The ST-R8060 Brake and Shift levers take inspiration from the lighter Dura-Ace shifters, with an aero-focused design and single-button shifters. With the evolution of Syncro Shift, the Di2 system optimizes front and rear gear combination when you shift the rear derailleur, which reduces both time spent shifting and dramatic cadence changes between gears. This single button design is easy to use, and since it's programmable you can decide your shifter functions based on personal preference completely. It pairs with Shimano's E-Tube wires that install right into the lever, and are compatible with nearly any aero bar capable of internal routing to keep things clean and rattle-free.
