derailleur cage. Also, it's not that I'm severely cross-chaining, this is while I'm cruising along using the front outer ring and the outer half of the rear cassette.
I've previously had 7, 8 and 9 speeds, and they generally stayed pretty quiet, if well adjusted and maintained. Maybe I've been spoiled by the dead silence of the Gates belt drive and hub gears on my other bike.
Is it typical for an 11s drive train to get a bit noisy once they have a few thousand kilometres on them, or is something off? Would new jockey wheels help? Any suggestions appreciated.
