Shimano Ultegra Di2 6870 11Speed Rear Gear
Precise, lightning-fast shifts across an 11-speed cassette, whatever the conditions, with just a button click. 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.
