Shimano Dura Ace Di2 2X11SPD STI Shifter / Brake Lever ST-9070
  • Di2 Only
  • Includes left and right lever set

State of the art electronic Di2 technology provides direct, fast and precise shifting at the touch of a button - and always at a consistent, unique high level. This technology is now 11-speed compatible and characterized by an improved feedback and optimized ergonomics, which for example makes the buttons from the top even more accessible. The E-tube technology with four-wire cables make it possible to install them visually elegant. So this also allows the use of numerous auxiliary switchs on time trial arms or in the top link position.

Note: In order to ensure proper functioning of the electronic Di2 drive system, all components require the same firmware version. The optional diagnostic device allows for reading out or updating the firmware version. An operation of components with different firmware versions may cause a malfunction or loss of function.
