The Dura-Ace Front Derailleur is Shimano's top-of-the-line front changer. The body is made of cold-forged aluminum for lightness with top-notch strength, and the pivots are extra wide for amazing shifting. The lightweight, replaceable aluminum cage is nickel plated for durability. Plus, the 7900 is designed to eliminate the need to trim the derailleur to prevent chain rubbing.
SRAM's X7 2x10 Front Derailleur is stiff, light and strong. It provides crisp, precise action for fast, smooth, and reliable shifting season in and season out.
