SHIMANO ST-R8050 Di2 brake/shift lever for mechanical rim brake (left or right)

The Shimano Ultegra ST-R8050 STI brake/shift lever combination for mechanical rim brakes has everything you need to set your bike up perfectly in the race against time. It is not only the slimmer styled handle horns that lead to improved ergonomics and thus to better intuitive control.

Electronic shifting via the Dual Control (STI) levers gives the ultimate feeling of individual precision. Even with thick gloves, the clear separation between the shift buttons is noticeable thanks to better click feedback. With Synchro-Shift, the rear derailleur and front derailleur can be operated with one shift knob for optimal positioning of the gears.

Under the top cover of the brake lever combination, there are also programmable buttons for controlling gear changes, third-party devices or compatible additional components such as bike computers. Multi-Shift can be switched on or off individually. All Di2 settings, from shifting speed to Synchro-Shift and Multi-Shift options, can be easily be adjusted via the SHIMANO E-tube app.
