    This is probably what you're looking for: http://www.chainreactioncycles.com/M...?ModelID=30631
    Sounds like you had an X4 model, so you'll want to stick with SRAM's X-series to match the cable pull of your current rear shifter. Just figure out from your old one whether you need the "long cage" or "medium cage" version.

    There may also be damage to your frame, particularly the derailleur hanger (where the rear mech (derailleur) bolts on). A mechanic at your local bike shop should be able to easily determine whether the hanger is bent and replace it or repair it.

    You don't, as they only come in the Long cage version, from your orginal post, you are saying you need an SX4, not an X4, there are a lot of different parts which SRAM produce, so would look at replacing like with like.

    When you say it snapped from the frame, did your frame have a replaceable hanger, as this may need replacing as well.

    Sorry to have misread the model number (thanks, jim!). According to my Google search, the SX4 seems to come in both medium and long cage versions, although the long cage version is more prevalent. A bike mechanic should be able to easily figure out which length you need by looking at your old one, or looking up the bike's original specs. If I had to guess, I'd go long cage as jim suggested.
