Description - Shifter Shimano ULTEGRA Di2 ST-R8070 11-speed

The Shimano Ultegra Di2 ST-R8070 dual control lever for rear 11-speed derailleur. Allows not only more intuitive shifting operations but also quick and precise shifting thanks to a clearer separation between shift buttons. A more defined click feeling and a wider reach adjustment range generate even more comfort. Group-specific each switch has the option for multi-shift ON or OFF. The STI's top button remote switch is programmable for third party cycle computers. Every function is compatible with E-Tube application or Shimano PC software. The Ultegra Di2 dual control levers in hydraulic disc version improve rider control in all conditions. The small bracket size feels great on the palms and improves the ergonomics. On top of that lightweight materials make the STI's race-ready.

Di2 - The advantages of Di2 (Digital Integrated Intelligence) are clear for everybody who has tested it: changing gears becomes easier, effortless and faster by simply touching the shift buttons. Control at the top of your fingers. Additional benefits include an automatic trimming front derailleur, unmatched precision plus super easy installation and adjustment. This allows automatic chain guide movement in response to the gear position of the rear derailleur. There is no more need for concentration on trimming when riding.

Important: All Shimano Di2 electronic components require the same firmware version. In order to diagnose, read or update firmware, an optional device is needed. Operating components with different firmware versions may cause malfunction or loss of function.
