Description

  • Digital Integrated Intelligence or Di2: with programmed automatic motion at the touch of a switch the Dura-Ace Di2 rear derailleur is quick, smooth and effortless, making for unmatched drivetrain efficiency
  • 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
  • Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift
  • Synchronized Shift designed, developed to choose the next biggest or lowest gear ratio irrespective of whether a gear change needs to be made by the front or rear derailleur
  • The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching
  • Low profile Shadow derailleur design
  • Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts
  • 11-34T wide gear ratio capacity will cater for compact setups as well as the traditional road double
  • Full carbon fibre inner and outer pulley plates enhance rigidity and reduce weight
  • Titanium B axle bolt for further weight savings
  • 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
  • Pulleys are made of tough DuPont Zytel for longer life and less chain noise
  • 12-speed E-tube Di2 compatible
