Shimano's Ultegra Rear Derailleur benefits from trickle-down technology from Shimano's top-line Dura-Ace model, which means you get awesome shifting at a more affordable price point. This choice derailleur boasts a light and tough cold-forged-aluminum body with a wide pivot design that boosts rigidity to speed and smooth shifts. Plus, the fluorine-coated pivots minimize friction for nearly effortless shifting and the oversize pulleys keep the chain running more smoothly, too. The pulleys also last longer than smaller ones and are sealed to keep out water and dirt.
