The great thing about SRAM is that, with only a few exceptions, most of their groups all work exactly the same way. X.4 shifts almost exactly the same as X.0, what you really pay for is lighter weight materials that shed a few extra grams. That's why the X.4 9-speed rear derailleur is such a great deal. You still get 1:1 actuation and Direct Route cable routing technology for easier, cleaner shifting. It's easily one of the best values you'll find on a long-cage mountain bike rear derailleur anywhere.
