Employing the latest technologies from elite Dura Ace R9100 road components and through its proven System Engineering approach, Shimano’s Ultegra R8000 series delivers refined rider ergonomics, increased shifting performance and confident control in all riding conditions. Riders who choose the Di2 shifting components (R8050) have further the possibility to turn on or off the multi-shift function as well as to customize every key's setting individually.
The Shimano Ultegra Di2 ST-R8050 dual control levers allow 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 to E-Tube application or Shimano PC software.
