Shimano RD-6870 Ultegra Di2 11-Speed Rear Derailleur E-Tube, SS Cage

Brand:Shimano

Code:RD6870SS

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.

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
  • 11-28T wide gear ratio capacity will cater for compact setups as well as the traditional road double
  • 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
  • 11-speed E-tube Di2 compatible
