It's hard to overcome the giddy feeling of tweaking your ride with Shimano's new Dura-Ace Di2 drivetrain but for those of us who ride TT or triathlon there was always a problem. There's no doubt about it that we don't like to open the tuned aerodynamic position for braking or gear shifting on the outside handlebar and fortunately Shimano Dura-Ace Di2 ST-R9160 TT 11-speed brake/shift levers eliminate this problem. together, allowing you to stay in position with the gear shifters neatly secured to the ends of the TT's handlebars. These shifters are configured to shift gears in sync and are fully programmable with multi-gear capability allowing you to select the ideal forward ratios for moving off from a standstill.

The ST-R9160's brake and gear levers are somewhat inspired by its predecessor , ST-9071, but are lighter, more compact and convenient. Besides The gear shift levers have been changed from the two-button style of yesteryear to a single-button style. Thanks to the development of Syncro Shift, the brain of the Di2 system determines the optimal combination of forward and reverse gears every time when you change gear using the rear derailleur which significantly reduces the amount of time which you need to spend interacting with the switch as a whole so you can stay in the most aerodynamic position stay steady and focus on the road ahead of you. This one button design is quite easy to use in real world conditions , and , since it is programmable you can completely select the switch functions based on personal preference. It is combined with Shimano E-Tube cables, which mount directly into the lever and is compatible with almost any aerodynamic handlebar having an internal gasket to keep it clean and rattle-free.
