    What do all the different lengths mean, short, medium, long? Also new x9s seem to be pretty cheap on ebay. Any reason why? Also Does the year really matter?

    The cage length effects the tooth capacity of your drivetrain, long cage having the largest capacity, basically dictating which gear ratios you can select. Short cage deraillers are a little lighter (barely), and I should think are marginally less likely to strike rocks etc, but I've always used long cage so I don't know which is actually better. As for whether this years sram stuff is better than last years, I have no idea, haven't used it, sorry.

    Get shortest possible jockey arm that will work with your gear ratios. It will lead to crisper shifting and les to get into your spkes. I run a road derailleur on my DH bike for those two reasons.

    I picked up an x-9 medium cage der. Supposed crisper shifts, less chain slap, and some other stuff. Had it for about 4 months (?), but not that much riding (winter). Maybe 15-20 rides or so.

    From what I can tell it seems shifts nicely compared to my old x-7 that I bent the crap out of, at least from what I remember. The shorter cage is also nice b/c not as close to the ground.....very slight diff, but who knows how that extra bit might help out.

    Big/small gear is a no-no as the der will fold back in on itself, but that much chain cross isn't good anyway. However, i've gotten away with 'almost' the big small combo (by accident of course).

    Hope that helps
