    Rear Derailleur compatability question

    When I started riding last summer I picked up Schwinn Circuit 24 speed. Eventually I will pick up a better bike, but this frame is good enough for now and I really can't justify the expense of a new bike at the moment. I know that can't make a silk purse out of a sows ear, but there are some improvements that I'd like to make. Primarily, the rear derailleur is a Shimano RD2200 and has been getting a little sloppy. I keep it adjusted and it shifts decently but I would like to pick up a different derailleur and swap it out with something a little better.

    I have a triple in the front so I know that I need a long cage.
    I also know that the width of chains for 9 and 10 sprocket cassettes are narrower than what I have with the 8 sprocket that is currently on my bike but I don't know if that will present any problems.

    Any recommendations or suggestions?
    Old enough to know better and old enough to forget that I do.

    I would ride what what you have until it breaks if it was my bike. On the other hand you have money burning a hole in your pocket replace it with a long cage 105 or Ultegra. Roger

    I know a "9-speed" Ultegra rear derailleur works fine with a 7/8-speed chain as I had that combination on one bike for quite a while so a 9-speed 105 should work as well. I don't know if the 10-speed road derailleurs will work or if the cage and pulleys are narrower enough to give problems.

    One option is a MTB rear derailleur as these are all 9-speed, almost all long cage, and a Deore LX or XT are good components at reasonable cost.

    If you'd like a Shimano Ultegra, but $80 - $100 is too steep:

    No joke - these are brand new and shift flawlessly. I bought 3. So far.
    How do you keep an idiot in suspense?

    How about a Nashbar-brand rear derailleur? $37 or something. I have no experience with it, personally, but it looks like a bargain, at that price.

    Anyone tried one?

    The rear der. won't make that much difference. If the cables are in good shape you would have better luck changing out the shifters.

    A lot of shifting problems get blamed on the derailleurs when the problem is more often the shifters or the cables and cable housings. I think derailleurs are usually the most dependable and longest lasting part of the drivetrain.
