Shimano Ultegra Di2 Rear Derailleur

Shimano's electric-shifting Ultegra Di2 Rear Derailleur is driven by battery power and its servo motor, so shifts are fast, precise and perfect every time. It's made of light, tough cold-forged aluminum and has the chain-wrap capacity for standard and compact cranksets. Since there aren't any cables or housing to stretch or fail, maintenance is reduced dramatically and durability is increased. This high-tech derailleur is even designed to move inward under impact to reduce the potential for damage in a crash.
