It doesn't matter how your derailleur does what it does, as long as it keeps doing it when the trail conditions get nasty. For 2011, Shimano has designed a rear derailleur to do exactly that -- no sick days, weather delays, "wardrobe malfunctions" or hiccups -- it does what it does, period. The reengineered architecture on this Shimano rear derailleur gives you a smooth, linear feel at the shifter, and remains stable in the midst of suspension movement, trail chatter or the ever-present dirt factor. If you need a rear derailleur that doesn't make excuses, you need the new XTR.
