Ultegra Di2 R8050 Rear Derailleur - 11 Speed

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

• 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
