with ceramic bearings - look lush but really? Are they worth the cash? How much difference to weight/overall perfromance can ceramic bearings in jockey wheels make?

    Doubt they make any difference at all, but they did spin noticeably smoother than the campag ones they replaced.

    Depends on how much effort you're prepared to keep them clean, the maintenance on the rest of your drivetrain and the quality of ceramic bearings - dirty ceramic bearings run just as rough as everything else. There are plenty of ceramic bearings that still use chrome-steel housings, means that if they get wet, they corrode and can still seize solid!

    a bit lighter...run really well & look P1mp !

    i only do bottom one in shimano DA r/d as top one i like to have a bit of float

    i have tuned rd with KCNC jockey / Ti bolts for cable & adjuster
    SRP alloy hanger bolt ( also acts as a 'breakaway' in event of crash )
    also Fibre lyte carbon cage plate & Ti Cage bolts....

    cheap tuning & good results !

    Weight wise they'ra approximately 0.5g per jockey wheel than Dura Ace IIRC.
    Rule 64:

    Cornering confidence generally increases with time and experience. This pattern continues until it falls sharply and suddenly.

    They sound cool. Obviously they're better than the Shimano ones as I guess are the campy ones but are the KCNC ones better than the campy?

    Is it worth buying a full tuning kit with all the bolts and stuff for a record group?

    no do not buy the full kit the chainring bolts strech and become loose and the rear mech main bolt being ally seizes up badly, :?
