Shimano RD pulley, bushings vs. sealed bearing. Are different models interchangeable?
I have a 105 5700 RD on my bike. I notice that there is a bit of noise from the RD pulleys, kind of a muffled clacking. It's worse on the 50t front chainring. Everything is aligned, nothing is bent. The RD shifts crisply without any problems. I know the the 105 5700 uses bushings, not sealed bearings. My wife's Ultegra 6600 is much quieter, and I believe that it uses sealed bearings.
Can I replace the bushings on my 105 5700 with Ultegra 6700 (or 6600) or DA 7900 sealed bearing pulleys?
I'd just replace the RD, but mine is black, and the others are silver.
