The electronic Shimano Dura Ace Di2 SW-R9160 bar-end shifter is especially designed for time trial and triathlon bars. The remote shifter features an incredibly low-profile design with a redesigned switch optimized for hand positioning on the extensions. So it is easy to push the thumb switch when gripping the top of the TT extension what makes a direct, fast and precise shifting possible. The one-button operation minimizes movement and maximizes the aerodynamic efficiency.

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.
