I'm looking to replace the pulleys on my RD-5700GS with something that doesn't require quite so much maintenance to keep them from squeaking. For reference, this is for my randonneuring bike. I started a 1200k last weekend with freshly cleaned and oiled pulleys. By the end of the ride they were squeaking so bad the other riders were asking what was wrong with my bike. Are the 7900 pulleys the right choice for that?
