    I need a tutorial...

    on derailleur pulleys. It's about time for new pulleys for my Dura Ace 10 sp. Is there much difference between pulleys whether materials, bearings or whatever?

    Folks in the Mechanics section would probably have:

    A.) the best, or
    B.) a wide ranging and contradictory set of

    answers to this question. I myself have no clue, and am merely bumping this thread with a "get thee to the bicycle mechanics section, where all thy pulley ponderings will be prolifically and profoundly pontificated upon."

    What makes you think you need new pulleys? I ask because I haven't had a Shimano derailleur pulley ever look worn out, or had the bearings go bad.

    Can you really trust anyone under 50? Or at least not in the 50 and over group.

    I have only ever bought a spare set of jockey wheels for any of my bikes. Don't know why I bought them but stripped the derailleur-an XT by the way- and cleaned everything up and looked at the new wheels. The old wheels cleaned up had no wear on them and the bearing surface- once greased- turned better than the new ones. Still have those new ones in the shed somewhere.

    The replacement jockey wheels were not Shimano by the way but were not cheap either.

    Which speaks to one of my questions: Are the $129 replacements better in some way than the $15 ones?

    If you have already bought the expensive replacements, then yes they are definitely better.

    I have bought one set of replacement jockey wheels in the entire time I was riding. last year I won a Shimano 105 RD that flatly stated it needed jockey wheels but I got it for a song and it was in excellent shape. I went back to eBay and got a stock set for $10.00 as well as some spares I put in my box for another $10.00. I looked at the ceramic bearing wheels but they were way overpriced at $60.00+ and some at $150.00 for a few. I could not justify the expense when the new stock that perform well were within my budget. But then I operate on a really low budget all the time, save a good N+1 and PIE!
