Brand new 11-speed Di2 rear derailleur from Shimano. This Dura-Ace shifter is the state-of-the-art rear derailleur from Shimano. It offers the best shifting, while also being low-weight. It comes in a sleek, shadow design, which limited to the best groupsets of Shimano. This is the SS version, which implies that it has a short-cage. Consequently, it can accommodate cassettes with up to 30 teeth. Furthermore, it can be set up with Shimano Syncro Shift such that it communicates with the front derailleur and always keeps the chain in the optimal angle.
With Di2 technology, shifting is made easy and accurate. A light touch, as soft as a click of a mouse, is enough for the rear derailleur to instantaneously select the correct gear. Furthermore, the removal of mechanical cables in favour of electrical wires not only eliminates poor shifting as a result of contaminants, corrosion, and stretching, but also provides smooth and effortless shifting.
