Shimano Ultegra Di2 11-speed Rear Derailleur E-tube RD6870

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.

Key Features:

• 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 gives effortless gear shifts
• Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts
• 11-32T or 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 give low-friction shifting
• 11-speed E-tube Di2 compatible
