  • Q&A
  • 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.
  • 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.
  • Wireless data network system unit is integrated into the derailleur.
  • The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminants, corrosion and stretching.
  • Low profile Shadow derailleur design.
  • Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts.
  • 11-30T 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.
  • 11-speed E-tube Di2 compatible.
  • Max front difference: 16T.
  • Total capacity - 35T.
  • Weight - 204g.
