If you're looking for the smoothest shifting available then look no further than Shimano's Dura-Ace 7900 series rear derailleur. The new model is even more precise than previous versions of the highly touted Dura-Ace line. Now using a carbon fiber pulley plate Shimano has shaved the weight of their pro level derailleur down to 116 grams. When matched with 7900's shifters it also has an enhanced pulling cable method with a wider adjustable range for shifting, and can accommodate a wide range of gearing, including triples. If you are after shifting excellence the Dura-Ace 7900 rear derailleur is the only choice.
