  • Ultegra Shadow design with Di2 technology, shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear
  • The rear derailleur is now the brains of the system with wireless connectivity to the shifters. It acts as the point the system is charged, provides ANT+ connection to 3rd party devises and replaces the handlebar junction
  • Button on the derailleur for Di2 operations, and LED light denotes synchronized shift mode, setting mode and charge requirements
  • Sleek appearance with Low profile Shadow design construction reduces risk of damage in a crash
  • Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift
  • The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts
  • Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts
  • High tolerance cold forged aluminium link plates and body construction is extremely light and durable
  • Four self-lubricating micro-machined fluorine-coated link pivot bushings provide low-friction shifting
  • 12-speed E-tube Di2 compatible
  • Wide gear ratio compatible up to 11-34T
