    Fractured rear derailler Shimano RSX

    I need to find and order a new rear derailler for my old Trek 1200 Road bike. It has (had) a Shimano RSX. There are 8 sprockets on the back wheel. I called Bike Nashbar just now and they said that they don't sell any rear deraillers for an 8 sprocket wheel.

    Any suggestions?

    Thanks

    The person at Nashbar is just wrong. Any rear derailer will work. The shifter controls how much cable pull or release to index the shifting, and the limit screws control how far the derailer moves. Best bet is to get a 5600 105 derailer. The derailer doesn't care. I'm using one with a 7-speed RSX shifter with no problems.
    Bikes use brakes to stop.

    If your bike has breaks, don't ride it.

    They lied.

    Any 8-9-10 modern Shimano indexed speed rear derailleur will work.
    For example, Tiagra:

    There are some derailleur that won't work but any Shimano 9-speed derailleur will work, and a 10-speed Shimano derailleur will probably work.

    Why a RD 5600 105 derailer?

    Okay. That makes sense that the derailer doesn't care. Why did you recommend the 5600 105 derailer? It looks to be about $75 to $90. Obviously I'm a newbie, but just want to make sure I am selecting the correct part. Could I spend less, or is this the "minimum" quality level?
    Thx

    Even Shimano Sora for $20 will work. And it even says 8-speed.

    Here it says

    Shimano RD-3300 Sora Rear Derailleur 8 Speed SS Silver

    but you can see RSX in the picture:

    Almost, not quite. You need a Shimano RD, 8, 9, and 10-speed Shimano derailleurs all have the same throw ratio except for pre 9-speed Dura-Ace.

    I was basing the recommendation on performance value. For dirt cheap replacement, there is Shimano 2200. No name, just the product number.

    If it's a triple, go with the $20 Deore derailleur on Nashbar. No need to put a 105 on there, IMHO.
