Hi, I have a new road bike with Ultegra front rings, Tiagra 9 spd cassette, and HG53 chain. The front derailleur is not touching the chain, but there is an audible noise when in the largest sprocket and the next to largest. Looking down onto the front inner chainring, it does appear that the chain is being bent significantly and this is making the noise.
Will this noise go away? I am using Pedros Dry lubricant and everything is quite clean. The bike only has 40 miles on it.
I am pretty sure it's not the rear derailleur B adjustment, as rotating the rear body in a vertical plane (simulating B adj) doesn't reduce the noise.
I searched for other similar posts and found one person that had similar issues, but am curious about some compatibility issues.
Is Tiagra cassette ok with the Ultegra front rings (probably)? Is the HG53 chain ok with the Ultegra front rings? The Shimano tech document CS_6500_SI.pdf (9-Speed Cassette Sprockets - CS-6500) says
"
Do not use the CS-6500 in any combination other than with the
CN-HG92, CN-7700. Other chains cannot be used as the sizes do
not match.
"
Any thoughts? The rear wheel is an ALX-300, but I have also put a 9speed Mavic Cosmo in the back and heard the same thing.
Does the Ultegra HG92/HG93 chain bend better than the Tiagra HG53? Would another lubricant be better (I read somewhere else they were saying stay really wet for this)? And should I break in this chain (if that's the solution) by trying to stay out of these gear combinations?
