Updating their ever popular Ultegra Di2 line of electronic shifting, the Ultegra ST-8050 Di2 Shift/Brake Levers offer an updated and improved design, providing a Di2 shifter that offers more intuitive shifting and braking.

The shift buttons themselves have received an updated, featuring a clearer separation between buttons with a more defined response on activation making it easy to locate and operate, even with heavy winter gloves. Further, each shift button can be programmed for multi-shifting via Shimano's e-Tube project.
