The Shimano Rd-R8150 Ultegra Di2 12-Speed Rear Derailleur E-Tube Rear Mech features Ultegra Shadow design with Di2 technology, providing easy and precise shifting with a light touch. The rear derailleur acts as the brains of the system with wireless connectivity to the shifters, and it's also the point where the system is charged. It provides ANT+ connection to third-party devices and replaces the handlebar junction. The derailleur has a button for Di2 operations and an LED light that denotes synchronized shift mode, setting mode, and charge requirements. The Low-profile Shadow design construction reduces the risk of damage in a crash. The derailleur offers programmed automatic motion at the touch of a switch, making shifting quick, smooth, and effortless. The removal of traditional mechanical cables in favor of electrical wires eliminates poor shifting caused by contaminants, corrosion, and stretching, and provides effortless gear shifts. The derailleur contains a saver, or fuse.
