Rim brake ready, the Shimano Ultegra R8050 Di2 11 Speed Levers combine with your road bike's E-Tube electronic drivetrain for fast and effortless gear changes and reliable stopping power. You can also customise the control button's functions. A clearer separation between the shift buttons on the Shimano Ultegra Di2 shifters ensures precise shifting, even when wearing thicker gloves. Each switch can be used for multi-shift ON or OFF and top hood buttons can be programmed to control third-party devices. All functions can be customised through the Shimano E-Tube app or PC software.
