Shimano Ultegra ST-R8150 Di2 Mechanical Levers Pair

Shimano Ultegra ST-R8150 Di2 Mechanical Levers Pair Perfect for upgrading a rim brake bike; Shimano’s Ultegra ST-R8150 Di2 Mechanical Levers Pair offers 12-speed electronic shifting and powerful braking. Near instantaneous; precise gear changes are actuated by just a light press of the appropriate lever; even when the drivetrain is under full load; and the E-Tube app adds shifting customisation options. The fully or semi synchronised modes automate certain elements of the shifting for a smoother ride and the lever functions can also be altered and personalised. Braking is always assured with the Servo Wave lever in connection with the Super SLR calipers; bringing improved power and modulation for the utmost confidence and control. Small and large hands can be comfortably accommodated by using the lever reach adjust and the hoods have also been improved ergonomically for greater comfort. These mechanical brake shifters need to be wired into the Di2 system.
