    I have been told that these ball bearing pulleys are ment to be great. Has anyone ever used them? Also the bottom pulley on the shimano stuff is what they call a floating pulley. Do the ball bearing pulleys cater for this? Shimano say that having the bottom pulley floating and the top one fixed gives better performace?

    stick with the shimano pulley, they are quiet, aftermarket aluminum ones are very loud and offer no advantage

    I agree with tjstoner, the shimano stuff works very well.

    I don't know about the lower end Shimano pulleys, but the lower pulleys on 8-speed DuraAce are with ball bearings, and both pulleys on 9-speed DuraAce are with ball bearings.

    I had bought some aftermarket aluminium pulleys. The quality of the sealed cartridge bearings in these pulleys may not be as good.

    I used to use the control tech and carmichael pullies, and before that, the bullseye models, with sealed bearings..

    Stick with the shimano or campy ones you have. The ceramic/plastic makes for less wear and noise than the aluminum, and the rollers in the shimano and campy pullies have less friction in the first place..
